A Framework of Mobile Banking Adoption in India

: Mobile banking is now an important and evolving medium for executing banking transactions. It has a huge potential in a developing country such as India. Our study explores the important antecedents of the mobile banking adoption intention of Indian customers and proposes a comprehensive framework by extending the traditional technology acceptance model (TAM). Along with the two constructs provided by TAM, four customer-oriented constructs have also been measured for this purpose. The conceptual model has been veriﬁed empirically, with the data mobilized with the help of a survey from 203 future mobile banking service users. The structural equation modeling (SEM) technique has been undertaken to establish the e ﬀ ect of the antecedents on mobile banking adoption intention. The results demonstrate that, together with the constructs of TAM, viz. perceived usefulness and perceived ease of use, as well as all other relevant behavioral factors, namely subjective norms, personal innovativeness, trust, and self-e ﬃ cacy have exerted a statistically signiﬁcant positive e ﬀ ect on the mobile banking adoption intention of customers. The study provides an empirical foundation, which can be useful to banking and mobile services by helping companies to formulate their marketing strategies.


Introduction
The impact of technology is widespread in our life, and it is impossible to visualize a life devoid of it. Innovations happening across the globe in different fields have made our life very relaxed and effortless. The diffusion of technology is very deep and brisk in every walk of our life, e.g., the growth of the telecom sector has been enormous in every part of the globe, including all developed and developing nations such as India. As reported by the Telecom Regulatory Authority of India (TRAI), the number of mobile subscribers in India increased from 1186.63 million in June 2019 to 1195.24 million in September 2019, with a growth of 0.73% over the previous quarter (Source: Indian Telecom Services Performance Indicator Report, July to September 2019 of TRAI). This swift and indiscriminate growth of technology has led service providers to hunt for new ways of reaching their customers. The traditional modes of buying and selling have also witnessed a turnaround under the influence of technology. The application of mobile technology is very applicable in all types of business transactions, and banking and financial services are not immune to this. The brisk expansion and popularity of online buying have stimulated banks and financial sector companies to motivate their clients to go for online and mobile banking modes for making payments and other related banking transactions. Besides this, the escalation of mobile banking can be ascribed to the multiplicity of problems faced by customers in accessing financial services with the help of existing modes of delivery [1]. Mobile banking in the noticeably The next part of our study analyzes past empirical studies for exploring the important determinants of mobile banking adoption intention of customers in the different regional, social, cultural, and economic environments. The methodology of the manuscript is discussed in the next section to it, which is furthered by empirical investigation and elucidation of the data. The last part of our paper presents the conclusions of our study and its practical implications for managers, government, academicians, researchers, and the common public, along with the limitations and prospects for auxiliary research in this area.

