Transaction traces analysis is a key utility for marketing, trend monitoring, and fraud detection purposes. However,\nthey can also be used for designing and verification of contextual risk management systems for card-present\ntransactions. In this paper, we presented a novel approach to collect detailed transaction traces directly from payment\nterminal. Thanks to that, it is possible to analyze each transaction step precisely, including its frequency and timing.\nWe also demonstrated our approach to analyze such data based on real-life experiment. Finally, we concluded this\npaper with important findings for designers of such a system.
