User Innovativeness and Fintech Adoption in Indonesia

: The integration of the ﬁnancial industry and ﬁnancial technology (Fintech) plays a pivotal role in increasing ﬁnancial services reach and inclusion for the large unbanked population in Indonesia. Fintech adoption optimization expands the ﬁnancial access to formal ﬁnancial institutions, especially to vulnerable groups such as the unbanked population who predominantly reside in rural areas far from formal ﬁnancial institutions. Fintech is viewed as a game changer to bring ﬁnance to the unreached communities via information technology and digital ﬁnancial landscape. In this causal research, data collection was done via online questionnaires to 485 Fintech users between December 2020 and April 2021. Data analysis and path modelling was performed using smartPLS 3.0 software. Result shows user innovativeness as a signiﬁcant predictor, directly and indirectly affecting the adoption of Fintech in Indonesia, while user attitude found the most important factor towards Fintech adoption. Financial literacy is the least important variable to predict Fintech adoption, contrary to popular belief. This indicates that Fintech usage requires less ﬁnancial literacy and is potential to reach unbanked population and those with low ﬁnancial literacy. To make Fintech more inclusive, the government needs to accelerate improving Information and Communications Technology (ICT) infrastructure such as widening mobile broadband penetration and soft infrastructure by encouraging Fintech startup, allowing regulatory sandbox for startups, and driving ﬁnancial institutions to innovate through Fintech to bring ﬁnancial services to unbanked population.


Introduction
Innovation, technology, and advancements in information and communication technologies have affected every facet of human life as it brings incremental changes to the economy. These advancements have brought about disruptive changes in the financial sector. The development of financial technology (Fintech) is an innovation that helps people do financial transactions with ease and speed. Fintech portrays wider user-reach offering financial services and its quickly gaining user bases across the globe. In adopting Fintech, customers are more influenced by the perception of benefit compared to the risk associated with Fintech adoption [1,2]. Indonesia, as a developing country, not only has limited funds to enhance its financial accessibility and infrastructure, the country also has high percentage of unbanked population. Fintech could serve as a game changer in bringing financial products to the currently unreached and unbanked population in Indonesia. Referring to World Bank Global Findex 2017, the unbankable population in Indonesia reaches 95 million population, behind Pakistan (100 million), India (190 million), and China (225 million) [3]. Fintech adoption can benefit the unbankable population, sector has entered its third phase, reinforced by the presence of new start-ups that can interlink between financial products and technology to directly provide the needs of financial services for individuals and companies.
Nowadays, the existence of Fintech is more advanced than a decade ago. Fintech service is not only applied to the financial and banking industry, but also has expanded to various other sectors such as telecommunications, airlines, and wholesales [17]. The development of Fintech is driven by various advantages over conventional financial services, such as real-time process with 24 h and seven days service with a low cost, which has an excellent benefit for people, especially the rural society who lives far from the bank ecosystem [18]. The convenience of Fintech and its economic benefit encourage people to adopt and use it in daily life despite their concern to security risk that embed in the technology [19]. Government intervention accelerate the penetration of Fintech service such as e-payment [20].
Fintech service is still not adopting equally in many countries as describe by Ernst & Young Report [21] that 87 out of 100 consumers in China and India have adopted Fintech, compared to 35 and 34 in France and Japan, respectively. The study from Ryu [22] explains that the barrier factors of Fintech adoption include financial risk, legal uncertainty, security and privacy, and the inadequate operational systems of Fintech companies. By embracing innovation, people may alleviate the risk that appear from adopting new technology [23]. Furthermore, low levels of financial literacy are also challenging to public awareness in Fintech adoption [24,25]. The initiation to investigate the impact of technology adoption was conducted by Davis [26] by proposing TAM to test users' internal beliefs toward the acceptance of information technology. The TAM model aims to identify the modifications that must be implemented to the new technology accepted for users and be adopted in a final stage. Several recent works have integrated TAM and technology adoption in varying sectors; i.e., TAM to measure adoption in insurance customers' intentions [27], mobile banking [28], and credit card [24].
Hu et al. [29] extended the TAM model by adding new variables such as user innovation and government support as Fintech adoption determinants in China. The structural equation modeling (SEM) analysis revealed a significant correlation between brand image, government support and user innovation to Fintech adoption. In contrast, perceived ease of use does not significantly impact Fintech usage in China.
The recent study by To and Trinh [25] investigates Fintech adoption in Vietnam by focusing on the influence of behavioral intention (perceived ease of use, perceived usefulness), trust, and perceived enjoyment of mobile-wallets services. The result implies that perceived ease of use, perceived usefulness, and enjoyment have positive and significant impacts on behavioral intention to use M-wallets, while there is no direct impact from trust to M-wallets usage in Vietnam.
Further, the institutional theory (IT) explains the process of organizational and reasons behavior, including the effect of organizational patterns in a broader scope. Currently, IT has shifted from a closed system to an open system, including embracing various aspects, such as technology [30]. For example, Teigland et al. [31] depict that institutional theory integrates the institutional-level changes that occur, as has been the case with the emergence of Fintech. A new study integrating institutional theory and Fintech adoption is conducted by Braido and Klein [32] in Brazil. Their study concludes that institutional theory supported the organizational changes related to the mobile payment system's regulatory, normative, and cultural aspects.

