How to protect ID card chip

The second-generation ID cards currently used by residents have a built-in chip, which stores resident identity information. This chip cannot be copied and is highly anti-counterfeiting. The chip has a large storage capacity and the written information can be divided safely. Hierarchical, partitioned storage. There are ID card reading devices in Internet cafes, hotels, banks, airports, etc., which can identify the authenticity of the ID card by reading the information in the card. Once the built-in chip is damaged or becomes invalid after being magnetized, personal information cannot be read, and the chip is basically irreparable and requires a new second-generation ID card.

Many citizens usually pay more attention to preventing the damage of ID cards, but rarely pay attention to the possibility that the built-in chip may be damaged by magnetization. Prolonged contact with items with magnetic strips such as mobile phones, bank cards, stereos, microwave ovens, and card readers on buses will be detrimental to the built-in chip of the second-generation ID card, because the strong magnetic field generated by the high-frequency electromagnetic waves emitted by these items will affect the chip. How to prevent damage to the second-generation card is explained on the card holder. ID cards should avoid strong magnetic fields, strong radiation and extremely high temperatures, and should avoid bending and twisting.
