There are currently two types of China UnionPay mobile payment, one is UnionPay SD card, and the other is swipe card head, brand: Karefu.

The payment security control is to protect the information entered by the user and prevent Trojan programs from intercepting account passwords, bank card information and other keyboard or soft keystroke records.

The control encryption of the payment system generally performs multiple encryption on the user's key information based on SSL encrypted transmission, which is relatively safe.