The Determinants of Fintech Adoption
This study aims to investigate the determinants of Fintech adoption in Indonesia. Several variables such as financial health (FH), brand image (BI), perceived ease to use (PEU), perceived usefulness (PU), attitude (AT), financial literacy (FL), user innovativeness (UI), and government support (GS) is applied as an independent variable, which predicted to influence Fintech adoption in Indonesia. Referring to Hu et al. [29], these determinant variables are adopted from TAM, the most widely used and good explanator for Fintech adoption. To extend the analysis, financial literacy, and financial health are added to predict Fintech adoption.

Financial Health (FH)
Joo [33] defines an individual's financial health as a comprehensive concept that cannot be identified by one measure since it integrates financial satisfaction, financial situation, attitudes, and behaviors. For this study's purposes, financial health is evaluated by looking at respondents' attitudes regarding financial allocation and management during the COVID-19 pandemic. Previous studies found that financial health has a positive relationship with Fintech adoption [25,34]. Based on previous research, the proposed hypothesis is: There is a positive relationship between financial health and Fintech adoption in Indonesia.

Brand Image (BI)
Brand image plays an essential role in creating trust for financial technology users. Moreover, transactions of Fintech services are carried out without involving direct contact among parties. Previous research on brand image and technology adoption was conducted by analyzing various aspects, for example, the brand image associated with quality [35]; brand image is integrated with a brand equity [36]. This study looks at a brand image with user preferences in choosing Fintech companies based on well-known brands, including company reputation. The empirical study of Hu et al. [29] and Caviggioli et al. [37] explains that brand image has a positive relationship with Fintech adoption. Therefore, the proposed hypothesis is: Hypothesis 2 (H2). There is a positive relationship between brand image and Fintech adoption in Indonesia.

Perceived Ease to Use (PEU)
Perceived ease of use (PEU) is associated with the level of individual effort to use new technology [26]. In this study, PEU was measured by the efficiency when using Fintech services, including assessing the Fintech service interface, and the ease of access to Fintech services from various electronic devices. Previous research that integrated PEU with technology adoption was conducted by Kanchanatanee et al. [38]; Wang et al. [39], and Hu et al. [29]. All the results of these studies explain that PEU has a significant relationship with technology adoption, except Kanchanatanee et al. [38] reveals that there is no correlation between perceived ease of use and technology adoption but found there is an indirect relationship between perceive to use and fintech adoption. The study also analyzes the relationship between PEU and Fintech adoption with the perceived usefulness as a mediated variable by considering that perceived usefulness is often plays a pivotal role in technological adoption. Based on the empirical study above, the following hypothesis is proposed: Hypothesis 3a (H3a). There is a positive relationship between perceived ease of use and Fintech adoption in Indonesia.

Hypothesis 3b (H3b).
There is a positive indirect relationship between perceived ease of use and Fintech adoption in Indonesia mediated by perceived usefulness.

Perceived Usefulness (PU)
Davis et al. [26] explained the perceived usefulness (PU) of the extent to which the technology can help improve performance. This variable plays a pivotal role in predicting technology adoption [40]. PU in this study is measured by evaluating to what extent Fintech adoption can fulfill the user needs, such as Fintech services can save time, and Fintech services provide benefits to users. Previous research has explained that PU positively correlates with technology adoption [41][42][43]. Based on previous research, the proposed hypothesis is:

Hypothesis 4 (H4).
There is a positive relationship between perceived usefulness and Fintech adoption in Indonesia.

