Automated payment machine (APM) or Cash-in machine is one of the latest payment technologies in the Philippines which allow customers to place their cash in the machine to pay for their bills. This study focuses on three aspects of APMs – (1) evaluation of the machine dimensions, (2) usability testing of machine interface, and (3) assessment of the environment. Filipino anthropometric measurements were used to determine if the dimensions of the machine match the physical attributes of the target users. Based on the result, the current machine dimension is suitable to its users. Five respondents were randomly chosen to partake in the usability testing. Among the usability parameters, readability received the highest rating. Most users agreed that the font size and face of the text are readable and that the words can be distinguished from the background, however, one test subject felt otherwise. Difficulty to manipulate the machine and proceed with the transaction after an error and environment issues are some of the problems reported by the subjects. As for the assessment of the environment, users feel uneasy upon public display of information. In addition, cramped surrounding makes payment uncomfortable. Recommendations were made to increase the satisfaction of users with the automated payment machines.
