What You Should DoWork with companies that you know and trust.
Memorize your PIN number (Personal Identification Number) and keep printed copies of the numbers in a confidential place.
Sign all your payment cards as soon as you get them. This way when the salesperson checks the signature on the back of your card against the signature on the sales receipt, you will be protecting yourself if your card is lost or stolen.
Check your cards periodically to make sure none are missing.
Destroy and dispose of copies of receipts, airline tickets, travel itineraries and anything else that displays your card numbers