Attitude (AT)
Ajzen [44] defines the attitude as a person's disposition to assess likes and dislikes towards an object, behavior, person, institution, or event. In this study, attitude is measured by investigating whether someone believes that using Fintech services is a good idea, their comfort level, and their interest in those services. Previous studies regarding attitudes and technology adoption explain a positive relationship between attitude and technology adoption [29,45,46]. Based on the previous literature, the hypothesis proposed is:

Hypothesis 5 (H5).
There is a positive relationship between attitude and Fintech adoption in Indonesia.

Financial Literacy (FL)
Financial literacy is the level of personal knowledge in understanding basic financial management information. Financial literacy in this study refers to the ability to understand compound interest, inflation, and risk diversification [47]. Previous studies by Junger and Mietzner [48] and Morgan and Thinh [25] explained that financial literacy positively correlates with Fintech adoption. Liu et al. [49] support the result by adding that financial literacy also aligned with the innovativeness. Based on the above literature, the following hypothesis is proposed for testing financial literacy on Fintech adoption: Hypothesis 6a (H6a). There is a positive relationship between financial literacy and Fintech adoption in Indonesia.

Hypothesis 6b (H6b).
There is a positive indirect relationship between financial literacy and Fintech adoption in Indonesia mediated by user innovativeness.

User Innovativeness (UI)
Lu et al. [50] described user innovativeness as the extent to which a person is willing to experiment with new technology. User open innovation can be accelerated by optimizing the use of external knowledge and information [7]. Meanwhile, Hu et al. [29] describe user innovation as the level of individual acceptance of new products, new technologies, or new services. The readiness to accept the presence of new technology is the main driving factor for technology adoption. The user innovativeness in this research is defined as an intention to try new technologies, to be a pioneer in using the latest technology, and a willingness to experiment with Fintech services. Previous research has explained that user innovativeness has a positive relationship with technology adoption [29,51,52]. Based on the previous literature, the hypothesis proposed is as follows:

Hypothesis 7 (H7).
There is a positive relationship between user innovativeness and Fintech adoption in Indonesia.

Government Support (GS)
Government support plays an essential role in the development of the Fintech industry. The government can be actively involved by making regulations that support the Fintech industry to continue to grow, both for Fintech companies, investors, and service users. The study conducted by Goo and Heo [53] explains that the government's active role has a positive impact on the development of Fintech by reducing uncertainty. Research by Marakarkandy et al. [54] explains that government support positively correlates with technology adoption. Government support in building hard infrastructure also needs to be supported by users' innovativeness by increasing knowledge about financial and technology literacy, including adopting Fintech products. In this study, government support is associated with the government's role in supporting the Fintech industry, such as laws and regulations that benefit the Fintech industry and infrastructure by expanding the internet network. Align with research framework on Figure 1, the proposed hypothesis is as follows: needs to be supported by users' innovativeness by increasing knowledge about financial and technology literacy, including adopting Fintech products. In this study, government support is associated with the government's role in supporting the Fintech industry, such as laws and regulations that benefit the Fintech industry and infrastructure by expanding the internet network. Align with research framework on Figure 1, the proposed hypothesis is as follows:

Hypothesis 8b (H8b). There is a positive indirect relationship between government support and Fintech adoption in Indonesia mediated by financial literacy.
Hypothesis 8c (H8c). There is a positive indirect relationship between government support and Fintech adoption in Indonesia mediated by user innovativeness.

Methodology
This study uses quantitative research with a Structural Equation Modeling (SEM) approach, using online questionnaire samples with purposive sampling and objects in the study using the criteria of Fintech users in Indonesia. Data were collected online by distributing questionnaires between December 2020 to April 2021, and a pilot survey was conducted first in November 2020 to confirm the validity and accuracy of the questionnaire. Feedbacks from respondents during the pilot survey helped enhance the final survey questionnaire, especially in replacing ambiguous words in the measurement state-

Hypothesis 8a (H8a).
There is a positive relationship between government support and Fintech adoption in Indonesia.

Hypothesis 8b (H8b).
There is a positive indirect relationship between government support and Fintech adoption in Indonesia mediated by financial literacy.

Hypothesis 8c (H8c).
There is a positive indirect relationship between government support and Fintech adoption in Indonesia mediated by user innovativeness.

