Core Viewpoint - The recent surge in card fraud incidents highlights significant vulnerabilities in the payment industry, particularly in cross-border transactions, where information asymmetry and risk control loopholes are prevalent [2][4]. Group 1: Issues Identified - Card fraud not only results in financial losses for cardholders but also exposes the information asymmetry and risk control weaknesses across various segments of the payment industry [2]. - The complexity of cross-border payments contributes to the prevalence of fraud, with incidents such as unauthorized transactions on canceled cards being more common internationally than domestically [2][3]. - The existence of information silos among issuing banks, card organizations, and acquiring institutions leads to fragmented risk control rules, making the system vulnerable to fraud [2][3]. Group 2: Technical and Regulatory Vulnerabilities - Criminals exploit the information barriers and lack of coordination between different payment system segments, resulting in a failure of the risk control system [3]. - Technical defenses are inadequate, with static card number verification being easily compromised and payment interface vulnerabilities allowing hackers to access sensitive information [3]. - Regulatory arbitrage creates a breeding ground for fraud, as varying levels of merchant scrutiny across regions can lead to weak points in the payment system [3]. Group 3: Recommendations for Improvement - To effectively address card fraud, a comprehensive security framework must be established across the entire payment chain, focusing on proactive measures [4]. - A three-dimensional model involving technology, rules, and regulation should be promoted, including the implementation of tokenization to replace static card numbers and the introduction of biometric and behavioral analysis for smarter risk control [3][4]. - Establishing international collaboration mechanisms and sharing high-risk merchant blacklists can enhance regulatory oversight and streamline cross-border legal processes [4].
