No, the card doesn't have magnetism until it gets to the bank. The ID card can now be read in large public places such as airports. However, if the information inside is lost, it can only be handled by the public security Bureau.
The second generation ID card is loaded with a chip, is an RF IC card, not a magnetic card, under normal circumstances will not be bad, but because the number of ID cards is very large, so it is often said that the ID card has no magnetic, can not be read out. The common circumstances that cause IC card chip damage are generally the following two:
First, IC chip is a circuit, because the external force under the wire may be broken, so bending, beating, heavy pressure are likely to damage the chip inside, many people like to put the ID card in the wallet, in the pants pocket, it is likely to be inadvertently damaged.
Second, although the IC chip is more diamagnetic than the magnetic strip, as long as it is a circuit, it is still afraid of a strong magnetic field. Of course, the small magnets in our daily life, mobile phones, televisions and other magnetic fields are not enough to damage the ID card, which can be assured that this is considered in the design. According to the survey, the most common reason for ID card IC chip damage is the first reason, so please try not to put the ID card in a place that is easy to bend. If the ID card can not be used, please go to the county level public security organ to check to see if it is really damaged, if it is damaged, you need to go to the local police station to change the ID card formalities.
The story is false.
Because the ID card used now is not a magnetic strip card, but a chip card, the chip in the ID card records your relevant information, so it will not be demagnetized. If you can't brush your ID card, it can only be that the chip of the ID card is damaged, and you can only take your ID card to the local police station to apply for a new one. There's no way to do that at the bank.
