After writing it, you sent me three copies. What's different is that there is a hole? Guangfa also sent me one like that, that is, you can only swipe your card, you can't go to ATM to get cash, and there is a hole to hang it up. Generally, only one card is used. You don't have to call 95508 manually, and then give him the useless card number and ask him to cancel it. You don't need to go to the counter. You have to charge an annual fee for how many cards you have opened. Unless you swipe your card six times each.
