There are two ways to judge whether the bank card is degaussed: one is to insert the bank card into the ATM to see if the password can be entered; The second is to go to the bank counter and let the salesperson brush it on the counter for testing.

There are four reasons for degaussing bank cards. Let me introduce it.

1, bank card and mobile phone together.

Bank cards are put together by magnets.

3. The bank card and the second-generation ID card are put together.

4. Put multiple bank cards together. It is best to put it in the nail groove and store it independently.

So how should we guard against it?

Tip 1: Because the magnetic stripe of bank card is easy to be magnetized, don't put magnetized items such as mobile phone and PDA with the credit card when going out to avoid magnetization; It is best not to put bank cards next to each other to prevent magnetic strips from interfering with each other.

Tip 2: Some bank cards have not been used for a long time, and they are only remembered when they are away from home. They need to pay by credit card, not by credit card. This is mainly because the bank card has not been used for a long time, the card has been damaged unintentionally, or the magnetic stripe information has been demagnetized, so it is best to use it in advance before going out, and solve the problems as soon as possible.

Tip 3: No matter whether you use the card in this city or in another place, you should keep the transaction slip properly. On the one hand, if there are repeated deductions due to cross-bank or cross-regional bank card transactions, you should contact the issuing bank with the transaction slip in time; On the other hand, if you discard the receipt at will when withdrawing money from ATM, it will also give criminals with bank cards an opportunity.