Models Used in Technology Adoption
The study of user response to a novelty or technical development is a significant issue of investigation in this era of innovation. It has been studied by many researchers from a variety of theoretical perspectives. Some of the well-known theoretical models exploring the factors responsible for technology acceptance by users include Innovation diffusion (DOI), technology acceptance model (TAM), the theory of planned behavior (TPB), the theory of social cognition (SCT), hybrid models of TAM-TPB, and unified theory of acceptance and use of technology (UTAUT), etc. (See Table 1).  (1975,1980) [17,18] These theoretical approaches have been empirically verified in many research pursuits aimed at explaining user behavior and intention towards acceptance of new knowledge. Amongst these theories, TAM is the most sought after [19,20]. It has been verified in varied contexts in the realm of technology [21] innovation [22], online business [23], social media [24], e-learning [25], and online or mobile banking [8,26,27]. The importance of TAM is due to its parsimony, verifiability, and generalizability. On the contrary, [28] in his study argues that TAM does not reliably explain the users' behavior about buying, disposing of, and usage of technology. Therefore, it might not be falsifiable. Also, it is not completely capable to clarify users' acceptance and exercise of new technology concerning e-government [29]. As per TAM, a user's technology usage is decided by his/her behavioral intent, which is a function of users' perception of usefulness (the belief that the usage of knowledge will make their job better) and perception about the simplicity of use (i.e., use of knowledge will be straightforward).
TAM has been expanded and customized in numerous ways in several papers such as UTAUT [13], TAM+ [30], TAM 2, and TAM 2+ [31]. TAM+ model emphasizes that attitude to use technology is dependent on perceived usefulness, perceived threat (social and performance), which further affects the intent to use the technology. The important drivers of the UTAUT approach are performance and efforts anticipation, societal control, and facilitation environment. IDT, another important theory, answers why in which manner and at what intensity new technology is acknowledged by different cultures and societies for which contextual research is a critical input [32].
Many empirical studies on electronic banking and mobile banking have applied TAM [20], UTAUT [33,34], TPB [35], IDT [36], TTF [37], TAM+ [38], and UTUAT2 [39] for identifying the important drivers having a bearing on the mobile banking adoption intention of users. A few other studies have also used demographic variables along with the behavioral factors as drivers of technology adoption intention [40,41]. Most of these studies have been limited to economically and socially advanced economies [4,5,30,37,42], but the same is catching up now in emerging economies [40,41,[43][44][45]. Few mentionable studies in India on the topic include [9,38,39]. A synoptic view of the prominent study is presented in Table 2 given below.

Conceptual Model
An insight into the literature has helped us in determining important constructs influencing the mobile banking adoption intention of users in different parts of the world. These constructs, as identified, have been used to understand the intent of the Indian public to make use of mobile banking. The identified constructs for our study encompass self-efficacy (SE), personal innovativeness (PI), subjective norms (SN), perceived ease of use (PEOU), perceived usefulness (PU), trust (TRU), and mobile banking adoption intention (MBAI) [9,43,48,50]. Figure 1 depicts the proposed conceptual model, which is a modification of the TAM 2 model. Our model identifies six antecedents of mobile banking adoption intention of customers and two each of perceived ease of use and perceived usefulness. The first six antecedents are self-efficacy, personal innovativeness, subjective norms, perceived ease of use, perceived usefulness, and trust. The two antecedents of perceived ease of use are self-efficacy and personal innovativeness, and the precursors of perceived usefulness are personal innovativeness and subjective norms. All constructs, along with the theoretical doctrines and the hypotheses, are explained in the next sections.

The two antecedents of perceived ease of use are self-efficacy and personal innovativeness, and the precursors of perceived usefulness are personal innovativeness and subjective norms. All constructs, along with the theoretical doctrines and the hypotheses, are explained in the next sections.
2.1.1. Self-Efficacy (SE) SE can be considered as "one's belief in one's ability to succeed in specific situations or accomplish a task." Theory of social cognition (SCT) defines it as people's assessment of their capabilities or efficacy to execute an assigned task efficiently; it is not connected to the skills of a person but to how the person uses these skills and faith in such skills. In many studies, it has been observed that SE significantly influences the intent to use and perceived ease of use of new technology [50,51]. Based on the findings of these studies, we propose the following hypothesis.
Hypothesis 1a (H1a).Self-efficacy has a positive effect on perceived ease of use. Hypothesis 1b (H1b). Self-efficacy has a positive effect on mobile banking adoption intention.  2.1.1.

Based on the findings of these studies, we propose the following hypothesis.
Hypothesis 1a (H1a). Self-efficacy has a positive effect on perceived ease of use.
Hypothesis 1b (H1b). Self-efficacy has a positive effect on mobile banking adoption intention.

