When the bank card is demagnetized or damaged, most banks say that they can't provide magnetic replacement or free card replacement service, so they can only apply for a new card, and in this process, the cost of a new card will be incurred. ICBC, China Construction Bank, Bank of China, Bank of Communications, China CITIC Bank and many other banks all indicated that it would cost some money to reissue bank cards.

China Merchants Bank doesn't need a new card, just take the ID card and degaussed bank card to the counter to replenish magnetism, and there is no need to pay the handling fee. For degaussed bank cards, only replacement cards can be made, but not replacement cards. The magnetic stripe of the bank card is completely sealed, so it is technically impossible to supplement the magnetic field.

Moreover, although some banks can apply for magnetic compensation now, because the bank cards of most banks in China are still magnetic stripe cards, the customer's information is all on the magnetic stripe. Once criminals hold degaussed cards and ask banks to supplement their magnetic fields, it is easy to steal customers' personal information.

Bank card degaussing

The recorded information of bank cards and bankbooks are stored on the magnetic stripe on the back. The strong magnetic field generated by high-frequency electromagnetic waves generated when the mobile phone works will magnetize the credit card, making the recorded information disordered, thus leading to the invalidation of the bank card. At the same time, some people put mobile phones, bank cards and other items together in their bags, which can easily lead to the bank cards being "degaussed".

If the magnetic strips of two bank cards overlap, they are likely to be demagnetized at the same time. It is best to put the bank card in a wallet with hard leather, not too close to the magnetic buckle. Never throw it in a messy bag to prevent sharp objects from being worn, scratched or twisted. At the same time, it is best not to put multiple bank cards together, let alone put two bank cards back to back, so that the magnetic strips collide with each other.

We should try to stay away from the high magnetic field around induction cookers, microwave ovens, televisions, refrigerators and other electrical appliances, and should not place magnetic objects such as mobile phones, computers, palmtop computers, magnets, music stars and business links. If your bank card is damaged, the correct way to deal with it is to cut it open and send it back by registered mail or to your issuing bank, which says "Card is damaged" and you can issue a new card.

People's Network-Degaussed bank cards can only be replaced, and most of them cannot be magnetized.
