Novita, they will not come to the ATM and return your card, but they can suspend your card until you re-activate to ensure there are no fraudulant withdraws. They can confirm on the telephone if your card has indeed been seized by the bank or if the machine is faulty. If it is seized by the bank for incorrect pin or waiting too long to take your card out after your transaction etc. the bank will not come to the machine as this is routine. If they find the machine was tampered with (if the transaction is logged as normal and the card is stuck) they will come, but not quickly and you have to stay there with your card.