Methodology
This study uses quantitative research with a Structural Equation Modeling (SEM) approach, using online questionnaire samples with purposive sampling and objects in the study using the criteria of Fintech users in Indonesia. Data were collected online by distributing questionnaires between December 2020 to April 2021, and a pilot survey was conducted first in November 2020 to confirm the validity and accuracy of the questionnaire. Feedbacks from respondents during the pilot survey helped enhance the final survey questionnaire, especially in replacing ambiguous words in the measurement statements with more straightforward, unambiguous, and specific words. After that, questionnaires were distributed to 508 respondents and upon data cleaning, 485 samples were finalized for data analysis.
The questionnaire used a Likert scale of 1 to 5 to measure all research items, from strongly disagree (1) to strongly agree (5). According to Loehlin and Beaujean [55], a good sample size should reflect its population and argued for a minimum sample size to reduce bias in SEM estimation. Hair et al. [56] explains if the population is unknown, the minimum sample number of indicators multiplied by 5; there were 34 indicators in this study, and thus the minimum sample required for this study is 170 respondents. The 485 respondents in this study exceeded the required minimum sample size.
The SEM with Partial Least Square (PLS)-based approach was applied in this research for testing the research hypotheses. SEM is a data analysis technique that can test a series of relatively complex relationships built simultaneously between the independent and the dependent variable, where each variable can be built from several indicators [56]. SEM aims to estimate the relationship between variables in a model, both between indicators and the relationship between latent variables. SEM is an approach that integrates two analyses, namely factor analysis and regression analysis. For two-stage SEM analysis with PLS, we first test the measurement model in the form of construct validity and reliability of each indicator; and second, test the structural model to determine whether there is influence between variables or correlation between constructs. The structure of the survey and the relevant studies are presented in Table 1. Government Support [53,54] The government support and improve the use of Fintech services GS1 The government has introduced favorable legislation and regulations for Fintech services GS2 The government is active in setting up all kinds of infrastructure such as telecom network which has a positive role in promoting Fintech services GS3

Characteristics of The Respondents
Most respondents in the study were female (62.1%). This is following the characteristics of Fintech users in Indonesia, who are less than 35 years old (72.2%), with the highest education levels being bachelor's degree (42.9%) and high school (36.7%). The majority of respondents (36.6%) in this study (see Table 2) had an income of fewer than 3 million rupiahs per month, and 24.9% have an income of more than 10 million. The majority of respondents in this study (84.3% with 33.6% experiencing once a month, 22.3% two-three times a month, and 28.5% more than four times a month) have used Fintech and 15.7% have never used Fintech; this corresponds to the age characteristics of predominantly young people who better understand and quickly adapt to technology.

Results of the SEM Analysis
Loadings, reliability, convergent validity, and discriminant validity were all considered when evaluating the measurement model. The first step in the evaluation was to look at the loadings of the indicators. Loadings are more significant than 0.7 use for acceptable item reliability. Table 3 shows, all factor loadings have exceeded 0.7. The second step was to determine the reliability of internal consistency [58]. Table 3 shows a composite reliability metric with a threshold value basis of 0.7. The composite reliability values of all constructs were more significant than 0.7, indicating excellent internal consistency. The third step involved determining convergent validity [58]. The extracted average variance (AVE) was used, with a value for each construct that should be greater than 0.5. that the AVE values shown in Table 3 explain for all constructs have exceeded 0.5. The fourth step was to determine the discriminant validity. To ensure that each construct is distinct from the others, we use different metrics. Henseler et al. [59] proposed using the heterotrait-monotrait ratio (HTMT) to test the discriminant validity of constructs. When HTMT values are high, problems arise; for similar constructs, the threshold value is (0.9). Whereas for distinct constructs, it is (0.85). All HTMT value in Table 4 shows a value lower than the threshold.  When the measurement model assessment is satisfactory, Estimate the structural model by examining its explanatory power and the statistical significance of the path coefficient. Before evaluating the structural model, the multicollinearity of constructs will review. Collinearity issues arise when the variance inflation factor (VIF) exceeds 5 [58]. Table 5 shows that the VIF values for all construct items were less than 5. the model's explanatory power assesses use coefficient of determination (R2). The coefficient of determination calculates for all endogenous constructs. The R2 value for the usage intention construct, as shown in Table 6, indicates that the model has moderate explanatory power.  The R 2 in Table 7 shows the ability of the research model to explain the contribution of the determinants to explain changes that occur in Fintech adoption, and R 2 can also assess how well the model is expected to explain and predict future outcomes. Thus, a high R 2 value can increase the probability of correct predictions [58]. This research model explains a substantial variant of Fintech adoption (R 2 = 0.687, Table 7), which means the brand image, Fintech perceived usefulness, user attitude, financial literacy, and user innovativeness explain 68.7% of the variation in Fintech adoption. In addition, the research model explains user innovativeness as a mediator for government support and financial literacy in Fintech adoption (R 2 = 0.345), which shows that the user innovativeness accounts for 34.5% of the variation in Fintech adoption. A complete boot-strapping procedure with 5000 samples uses to test the statistical significance of the path coefficients. Figure 2 depicts the findings of the structural model analysis.    As shown in Table 8 shows eight direct effect hypotheses and four indirect effect hypotheses. Of the eight direct effect hypotheses, five hypotheses are supported, except H1, H3a, and H8a. Brand image (H2; β = 0.19), perceived usefulness (H4; β = 0.29), attitude (H5; β = 0.32), and user innovativeness (H7; β = 0.14) have a positive and significant direct effect to Fintech adoption; thus H2, H4, H5, H6a, and H7 are supported. On the other hand, financial health, Fintech ease to use, and government support have a non-significant direct effect on Fintech adoption.
Meanwhile, Table 8 shows all indirect effects hypotheses are supported. According to these results, the indirect effect between perceived ease to use (H3b; β = 0.22) and Fintech adoption is statistically significant, although the direct effect of Fintech ease of use to Fintech adoption is not significant. This indicates that perceived usefulness fully mediates the relationship between perceived ease to use and Fintech adoption. Furthermore, government support (H8b; β = 0.02) has a positive significant indirect effect on Fintech adoption mediated by financial literacy. Also, government support (H8c; β = 0.06) has a positive significant indirect effect on Fintech adoption mediated by user innovativeness, although the direct effect of government support on Fintech adoption is not significant. This indicates that financial literacy and user innovativeness fully mediate the relationship between government support and Fintech adoption. Meanwhile, financial literacy has an indirect effect on Fintech adoption, with user innovativeness becoming a mediating variable. Note: ** and *** represent significance at 5% and 1% respectively and the t-values are given in parentheses.

