Can the bank card chip still be used after being scratched with a knife?

Whether the bank card chip can still be used after being scratched with a knife depends on the damage. If there are only shallow surface scratches, under normal circumstances, you may still be able to continue using it. However, if the scratches are deep and damage the inside of the chip, it may become unusable. For specific verification methods, you can go to the counter of the bank business department where the card belongs to handle a deposit and withdrawal business. If it can be handled normally, you can continue to use it. Otherwise, you can only apply for a new card.
