The second-generation ID card belongs to the radio frequency card. Radio frequency cards, like contact IC cards, have no magnetic problems or electrostatic problems, because the coils and chips are encapsulated in the cards. Putting the ID card and the mobile phone together will not cause "degaussing". At present, because the maximum peak power of energy radiation in mobile phones does not exceed 2W, the impact can be ignored.
The ID card is most afraid of physical damage, which may damage the microelectronic equipment inside the ID card and damage the solder joints of the coil and chip. In daily use, don't throw or break your ID card at will, stay away from hot things and don't fold it. Once the identity card is unrecognizable, it can only be reissued by the public security organ.
Extended data:
The second-generation ID card adopts contactless IC technology, which has a built-in chip, not a magnetic stripe, so the ID card itself is not "magnetic". Integrated circuit (IC) is a method of miniaturization in electronics, and is usually fabricated on the surface of a semiconductor wafer. So the chip will fail when it encounters strong magnetic field, strong radiation, extremely high temperature, bending and distortion! But it won't degauss.
Reason for ID card invalidation:
1, the chip is physically damaged by strong external pressure;
2. Strong external radiation or current causes the chip circuit to burn out;
3. A few chips may fail if used for a long time.
People's Network-ID card will not "degauss"! Sticking a band-aid can't protect your ID card.
People's Network-ID card degaussing magnetization? Policeman: There is no such thing as magnetization.
