Under what circumstances does a magnetic stripe membership card lose its magnetization?

Currently, there are many types of membership cards, including barcode membership cards, magnetic stripe membership cards, IC membership cards, etc. Among them, magnetic stripe membership cards are still quite popular. Therefore, it is inexpensive and widely used, making it very popular among merchants. However, magnetic stripe membership cards have a drawback: they are easily demagnetized. Below, Jianhe Chengda will explain under what circumstances magnetic stripe membership cards can be demagnetized.
 
1. Place the magnetic stripe card near a magnet or household appliances with strong magnetic field effects, causing the magnetic medium inside the card to fail due to the magnetic field.

2. If the magnetic stripe is placed too close to the magnetic clasp inside the wallet or wallet, the magnetic medium on the card is 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.

3. Improper operation by the cashier at the contracted merchant, as well as malfunctions in the POS magnetic reader, 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.

4. Another reason for magnetic reading failure is poor maintenance of the terminal magnetic reading head. This problem is relatively easy to solve; the issuing bank only needs to use a simple terminal cleaning instrument. 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%.

Magnetic stripe membership cards are very prone to demagnetization, so in such cases, we usually tell customers to keep their magnetic stripe membership cards properly when issuing them to avoid unnecessary trouble during future use.