Personal Innovativeness (PI)
The success of a technological innovation hinges on individuals' differences besides other determinants. Due to their differences in innovativeness, the reaction of people is also observed to be different while dealing with a technology [52,53]. Personal innovativeness is the readiness of a person to seek new technology [54]. A generic model of TAM does not consider the impact of personal innovativeness on adoption intention; however, it was used as an additional construct in the study by Agrawal and Prasad (1998) [54], which reported a moderating effect of personal innovativeness on the antecedents of individual perception about the technology, perceived ease of use, and perceived usefulness. Many other studies, too, have empirically examined this construct and stated that customers with a higher degree of personal innovativeness are more willing to try new, cutting-edge innovations [55][56][57][58]. It exercises a positive impact on the usefulness and desire for technology adoption [55]. After reviewing the past studies, the following hypotheses have been proposed.
Hypothesis 2a (H2a). Personal innovativeness has a positive effect on perceived ease of use.
Hypothesis 2b (H2b). Personal innovativeness has a positive effect on perceived usefulness.
Hypothesis 2c (H2c). Personal innovativeness has a positive effect on mobile banking adoption intention.

Subjective Norms (SN)
Subjective norms as a proxy for social influence have been extracted from a theoretical model such as TRA, TPB, TAM2, and C-TAM-TPB, etc. Social influence is also known as peer influence or social influence. The subjective norm is a potent factor that explains the impact of social influence on a person's behavior [10]. It is because of subjective norms that people may use a technology to abide by others instead of their own feelings and faiths [59]. It is reported as a significant factor in predicting the intent of a customer towards mobile banking in quite many studies [60]. The following hypothesis has thus been proposed: Hypothesis 3a (H3a). Subjective norms have a positive effect on perceived usefulness.
Hypothesis 3b (H3b). Subjective norms have a positive effect on mobile banking adoption intention.

Perceived Ease of Use (PEOU)
Perceived ease of use is an essential construct of the original TAM model. It is considered as the belief of a person that the use of technology will be easier [10,26]. The construct of perceived ease of use has been used in many studies [9,27,44,48]. The empirical results of these studies suggest that PEOU has a favorable effect on the intent to approve mobile banking [44,48]. Accordingly, the following hypothesis has been developed: Hypothesis 4 (H4). Perceived ease of use has a positive effect on mobile banking adoption intention.

Perceived Usefulness (PU)
The construct of perceived usefulness has been taken from the original TAM theory. It is a hypothesis that the use of innovation will result in better execution [10]. It exerts a significant influence on the embracement of new technology by users [9,44,61]. It has been employed in loads of studies in various countries. In most of these studies, there is a common observation that perceived usefulness results in a favorable outcome on users' attitudes for acceptance of new knowledge or technology [62] in Jordan; [63] in Taiwan; [59] in Saudi Arabia; [50] in India).

Hypothesis 5 (H5).
Perceived usefulness has a positive effect on mobile banking adoption intention.

Trust (TRU)
"Trust is at the heart of all kinds of relationships" [64], which is a crucial determinant of adoption intention of mobile banking [65] and numerous other fintech services [66]. It determines users' expectations from their service providers [57]. It helps in resolving uncertainty about the motives, intentions, and prospective actions of other persons on whom they are reliant [67]. It also helps in saving on money and reduces the multiplicity of efforts [9]. Users' trust in the confidentiality and safety features of mobile banking services by banks increases the acceptance rate of mobile banking [43,65,68]. Kwateng, Atiemo, and Appiah [69] also stated in their study on mobile banking acceptance and use in Ghana that trust along with habit and price value is a critical determinant of adoption intention and usage of mobile banking. In our model, we have used the construct of trust for examining its impact on mobile banking adoption intention of customers as an extension of TAM.
Hypothesis 6 (H6). Trust has a significant effect on mobile banking adoption intention.

Mobile Banking Adoption Intention (MBAI)
Adoption is a sort of judgment regarding making optimum use of technical development. Intention, implementation, satisfaction, and utilization have been taken as a proxy for it, as extracted from literature. Behavioral intention to adopt technology has been used in a large number of empirical studies in the literature [20,30,31,38,43,50]. In our research, we have taken MBAI as an endogenous variable from the TAM, which is affected by all the constructs as mentioned above (see model, for detail).

