TAM applied theoretical model (researched in Vietnam)

Figure 1.4: Research model of electronic banking in Vietnam
(Source: Huy and Anh, 2008)
In there:
Personal characteristics are related to perceived benefits (H1) . In the context of inequality in educational levels, especially in the IT sector of Vietnam, it is necessary to study the role of personal characteristics variables (income, age, gender).
Perceived risk is related to perceived benefit (H2), which is considered the uncertainty that customers face when they cannot measure the consequences of their usage decision.
20
Customers are influenced by the risks they perceive, whether or not they exist. Hewer and Howcroft (1999) and Howcroft et al. (2002) argue that although customers trust their banks, they have little trust in technology. In the context of Vietnam (limited technical skills, information security and electronic transaction laws, and a fear of contact with machines), this is a major obstacle to the development of e-commerce in general and the transition of business forms from traditional banking to e-banking in particular.
Autonomy is the ability of an individual to use a computer (Compeau and Higgins, 1995) and is related to perceived ease of use (H3) (Venkatesh and Davis, 1996; Igbaria and Iivari, 1995; Venkatesh, 2000; Agarwal et al., 2000). According to O'Cass and Fenech (2003), when users have enough experience with technology, they will have confidence in their ability to use the system. Vietnam's technological level is nearly half a century behind that of developed industrial countries, which partly explains the lack of technological autonomy of a large part of the Vietnamese people. Therefore, autonomy plays an important role in measuring the level of acceptance of e-banking in Vietnam, people with high computer autonomy will be more likely to use the system.
Convenience is related to perceived ease of use (H4), which is the customer's comfort with logging in/out of the system, transaction location, transaction time... Dennis and Papamatthaiou's (2003) study on online shopping motivations has shown that convenience is closely correlated with online transaction intention and convenience is also positively related to the use of online banking (Polatoglu and Ekin, 2001; Gerard and Cunningham, 2003). With the current state of unsynchronized infrastructure in Vietnam, this will be a factor that strongly affects perceived ease of use.
Perceived ease of use is related to perceived utility (H5) (Davis, 1989). These are two belief variables in the original TAM model. Users feel that the system is useful when it makes transactions faster, is easy to use, improves efficiency, etc. On the other hand, customers will not feel that the system is useful.

benefits that e-banking brings if they do not find the system easy to use.
Attitude is related to perceived ease of use (H6) and perceived benefit (H7). Accordingly, individuals will intend to use the system when they have a positive attitude and conversely will not accept the system when they have a negative attitude towards its use (Davis et al., 1989).
Intention is related to perceived benefits (H8) and attitude (H9). Individuals have intention towards a behavior when they believe it will improve their work performance. This improvement brings different benefits and affects the behavior (Davis et al., 1989). Perceived benefits are also one of the strongest variables influencing intention to use (Venkatesh and Davis, 2000).
1.2.3 Proposed model of the study:
The study uses the extended TAM model, adding a motivational variable according to the TPB model, which is social influence: the level of influence from the attitudes of relevant people on the customer's decision to use. In the proposed research model, external variables related to perceived benefits include: work, compatibility, usefulness, risk reduction; external variables related to perceived ease of use include: access and flexibility. In addition, according to the reference of some banking experts, the study also added a factor affecting the customer's decision to use, which is the cost factor. Customers decide to use Internet Banking services because it saves a lot of time and travel costs because customers do not have to go directly to the bank or service providers to pay bills for goods, electricity, water, insurance premiums, etc.

Figure 1.5: Research model of factors influencing the decision to use Internet Banking of individual customers at VCB HCM
In summary, the model proposes 8 factors influencing individual customers' decision to use Internet Banking, including: work, social influence, access, compatibility, flexibility, usefulness, risk reduction, and cost. In which:
Work has a relationship with the customer's decision to use Internet Banking. If the customer's work mainly involves transactions via the Internet, the need to make payment transactions quickly and promptly is inevitable. On the other hand, if the customer's workplace is not near the bank and the customer feels that going to the bank to make transactions takes a lot of time, the customer will choose to use Internet Banking transactions.
Social influence has a relationship with the decision to use Internet Banking of customers. The stronger the attitude of the people involved and the closer the relationship with those people involved, the more influenced the consumer's purchasing tendency is (Fishbein and Ajzen, 1975). Customers use Internet Banking because they listen to the recommendations of relatives, friends, colleagues or they use it because they see people around them also use it to fit the general trend of the times.
Access is related to the customer's decision to use Internet Banking. Customers will use the service if they know about the service's benefits because the service is widely advertised. Customers feel comfortable using the service if the service is guided clearly and easily, and the program's transaction operations such as logging in/out, payment, transfer... are performed easily and quickly.
23
Compatibility has a relationship with the customer's decision to use Internet Banking. Internet Banking service has a more limited customer base than other banking services because customers are those who have knowledge about accessing the Internet. Customers will use Internet Banking because they find it suitable for their current status, lifestyle and interests.
Flexibility is related to the decision to use Internet Banking of customers. Customers use Internet Banking because they can make transactions with the bank anywhere, anytime as long as they can access the Internet. Customers do not need to go directly to service providers to pay bills, pay insurance premiums, etc. Customers also do not need to go to the bank to wait for their turn to make a transaction, but customers can flexibly make any transaction they want on the Internet Banking program.
Usefulness is related to the customer's decision to use Internet Banking. Customers will use the service if they feel the service is useful such as: diverse services that meet the customer's needs, transactions are easy and fast. Through Internet Banking service, customers can actively control their finances effectively.
Reducing risk is related to the decision to use Internet Banking of customers. Nowadays, criminal activities are increasing in all fields, so the need to ensure the safety of assets and lives is always a top priority for customers. Transactions via Internet Banking will ensure more safety for customers because customers do not need to carry cash when paying partners and customers are guaranteed confidentiality of information when making transactions.
Cost is related to the decision of customers to use Internet Banking. Customers make transactions via Internet Banking because they save a lot of time and costs when making transactions because they do not need to go directly to the bank or service providers to pay or perform financial services, securities, etc.
