ID cards will be' degaussed', but' degaussed' is just a common saying, which is not accurate. According to the police officer, because the second-generation ID card is embedded with a chip, not a disk, it cannot be called degaussing.
The chip circuit in the second-generation ID card is as thin as a hair. If the data cannot be read, either the certificate is damaged or there is a gap, which leads to the damage of the chip circuit or improper storage. For example, in the environment of high temperature and strong electromagnetic field, information may also be lost.
A chip in the second-generation ID card failed after being carefully magnetized. If you use the card reader to swipe your ID card too frequently, it will also reduce the life of the ID card chip, and even lead to "degaussing" in serious cases.
Since "degaussing" the ID card will bring us a lot of inconvenience, can the "degaussing" ID card be magnetized?
In this regard, the police in the household affairs hall of the Public Security Bureau introduced that once the chip built in the second-generation ID card is damaged, personal information cannot be read, and this chip can hardly be repaired. "Once it is damaged, you can only re-apply for the second-generation ID card."
How to avoid ID card degaussing? Police officer Zhao reminded that it is best to use an insulating sleeve to protect the second-generation ID card and avoid putting the certificate near places or objects with strong magnetic fields such as mobile phones, induction cookers and televisions. To prevent the chip from failing after being magnetized, don't bend the ID card at will, resulting in line damage and information loss.
