UnionPayアプリ：安全なグローバル決済とスマートカード管理

概要

This mobile app receives overwhelmingly negative feedback, largely due to significant difficulties with registration and verification processes, including issues with SMS verification codes and failed face recognition. Users frequently report problems with payment functionality, such as card binding failures and geographical restrictions limiting its use outside mainland China or with certain international cards. Performance and stability are also critical issues, with complaints about lag, network congestion, black screens post-update, and a regression in card management in a recent version. While a few users appreciate the app's convenience for managing multiple bank cards and offering free transfers, these positive aspects are overshadowed by widespread usability and functional problems.
