Clone card, duplicate card: The card after the bank card is cloned is the bank clone card.

Compared with traditional magnetic stripe cards, the main feature of chip cards is that they are difficult to clone. However, if they are really cloned, the cloned card will become a "real card" for the ATM machine. Difficult to tell authenticity.

The ATM cannot determine which card was sent. It mainly relies on the password entered by the customer for verification. In the eyes of the ATM machine, no matter what the appearance of the card is, as long as it can read the magnetic stripe Card number content, and then enter the password to operate. As far as the machine is concerned, there is no difference between the cloned card and the real card.