Research Methodology
A structured questionnaire was used to measure the constructs that affect mobile banking adoption intention. The first section of our questionnaire seeks demographic details and contains filtering questions. The demographic details sought are gender, age, qualification, marital status, and region, while the filtering questions are whether having a bank account, using a smart mobile phone, and mobile banking, if yes, then duration. The second part of the questionnaire measures the constructs identified from literature and included in the model, i.e., self-efficacy [54,70], personal innovativeness [54,70,71], subjective norms [17,70,72], perceived ease of use [10,70], perceived usefulness [10,56,70], trust [70,73], and mobile banking adoption intention [56,70]. The constructs used in the questionnaire, along with their sources, are mentioned in Appendix A. These constructs were measured on a 5-point Likert scale (where 1 means strongly disagree, and 5 means strongly agree). The scale thus adapted was tested for its reliability and validity by applying suitable tests. The measurement and structural models were tested using Smart PLS software. The respondents for the study were chosen from the Delhi-NCR region. The Delhi-NCR region represents the entire Indian population, as people from all over India come here to study and do jobs. Users of mobile banking were excluded from the study as perception differs in the pre-and post-purchase phases. Customers having an operational bank account in scheduled commercial banks and using the smart mobile phone for more than one year were asked to fill out the questionnaire. In the absence of a sampling frame of nonusers of mobile banking, the present study used the convenience, nonprobability sampling approach.
A total of 379 questionnaires were distributed through a combination of the online and offline mode, of which we received a successful response from 203 respondents. Responses were solicited from the people who have a bank account and use mobile phones but do not use mobile phones for banking transactions. These people are already using technology for different purposes. They may have also developed some degree of comfort, which might influence them to use mobile phones for doing banking transactions in the future. The responses were collected between the period from August 2019 to November 2019. Necessary approvals for collecting the data from the customers coming to the bank were taken in advance from the branch managers of the respective banks. On our request, 115 customers filled out the questionnaires in the face-to-face interaction, and those who could not spare time were requested to share their responses online. However, out of 264 questionnaires sent through email, 104 completed questionnaires were received. Out of these 104 questionnaires, 88 were filled out correctly, and 16 were partially filled out. Therefore, these were not included in the study.

Demographic Analysis
Our study included 203 respondents. The demographic details of the respondents are presented in Table 3. A look into this table reveals that 74.4% of the respondents are male, and 25.6% are female. Most of our respondents (62.1%) are from the age group of 18-35 years. About the educational background of the respondents, 55.2% of the respondents are graduates, 36.9% are postgraduate, and only 7.9% of the respondents are intermediate pass.

Data Analysis
The internal consistency of the statements used in the study for the chosen constructs was verified with the help of Cronbach's alpha. Further, we extracted the convergent and discriminant validity of the data mobilized. The study makes use of confirmatory factor analysis (CFA) for extracting cross-loadings on dormant construct and followed by structural equation modeling (SEM) to ascertain significant associations among constructs included in the study.

Reliability and Validity Analysis
For the assessment of a model, it is imperative to measure its reliability, which is an essential measure for the appraisal of a model. In our study, we computed Cronbach's alpha for establishing the consistency of the constructs. The value of Cronbach's alpha is greater than 0.827 for all the seven constructs used in our model (see Table 4), which is a good indicator of reliability, as per literature [74].
Further, the value of average variance extracted (AVE) is higher than 0.71, and the coefficient of composite reliability is greater than 0.89 for all the constructs, which reflect good convergent validity [75]. For assessing the discriminant validity of the model, the square roots of AVE should be higher than the coefficient of correlation between the constructs. In our study, the second root of AVE for all the constructs is higher than the values of correlation coefficients between the constructs, which is a good indicator of the discriminant validity (see Table 5). From this, we may draw an inference that our model is reliable and valid for further analysis.

Assessment of Structural Fit of the Model
The results of the structural model (see Figure 2) showcase that our model is an excellent fit, as reflected by values of the model fit indices and residual value ) (refer to than the coefficient of correlation between the constructs. In our study, the second root of AVE for all the constructs is higher than the values of correlation coefficients between the constructs, which is a good indicator of the discriminant validity (see Table 5). From this, we may draw an inference that our model is reliable and valid for further analysis.