Fintech Adoption in Indonesia
The purpose of this study was to empirically measure user innovativeness, attitude, brand image and financial health toward Fintech adoption during the COVID-19 crisis. To achieve this goal, social constructs from the extended hybrid framework, such as internal issues (user innovativeness, attitude, financial literacy, and financial health) and external issues (government support and brand image), were integrated into the TAM model.
Descriptive findings explain the characteristics of Indonesian society where young people under 35 years old, often referred to as millennials, dominate the experience of using Fintech. This is in line with research from Association of Indonesian Internet Service Providers [60] that explains Indonesia is experiencing relatively rapid development, with internet users reaching 73.7% of the total population of Indonesia. Fintech is considered an alternative or solution that can facilitate Indonesian people in conducting their financial transactions, especially the role of Fintech in payment transactions. The Fintech ecosystem in Indonesia is strengthened by regulation and innovation to improve service infrastructure in the field of technology. Pandemic accelerates this by forcing or pressure people who cannot interact directly must switch indirectly that is utilizing the role of technology in economic activities.
The study findings reveal that user attitude has the most significant direct impact on individuals' intention to use Fintech during crisis. These results are consistent with the results from previous studies [29,46,48]. Besides that, brand image [29,37], perceived usefulness [41,61,62], financial literacy [25,47,48], and user innovativeness [29,51,52,63] had a significant direct impact on Fintech user adoption. Surprisingly, financial health, perceived ease to use and government support did not have a direct impact on Fintech adoption, although Fintech easy to use, financial health and government support do not have a direct effect. Our findings show government support and perceived ease to use has an indirect impact on Fintech use adoption. These findings can be explained as suggesting the external factor such as government support does not have a direct effect on Fintech user adoption. Still, government and policy makers can make policies that improve the community's financial literacy and user innovativeness to increase the level of Fintech user adoption in the community, especially entrepreneurs and Micro Small Medium Enterprises (MSMEs).
Based on our findings, internal factors such as financial health do not hinder the public in using financial technology. However, in the period of the COVID-19 pandemic, the discussion revealed many people and entrepreneurs have problems in financial health. Although, direct subsidies from the government are the same as the lowest living costs make the community and entrepreneurs survive. Another finding said external factors such as brand image have contributed to elevated financial technology user adoption. Therefore, to improve the brand image of Fintech services, companies should prioritize convenience and security as an integral part of the Fintech service to encourage users' Fintech services adoption.

