What we usually call "clone card", that is, "fake card", has no other bank logo and pattern except a magnetic stripe on the card surface, which is specially used for illegal cash withdrawal. There are also some "clone cards" that cover the operation information of ready-made credit cards (debit cards). Although it is no different from a normal credit card (debit card), when swiping a card on a pos machine, the bank card number displayed on the screen of the POS machine cannot be consistent with the card information.

Therefore, when merchants use POS machines to swipe their cards for customers, they should compare the information on the screen of POS machines and the card surface. If the information is different, we must resolutely prevent cardholders from swiping their cards. When citizens use bank cards on ATM and POS machines, they should observe whether the machines are abnormal and keep the bank cards and passwords properly. Once you find that your bank card has been stolen and cashed out in different places, you should report the loss to the police at the first time and keep the evidence in time.

In addition, the "chip credit card (debit card)" is more secure than the widely used "magnetic stripe credit card (credit card)", which can effectively avoid the card being copied. Conditional cardholders can change their pure magnetic stripe cards into "chip cards".
