Hello! The reasons why China Merchants Bank's credit card can't be used are: exceeding the trading limit on the trading day, POS machine failure, card damage, etc. If other customers can use the device, the card may be damaged or demagnetized. Please change the device and try again. If the transaction limit is exceeded, please open the popular version of personal banking on the home page/right side of China Merchants Bank, select credit card login, and set the limit in Card Management-Card Limit Adjustment. If it is damaged, it is recommended that you call 4008205555 to apply for card replacement manually.

If you still have questions, I suggest you solve the credit card problem anytime and anywhere through the credit card intelligent service platform. Click here to view details > & gt/Common/Default.aspx? pageid=zxkf 1
