If your credit card chip is not working due to the accumulation of some dirt on it, or in case of other similar minor reasons like stains blocking your credit card from being readable, then your card needs a cleanup. To clean your credit card, swipe it with a wet and soft piece of cloth. After that, you can use a dry cloth to remove excess water from the surface of the card. Make sure the magnetic stripe is clean and does not get smudged.
As we discussed, close contact with a magnet can damage the credit card’s magnetic stripe, which holds information and is used to communicate with the scanner. The wallets and purses with a magnet on them should not be used to store credit cards in them. If you have one, you must consider replacing it with a non-magnetic one.
If you are at a counter making a purchase and while paying the bill, you realise that the credit card is not working and cannot be used for making payment. At such times, you can ask the cashier to input card details manually in the system and use it for payment. This way, you can save yourself in a situation of stress.
The last resort is to contact your bank and request for damaged credit card replacement. If your credit card has expired, then you have no other choice but to request for issuance of a new valid credit card. In case of physical damage like demagnetisation of a credit card, you again have no choice but to request a new card.
