2. Scratch the magnetic stripe of the card with a magnet or a sharp object to destroy the information storage record of the card;
3. It is also very easy to degauss the card by holding it with a relatively magnetic object or by pressing and twisting it by gravity.
The above is the way to degauss the card quickly.
How to keep the bank card
1. Bank cards cannot be stored with bank cards or other important documents. The mutual friction between bank cards can easily lead to degaussing, which is not conducive to the safety of funds when lost, giving criminals an opportunity;
2. Don't put the bank card with objects with strong magnetic fields such as smart appliances, which will easily demagnetize the bank card, and don't get close to sharp objects. Sharp objects will scratch the magnetic stripe of the bank card, resulting in the loss of information and failure to use it normally;
3. Don't put the bank card at will, put it in an independent space, and don't let heavy objects press on the bank card, which is also very unfavorable for the storage of the bank card.
