A woman from the Bernese Oberland recently asked herself this when she discovered someone else's credit card in her purse. But her customer advisor at the bank knew the answer.
One common trick used by the fraudsters is described below. Once they have watched their victim enter his or her PIN, they then barge into them so they drop their card. They pick it up for them, swapping it for another one unnoticed and give their victim the wrong card back. It is only much later, like this woman, that the victim notices the card isn't hers. In the meantime the criminals have gained ready access to the victim's account.
For this reason it is important to be careful when using your PIN and always make sure no-one can see it. Also, when withdrawing money or paying by card, don't let yourself be distracted and always be suspicious if anyone comes too near.
