JCB Adopts 'MiMORiTH™', a Credit Card Fraud Prevention Platform Provided by NTT Data

JCB Co., Ltd. (JCB) and NTT Data Corporation (NTT Data) are advancing initiatives to prevent credit card fraud. On March 23, 2026, NTT Data launched 'MiMORiTH™' (hereinafter 'the Service'), an information utilization platform that enables proactive measures against credit card fraud. JCB has adopted the Service as its first user to enhance its response to fraud damage. By utilizing this service, financial institutions, including card companies, can identify signs of fraud early and take action to reduce risks before damage occurs, while complementing existing measures. [Background] According to the Japan Consumer Credit Association, credit card fraud losses have remained at a high level, exceeding 50 billion yen since 2023, with unauthorized use of card numbers accounting for 90% of cases. In this environment, card companies are under greater pressure to detect fraud early and prevent damage. JCB has implemented measures such as identity verification and monitoring, but as fraud becomes more sophisticated, there is a growing need to identify risk signals before fraud manifests. NTT Data released MiMORiTH to organize and analyze various information related to fraud. JCB, agreeing with the goal of contributing to the entire industry, became the first user. [Overview of MiMORiTH] MiMORiTH organizes and analyzes fraud-related information, allowing financial institutions to cross-reference it with their own data. This enables faster and more appropriate decision-making, reducing fraud and customer support burdens. The service is operated under strict security measures and can be introduced without significantly changing existing business processes. [Future Outlook] NTT Data and JCB will continue to strengthen their efforts to build a reliable transaction environment. NTT Data plans to expand the service to the entire financial industry, including banking, securities, and insurance.
