How do I protect my credit card from magnets
A very simple way to protect a magstripe card is to put it in a paper or a plastic sleeve. You can also use a wallet-type credit card holder and keep the cards facing the same direction in order to avoid potential inflictions or scratches.

How easy is it to demagnetize a credit card
Coming into contact with refrigerator magnets, clasps on wallets, and magnets on the back of tape measures and flashlights can demagnetize a credit or debit card. When you place your card in your wallet, but sure not to rub it up against the metal clasp and place it as far away from it as possible.

Will my credit card work if I signed on the magnetic strip
Contact with magnets can essentially scramble the data on a card's magnetic strip. Once that happens, point-of-sale terminals can't “read” the card, resulting in your credit card not working. You may not see magnets in your purse or wallet, but they're a common design feature used to facilitate opening and closing.
