Credit cards have been transferred by others many times, which can be considered as stolen credit cards. There are usually two situations in which credit cards are stolen: one is that criminals directly use the original card to swipe their cards or withdraw cash. This situation is mostly because cardholders have lost their credit cards and leaked their passwords. The other is that criminals copy and forge credit cards, steal passwords and steal them in different places or online.
