Whether it is a credit card or a debit card, all bank cards are swallowed at ATM machines for the following three reasons:

First, the cardholder made mistakes in operation, such as failing to take the card over time and forcibly inserting the card;

The second is to swallow abnormal cards according to the requirements of the issuing bank, such as lost cards, stolen cards, fake cards and so on.

Third, ATM machine or system failure.
