1. change a new magnetic card. Take the degaussed credit card directly and go to the bank to change the card in time, or call the 24-hour customer service hotline of the credit card center to apply for a new card, but it should be noted that changing the card will also change the card number.

2. magnetizing. Consult degaussed credit card issuers to see if they can replenish magnetism. Some banks can replenish magnetism, and credit cards that replenish magnetism do not need to change their card numbers.

3. Replace the IC card. Unlike magnetic stripe cards, IC cards are not afraid of degaussing, because IC cards rely on the integrated circuit in the card to store information, while magnetic cards rely on magnetic force to record information. Compared with magnetic cards, IC cards have better confidentiality, and you don't have to worry about degaussing.

Send back degaussing credit cards. Call the manual customer service of the issuing bank, follow the instructions to confirm your identity and related information with the bank, send the degaussed card back and wait for the new card to be issued.

it is forbidden to put it with degaussing items. Because the magnetic stripe credit card is afraid of degaussing, it is best to put the credit card in a wallet made of hard leather and manage it separately from other belongings.