User Innovativeness on Fintech Adoption
Rogers [12] describes individual innovation as a person's readiness to adapt relatively faster than others, in this study with regards to Fintech adoption. Individual readiness to innovation encourage user open innovation and it correlates with openness to new experiences, creativity, leadership, and a courageous attitude in taking risks [7,64]. Previously, individual innovativeness theory was commonly applied in education research, such as to measure individual readiness to adapt to digital learning process. Innovation among people is viewed as a multi-factorial construct. Pratoom and Savatsomboon [65] describe the factors that impact individual innovation in 1526 member groups in Thailand and found creativity, self-leadership, and knowledge management having influence towards individual innovation. Recent studies by Aldahdouh et al. [66] from 315 employees at Tampere University, Finland, depicts a person's psychological factor as the main trigger for individual innovativeness. Recent studies that integrate user innovativeness with technology adoption in the financial sector were conducted by Yoon and Lim [14]. In this study, user innovativeness is integrated with the individual's willingness to find ways to operate new technology, the speed at which a person tries new technology compared to others, including the level of individual preference in conducting experiments on Fintech services as prescribed by Hu et al. [29]. Corroborating with recent findings, our study also finds that user innovativeness does significantly influence users' Fintech adoption.
This study finds that user innovation has an essential role in Fintech adoption in Indonesia. User innovation has a direct and indirect impact on user acceptance of Fintech services. The direct impact of user innovation on Fintech adoption is shown by the significant relationship between the two variables. Meanwhile, the indirect effect is shown through the role of user innovation as mediating factor for financial literacy and government support for Fintech adoption. The result is undoubtedly surprising since user innovation could indirectly benefit factors associated to users' internal knowledge of financial literacy and the external factor reflected in government support. This suggests that internal and external factors play an essential role in driving people's innovation to adapt to new technology, particularly for Fintech adoption.

Conclusions
This study is focused on Fintech adoption in Indonesia. Fintech activities in this country have developed very rapidly, both Fintech services pioneered by incumbent companies in the financial and banking industry and internet-only bank start-ups that optimize internet-based information technology as a business model. To investigate the Fintech adoption, various important technology acceptance factors are identified based on the literature, evaluated from the information that has been collected through questionnaires among Fintech users in Indonesia.
The findings crucial factors that drive Fintech adoption for Indonesian users. The variable attitude was the most significant determining factor, and on the contrary users' financial literacy contributed the least to Fintech adoption. The research findings also show that user innovativeness impacts, directly and indirectly Fintech adoption in Indonesia. It is necessary to empower the regulation and educate society since government support affect Fintech adoption through user innovativeness. Public access to the financial sector through digitization is an essential initiative for local governments to drive equality and welfare; and promote United Nation's SDG number 8, with regards access to financial services for everyone. Even though this study found that financial health does not affect the Fintech adoption, it is essential for society to embrace Fintech services. More importantly during the COVID-19 pandemic, where the interaction between human is limited.

Implications
Fintech adoption needs to be optimized through macro and micro levels. The government participates in the macro level by building infrastructure such as an internet network to provide access for users of financial services both in the rural and urban areas. The active involvement of financial industry players by providing financial products according to the community's needs is also an essential element in expanding access to formal financial services. On the micro-level, user open innovation needs to be accelerated by optimizing the use of external information to adopt the new technology [7]. Optimizing the involvement of all related parties such as governments, academics, researchers, and other stakeholders, plays a pivotal role in increasing financial literacy and inclusion index in a country.

Limitations and Recommendations
This study collected data from 458 respondents, then analyzed it to investigate the Fintech adoption in Indonesia. Currently, the respondents are only Indonesian, so the Fintech adoption with respondent from other countries could produce different result from this study. Despite the sample size of this study is relatively larger than previous research on Fintech adoption in Indonesia, the investigation only focuses on the individual level. Broader studies can be conducted with different samples, such as MSMEs, whose contribution is significant to the Indonesian economy. In addition, the adoption of Fintech that focuses on women-MSMEs also needs observation, in line with the UNSDGs number five target to promote the achievement of gender equality. The data collection process during a pandemic COVID-19 is also a challenge because researchers are unable to properly understand respondent's answers.
Future research may modify the theoretical framework of this study for other countries. This research can also be expanded by adding new dimensions such as cultural factors and the geographic location of respondents. In addition, research also needs to focus more specifically on certain Fintech services. Informed Consent Statement: Informed consent was obtained from all subjects involved in the study.
