Under normal circumstances, all kinds of new cards now have strong performance of preventing magnetic cards from degaussing. As long as we don't destroy them artificially, it will be difficult to be degaussed. Unless the old card has not been replaced, it may be degaussed, so we can keep it normally. So many old cards may indeed have disappeared in some ways, so pay attention to these old cards.

1, away from the magnet

First of all, the main culprit of degaussing these cards is magnets, so we should stay away from things with magnets or magnetic fields, especially some factories will have some strong magnetic products, which may erase the magnetism on any card, so when we touch these things, we must pay attention to keeping all magnetic cards away from us, or simply don't put the cards on us.

2. Stay away from items with strong electric radiation.

In addition to magnets or magnetic fields, if you have something with strong electric radiation, it is also possible to demagnetize the magnetic card, so we should try to stay away from the state with strong electric radiation in our daily life or work, so if we enter this state, or have to touch it for some reason, we must also put the card on us before touching these things.

3. Wear antimagnetic protective gear.

If the nature of our work is that we have to touch something, such as a magnetic field or a magnet, then we can wear some specially designed appliances to prevent the magnetic field from affecting us. Because these appliances are very professional, it is difficult for ordinary people to get them, so we may have to apply through some special channels, or when we work in some factories, the equipment in the factories will specially equip us with some of these things, and we just need to put the cards in these protective supplies.