Assessment of Structural Fit of the Model
The results of the structural model (see Figure 2) showcase that our model is an excellent fit, as reflected by values of the model fit indices and residual value ) (refer to Table 6) [76].    The primary criterion for the assessment of a structural model is the variance explained by it [77]. In our model, the value of the coefficient of determination or variance extracted (R 2 ) is 0.711, which suggests that 71.1% of variations in the endogenous variable (MBAI) can be ascertained with the help of chosen exogenous variables. The values of path coefficients are significant for 8 out of 10 relationships (please refer to Table 7). The results of our study reflect that trust, perceived usefulness, perceived ease of use, subjective norms, and personal innovativeness have a statistically important positive effect over the dependent variable mobile banking adoption intention in this order, respectively. However, the impact of self-efficacy on mobile banking adoption intention is not observed to be significant. Further, perceived ease of use exerts a statistically significant favorable impact on self-efficacy, but the effect of personal innovation on perceived ease of use and perceived usefulness is not statistically significant. Lastly, it can also be observed that subjective norms exercise a considerable favorable effect on perceived usefulness.
The outcome of all hypotheses based on the standardized estimates and t-statistics of different paths in the model is presented in Table 8, which demonstrates that our results have supported 8 out 10 of the hypotheses. Table 8. Results of Hypotheses Testing.

Hypothesis Supported
H1a: Self-efficacy has a positive effect on perceived ease of use.  Table 8. Cont.

Discussion
The study observes a positive effect of self-efficacy on perceived ease of use, which is in harmony with the earlier studies [78][79][80]. The hypothesis of the direct positive impact of self-efficacy over mobile banking adoption intention could not be established, but it has a significant effect through the mediating variable perceived ease of use. Amongst all the exogenous variables, trust exerts the maximum impact on adoption intention followed by subjective norms, personal innovation, and perceived usefulness. The results of our study are in harmony with many studies in the area of behavioral adoption intention of new technology. Trust has been reported as an instrumental factor in many empirical studies, as it reduces the perceived risk associated with technology and creates a positive attitude towards it [70,81]. Another reason that trust exerts a significant effect on adoption intention is that customers have faith in their banks and consider them as their custodian. These results are consistent with many empirical studies [2,38] but not in agreement with the findings of Singh and Srivastava [50]. Perceived usefulness has been reported as an important variable affecting the adoption intention in many studies [56,70]. The inference drawn from these studies is that users have a positive intention towards a technology which they perceive useful. Perceived ease of use also has been reported as an important factor in mobile banking adoption intention in many studies [70,82,83]. It leads to the conclusion that users espouse a new technology when they find it relatively easy to use. However, the results of the significant positive effect of personal innovativeness and insignificant effect of self-efficacy over mobile banking adoption intention is not consistent with the findings of [70] and [51], respectively, for these two variables. The reason which may be attributed to these results is that consumers perceive mobile banking as different from other technologies, and other modes of banking are equally efficient. The value of R 2 , which indicates the explanatory power of independent variables in explaining the changes in the dependent variable (mobile banking adoption intention in our case), is also very robust at 71.1%, which is better than most of the studies on this topic [84,85].

