The Novel Online Comparison Tool for Bank Charges with User-Friendly Approach

This paper presents a proposal for the novel comparison tool for bank charges; the online calculator service. The development of this tool was motivated by information asymmetry, which exists on the market of payment accounts to consumer’s disadvantage. Our calculator service provides user with the list of the most suitable bank accounts based on his preferences, sorted by monthly fee. It is up to the particular user whether he fills in values of his current usage or future requirements. The results are personalized based solely on user’s input. This paper reveals motivation behind our work and presents the current implementation of our proposal including conceptual foundation, workflows, matrix of data for underlying logic and of course user interface. By presenting workflows we stress multidimensional use of our service. Apart for clear benefit for individual user, the data acquired from all users can be used for post-processing, which includes various analyses of user behaviour and resulting user profiling regarding using bank services. The calculator service was already launched for Czech environment on https://​uni.​uhk.​cz/​kalkulator/​.
