How to Fix a Demagnetized Card

A demagnetized card is a credit, debit, or ATM card that has lost its magnetic strip due to damage. This can be caused by exposing the card to extreme heat and cold. However, it’s also possible for this problem to happen due to physical contact with magnets.

How to Fix a Demagnetized Card

If you notice your cards are not working right away, take them out from any old purses or wallets before inserting them into new ones. For example, if the wallet was exposed to high temperatures like those found in an oven, it will cause problems when giving the items back. Today I am going to discuss a process on how to fix a demagnetized card. So let us get started.

A Process on How to Fix a Demagnetized Card

  • First, we need to find out what caused the card to be demagnetized. Was it because of a magnetic field? Is it due to age? Whatever the case may be, this is important to figure out how exactly you can make your card work again.
  • Next, wipe off any dirt and debris that could have been on or near the card before proceeding with fixing it. If there are metal objects around (such as keys), try not to place them too close for fear of making things worse!
  • Afterwards, take an old credit card or debit card and insert one edge into the slot where you would normally swipe your finger across – but don’t go all the way in! Instead, leave the card hanging out of the slot for a few seconds before pulling it back out. If you feel anything move, then that means there might be hope to fixing your item!
  • The next step would be putting the card back into its normal position and swiping it to find any magnetic field interference. For example: if you were standing too close while holding the credit or debit card, this could have caused problems with your device as well. Try moving further away from where the potential interference is coming from and try swiping again after doing so – maybe even asking someone else at work/home who isn’t nearby to swipe instead?
  • You may also need to get rid of all metal objects around (except for other cards) and try swiping again. For example, if you were wearing your belt with a bunch of metal on it and placed the card close to that area – this could have caused interference as well!
  • If all else fails, then there is even hope for fixing your item by demagnetizing it to make sure the magnetic field isn’t interfering anymore. The last resort would be finding a hardware store nearby or taking an old refrigerator magnet home so that you can use one (or more) magnets from inside of them instead. Then, place the credit/debit card next to these items until they are no longer moving around when being held up against each other before removing them apart again!

Why Cards Get Demagnetized?

The most obvious explanation is that they have been exposed to magnetic fields, causing the tiny particles of iron oxide in them to become magnetized. Even though cards are usually shielded by plastic and paper from outside sources, a card can be demagnetized when close to other magnets or even electric motors that use electromagnetic forces such as loudspeakers.

Inexpensive speakers with permanent magnets can also cause problems if near credit cards because their own magnetic field may affect the data on your card. So always try not to keep your wallet near these types of devices!

Disadvantages of Demagnetized Cards

  • You can’t rely on card readers to read your information.
  • You might not be able to use the credit card machine at a gas station or store because of the magnetic stripe. So you’ll need cash in that case, which is inconvenient if you don’t have any nearby, and it may take some time before you find an ATM with available funds for a withdrawal.
  • If someone steals your wallet, they will be aware of all your cards’ numbers and security codes (if the card has one), so nothing stops them from making purchases without being caught, whereas these details are often required when using cash. A thief could easily buy expensive items like airplane tickets or designer clothing without tracing where the money has gone.
  • Magnetic stripes on cards are the same as a piece of iron that is easily attracted to magnets, so when you place it near a magnet (or another magnetic card), such as those in your wallet or purse, the information can be transferred and used by anyone with access to the stripe.

Key Considerations While Fixing a Demagnetized Card

  • Verify the card is demagnetized by running a magnet over it and seeing if any magnetic fields are still detected. It may be possible to run a strong magnet underneath the cabinet or under your desk that could have been enough to demagnetize your credit cards, cash, etc., without you even realizing it!
Key Considerations While Fixing a Demagnetized Card
  • If the card is demagnetized, you can use a strong magnet to reverse the effects. The magnets will only need to be held where these magnetic fields are detected for about two minutes (although some people have found it takes less time). This should fix any issue with cards not working in keycard readers and other machines that rely on magnetic strip information encoded onto credit cards.
  • After fixing your card(s), make sure to test them out before going back into circulation! If they still don’t work after running them through an ATM or using them at a store register, see if there’s anything else you could’ve done wrong during the process of reversing their magnetic field.

Final Thoughts

If your card is demagnetized, you can fix it by following the instructions in this article. The next thing to do after fixing the card will depend on how many times you have used it since it was replaced with a new one. If your company has purchased a large number of cards and only half are lost or damaged, then be sure to replace all of them at once so that they don’t happen again. This way, even if you lose another one, there won’t be any chance of someone else using yours for fraud purposes because it’s not registered as unique anymore!
