the answer is: Limit how many credit cards you carry
Often times, people who carried more credit cards than they actually need would not realize if one of their credit card is missing.
This would give a lot of time for identity thief to extract various information about you and use up your missing credit card.
To avoid this, you need to limit the amount of credit card that you carry to the bare minimum and only use it on special occasions. It is much safer to use cash for payments because it minimize the chance of identity theft.
