@pourteaux The only problem with cards (from a UX point of view) is security: far too much trust required in the merchant.
A card with a confirmation screen and either biometric or PIN verification (to be done before you pay) on the card itself would be closer to ideal.
@pourteaux 卡的唯一问题（从用户体验的角度来看）是安全性：对商家需要太多的信任。
带有确认屏幕和卡本身的生物识别或 PIN 验证（在您付款前完成）的卡将更接近理想。
