A Systematic Literature Review About Quantitative Metrics to Evaluate Usability and Security of ATM Interfaces

Automatic Telle Machine or ATM remains one of the most used banking channels and have been transformed into complex machines, where multiple operations can be carried out, not just cash withdrawals as was at the beginning. In this context, the usability and security of interfaces become essential aspects for users to interact with ATM interfaces efficiently. About usability, several studies support its important on the user experience, which also applies to the ATM domain. About security, previous works manifest its importance especially in the ATM domain. In this sense, it is intended to utilize usability and security metrics that allow establishing the degree of usability or security of ATM interfaces. In order to identify whether there are already metrics that may be valid for evaluating ATM interfaces, the authors present a systematic literature review they made about metrics that assess usability and security in banking software. After executing the review, five relevant documents were obtained. Of these, the most significant contribution is that of 160 metrics divided into 13 categories of metrics to assess the security and usability of an Internet Banking. Future research will be focused on evaluating the relevance of these proposals in the ATM domain.
