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

POS产生的交易跟踪作为EFT交易中风险管理系统的上下文信息源

交易跟踪分析是用于营销，趋势监视和欺诈检测目的的关键实用工具。但是，它们也可以用于设计和验证用于卡存在交易的上下文风险管理系统。在本文中，我们提出了一种新颖的方法来直接从支付终端收集详细的交易跟踪。因此，可以精确地分析每个交易步骤，包括其频率和时间。我们还演示了基于实际实验分析此类数据的方法。最后，我们以对这种系统的设计者重要的发现结束了本文。
