The TAM is a theory that explains how users come to accept and use new technology, focusing on two key factors: perceived usefulness and perceived ease of use. TAM is a behavioral/cognitive psychology model that helps understand why people adopt or resist new technologies. The model was developed by Fred Davis and Richard Begoni in 1989.

Perceived Usefulness: The extent to which a user believes that using a particular technology will help them perform their tasks better or achieve their goals.

Perceived Ease of Use: The extent to which a user believes that using a particular technology will be effortless and straightforward.

TAM posits that these two perceptions (perceived usefulness and perceived ease of use) directly influence a user’s attitude towards using the technology, which in turn affects their intention to use it, ultimately leading to actual usage behavior.

The model is widely used in information systems and other fields to predict the likelihood of technology adoption (2).

The TAM is an information systems theory that models how users come to accept and use a technology. The actual system use is the end-point where people use the technology. Behavioral intention is a factor that leads people to use the technology [Foon et al.

Association is a concept, but correlation is a measure of association and mathematical tools are provided to measure the magnitude of the association. So ease of use of Internet banking cant affect their attitude towards Internet banking.

Again in this research the author found that (Table 8) there is no remarkable association between perceived usefulness and attitude of Customers towards using Internet banking system is true. So if the customers don’t get enough usefulness through Internet banking its has on effect on the attitude of customers.

The author also found that (Table 10) there is no notable association between customer’s attitudes towards using the Internet banking system and their intention to use it is true. But the beta value (r = 0.999442235) in table reveals that there is a strong positive relationship between attitude and the intention to use internet banking of IBBL. This two opposite statement explain that customer’s attitude and their intention to use Internet banking are strongly positively correlated but customer’s aggressive attitude or politeness can’t affect their intention to use Internet banking for E-Commerce transaction.

In this research the author also found that, there is no remarkable association exists between age and customer’s intention to use an Internet banking system for E-commerce transaction is true (Table 12). So customers at different age can frequently used Internet banking service to perform E-Commerce transaction. So customers at different age can smoothly used Internet banking service.

This research also show that (Table 14) there is no notable link exists between the level of computer literacy and customer’s intention to use internet banking is true. So level of computer skill of customer’s can’t affect their intention to use Internet banking system to perform E-Commerce transaction. So very simple and basic computer skill required to perform Internet banking transaction service of Islami Bank Bangladesh Ltd.

The author showed there is a positive association that exists between perceived usefulness and attitude of customers towards internet banking service (Table 9). The research also express that there is no notable association exists between customer satisfaction and their attitude towards internet banking (Table 17). So if the customer is less satisfied by internet banking service it could not mean they use less of internet banking system.

The research also shows that there is no significant relationship between device user and their attitude towards internet banking. Access of internet banking and operating it through different device like mobile, laptop is same (Table 26).

In Table 18, the author showed that there is a positive relation that exists between customer satisfaction and attitude towards internet banking. The research also establishes that there is a significant relationship between education level and mindset of customers towards internet banking (Table 27).

In 12 Likert scale mean is greater than 3 represent a positive attitude of customers of Islami Bank Bangladesh Ltd towards Internet banking. High Standard deviation indicates there was a wide range of answers, indicating disagreement (Table 28).

In Table 21, the author represents that a positive regression exists between social impact and intention of customers towards using the internet banking system. For validity test purpose the author shows that, the content validity proved that half of the customer rated that the internet banking service is essential to perform E-Commerce related transaction (Table 29). Convergent Validity shows that the internet banking service is adequate to perform e-commerce related transaction (Table 30). In this research the discriminant validity has a negative value. For the discriminant validity purpose the author selects two criteria such as customer’s intelligence level and mind set of customer’s towards internet banking (Table 31). Here the author used Pearson r test, which gives a negative value (-0.46). So intelligence level is negatively related to the customer’s mindset.

Internet banking payment systems of IBBL still require less time for validation and payment steps. So this is very less time-consuming service.

Again electronic fund transfer (EFT) transaction through Internet banking faces some problem also, such as the clients cannot reverse the transaction if any error occurs, sometimes they may not get any confirmation message of successful EFT transaction.