Conclusions and Implications
Since the demonetization initiative of the Government of India of 2016, a swift rise in online banking and mobile banking transactions has been witnessed in India. The government has also taken several measures to encourage cashless payment and branchless banking to increase the efficiency of the banking system. Besides this complexity of life, rapid urbanization, growing traffic on roads, and busy lifestyles have also led to the growth of mobile banking in India. Banks and other intermediaries involved in online banking transactions are also considering this growing interest of users in online banking as an opportunity to reach their customers and provide them with a safe and pleasant mobile banking experience. Though mobile banking technology is expanding across the globe, factors responsible for its expansion and growth are not uniform in different countries. Therefore, it becomes necessary to explore the factors affecting the mobile banking adoption intention of people in India. Despite a large number of studies, the need for comprehensive research aiming at developing a model explaining the factors responsible for mobile banking adoption intention of an individual was felt. To fulfill this gulf, an all-inclusive model has been evolved to identify the forces affecting mobile banking adoption intention of customers in India. The findings of our study demonstrate that personal innovativeness, perceived ease of use, perceived usefulness, trust, and subjective norms have a remarkable effect on mobile banking adoption intention, except for self-efficacy. Findings further demonstrate that self-efficacy and personal innovativeness exert a statistically significant effect on perceived ease of use. Also, personal innovativeness and subjective norms, too, are important drivers of perceived usefulness. Trust has been observed as the most critical determinant of mobile banking adoption intention of users, followed by subjective norms, personal innovativeness, and perceived usefulness.
The study is novel and further extends the traditional technology adoption and technology diffusion models, thus making a significant theoretical contribution to the literature. This study provides meaningful information about the factors affecting mobile banking adoption in India. These factors have been considered independently in different studies but have not been examined collectively in any of the previous studies, which makes our study very rigorous. By specifying these relationships, it addresses a significant gap in adoption research. Despite using the traditional models of technology adoption and diffusion, our study endeavors to customize the model precisely for mobile banking adoption intention.
The empirical results of our study provide a valuable foundation to future researchers for the expansion and validation of our model in other developing countries.
The proposed model of our study has important managerial implications for the banking and mobile companies in formulating their marketing strategies as per the users' requirements to expand the penetration of their services. Our model explicitly specifies the critical factors (e.g., trust, perceived usefulness, subjective norms, perceived ease of use, etc.) affecting the mobile banking adoption intention of customers, which can be extremely useful for managers while devising mobile banking service strategies. As per our study, trust is the most significant antecedent of mobile banking adoption intention. Therefore, measures can be taken to build and manage the belief formation of customers in mobile banking technology. Banks, along with other intermediaries, should also make efforts to increase the general public awareness about the uses, utility, convenience, and other related benefits offered by mobile banking. These entities may devise campaigns to allay the fears of customers about the potential risks involved with mobile banking and make them more educated about the benefits of mobile banking.
The results of our study are also useful to regulators in implementing their policies regarding financial inclusion and the digital economy. This can be realized by creating a favorable financial environment conducive to the use of mobile banking technology and by formulating strategies to build the trust of people and create awareness about the use of it.

Limitations and Future Directions
There are a few limitations of our study, which we would like to acknowledge. It does not explore the impact of moderating variables such as risk associated with technology, availability of alternative modes, compatibility, quality of the mobile interface, and demographic variables, which might predict usage more accurately. The demographic variables such as gender, age, and occupation have not been considered in the theoretical model and structural model. The study uses a convenience sample, which may not be a remarkably effective method of representing the target population. The size of the sample is relatively small; therefore, the results of the study must be interpreted with caution while drawing generalizations.
This study shows several directions for future research. The results of our study can be tested and verified for other developing countries having a similar social and demographic structure as that of India, e.g., Indonesia, Malaysia, Sri Lanka, Bangladesh, Pakistan, Brazil, China, etc., as well for improved understanding of mobile banking adoption behavior of users. Future research can also be conducted to re-examine and validate the theoretical model empirically. Conceptual and empirical studies in the future may also consider a few other factors such as mobile service quality, technological readiness, compatibility, risks of technology, and inspect their association with mobile banking adoption intention of customers. Since our study focuses more on behavioral constructs such as perceived usefulness, perceived ease of use, and trust, etc., of mobile banking adoption intention, future research may include the constructs which involve monetary transactions. Besides this, future research can also measure the impact of demographic variables on the mobile banking adoption intention as mediating variables. Finally, a longitudinal research design can be used in future studies to get a better understanding of the causality and the cross-relationship among the variables.
