First, consider how your credit card became deactivated in the first place so you can avoid it the next time around. Credit cards become demagnetized by being around magnets of any kind. They can also lose their ability to be read after extended use or improper care. By storing your cards in a sturdy wallet, so that the strips of each card don't face each other, you can prevent your cards from becoming demagnetized.

If you need to use your card at a store before your new one comes in, there are ways to do so. First, you can put a plastic shopping bag over the entire card. When it comes time to swipe, you will need to swipe the card with the bag on. This increases the static electricity between the bag and the scanner, increasing the chances of it being read.

You can also amplify a scanner's ability to read a weak signal by licking the strip of your card. If you are not comfortable with that, simply rub a liquid across the strip before swiping.

When all else fails, the majority of credit cards can be punched in manually. If the scanner is not reading the card, a cashier should be willing to punch in the numbers. Signatures are confirmed visually, so this has no effect on security.

Don't forget the option of online shopping. Since you don't need to swipe anything when using the computer, you can shop at your leisure without having to worry about swiping your card.

Make sure you call the credit card company and make them aware of the issue. There is no way for them to know unless you inform them. They can likely send out a new card within the week if you make a simple phone call.
