Will keeping a membership card in a phone case cause it to demagnetize?

    Membership cardActually, it's also a type of magnetic card. Next, let's look at under what circumstances a membership card will experience demagnetization.

    Magnetic cards are currently the most mainstream information storage medium, with bank cards being the most common. Generally, magnetic stripe cards in urban areas do not experience demagnetization. Below is an explanation of under what circumstances magnetic cards may experience demagnetization.

1. GeneralMagnetic stripe cardsplacing them near magnets or household appliances with strong magnetic field effects, causing the magnetic medium inside the card to fail due to the magnetic field. If the magnetic stripe is placed too close to the magnetic clasp inside the wallet or wallet, the magnetic medium on the card will be demagnetized and damaged. Due to improper storage or use, magnetic stripe cards may be subjected to external force, causing the magnetic stripe information on the card to be lost. Such as compression, breaking, scratching, or dirtying. Unintentionally placing two magnetic cards back-to-back, their magnetic media rub against and collide, resulting in damage.

2. Another reason for magnetic reading failure is poor maintenance of the terminal magnetic reading head. This problem is relatively easy to solve; the card issuer only needs to use a simple terminal cleaning device. This cleaning device comes with a card cleaner that periodically circles the terminal to remove lint and dust from the surface. Proper maintenance of terminal magnetic heads can improve the terminal's card reading capability and reduce the error rate by 30%.

3. Improper operation by the cashier at the designated merchant, as well as malfunctions in the POS magnetic reader head, can also cause magnetic reading failures. The causes of magnetic writing errors include improper debugging of the magnetic writing equipment, incomplete erasure of the original magnetic stripe information during rewriting, improper handling of magnetic cards during transportation and storage, and the resulting errors. It is worth noting that some early factory or individual manufacturers' devices, without adjustment, may also cause varying degrees of magnetic writing errors when using cards of different thicknesses.
