Paygent Inc. (Headquarters: Shibuya-ku, Tokyo; President and CEO: Junichi Suzuki; hereinafter "Paygent"), has supported EC merchants in balancing "enhanced security" and "providing a comfortable purchasing experience (sales expansion)" through the expansion of diverse payment methods and the provision of AI fraud detection solutions. Now, in collaboration with YTGATE Inc. (Headquarters: Chuo-ku, Tokyo; President and CEO: Yutaro Takahashi; hereinafter "YTGATE"), which provides EC payment optimization and fraud countermeasure support, Paygent will begin offering "YTGuard," a cart abandonment prevention service for EC merchants. This service will be provided by Paygent to EC merchants as one of the service lineups of "ADAPTIS" (Note 1), an EC merchant payment service brand developed by the NTT DATA Group, including Paygent. Through this collaboration, EC merchants who introduce "YTGuard" will be able to seamlessly achieve a reduction in cart abandonment rates for end-users, an improvement in customer experience, and the maximization of sales (profits) for EC merchants. Note 1: ADAPTIS is a payment service brand for merchants that provides end-to-end solutions for customer challenges, from in-store and online payments to streamlining payment-related operations. * "ADAPTIS" is a registered trademark of NTT DATA Corporation in Japan. * Other product names, company names, and organization names are trademarks or registered trademarks of their respective companies. Background and Objectives In recent years, with the expansion of the EC market, credit card fraud damage has been rapidly increasing, and security measures on EC sites, such as the mandatory implementation of 3D Secure, are being strengthened. On the other hand, due to these measures, "payment failures for legitimate users (so-called 'false positives')" and "cart abandonment (lost sales)" caused by unclear error messages during payment failures are resulting in significant lost opportunities for EC merchants.
