This paper aims to explore and understand the factors that affect the internet banking adoption among postgraduate’ students in International Islamic University Malaysia (IIUM).Approach- Semi-structured interviews with eight informants; four adopters and four non-adopters on postgraduate’ students were conducted to explore this issue. The results revealed that adopters and non-adopters realized that internet banking (IB) has several benefits and conveniences. However, non adopters were concerned about some factors like trust, ease of use, awareness and security. The results also showed that adopters had positive influence on use of online banking and they did not have problems with these factors because they had sufficient knowledge and experience in using online banking. This study has several limitations such as the sample used for the study was from a specific group of respondents in Malaysia (postgraduate’ students at IIUM). The second limitation was that informants were postgraduate ’students who had limitation on banking transactions. The findings are important to enable bank executives to have a better understanding of clients’ perception to adopt internet banking. This will help banks’ managers and owners formulate strategies that could significantly affect IBA among their customers.
