How to resume degaussing a card every day?

Any magnetic card cannot be recovered after degaussing. The strong magnetic field generated by high-frequency electromagnetic waves will magnetize the magnetic card, make the recorded information disordered, and lead to the failure of the magnetic card. After failure, the user can only change the card.

The magnetic card is made of high-strength and high-temperature resistant plastic or paper-wrapped plastic. They are moisture-proof, wear-resistant, flexible, easy to carry and use, and relatively stable and reliable. They are magnetic recording media similar to cards, which use magnetic carriers to record characters and digital information for identification or other purposes.
