Can a bank chip card be kept with a mobile phone?

Chip cards can be placed together with mobile phones,

but magnetic stripe cards cannot be placed together with mobile phones.

Magnetic stripe cards can be easily degaussed. Will putting a bank card (chip card) with a mobile phone affect the use of the bank card?

Don’t worry, it won’t. The bank card has a chip and will not be degaussed by the mobile phone. If the bank card has a magnetic stripe, it is dangerous. Can bank cards with chips and magnetic stripes be kept together with mobile phones

Generally speaking, it is better not to keep them together for a long time, as the magnetism on the bank card will be erased, but once or twice, it is It doesn't matter. Can the bank card be kept with the mobile phone?

It is best to keep them separately. There is a magnet in the phone. If something goes wrong, it would be too troublesome to apply for a new card. Can the phone and bank card be kept together?

Rumor: The electromagnetic waves generated by mobile phones will demagnetize bank cards. Fact: In fact, within the frequency range of mobile phone batteries, the main energy form of electromagnetic waves is electric fields, which will not produce magnetic fields sufficient to change the magnetic stripe information on bank cards. On the website, in addition to the text introduction, the author also provides a complete experimental video: "Some parts of the mobile phone do have magnets. For example, speakers and vibration motors. Then stick the speakers of the mobile phone and the magnetic strip of the bank card closely to At the same time, will it demagnetize the bank card? In fact, putting some common mobile phone receivers close to the bank card is not enough to demagnetize the bank card. As the distance increases, the magnetic induction intensity will decrease with the square of the distance. . To confirm this possibility, the author even disassembled a mobile phone, took out the speaker and vibration motor, and pressed it against the magnetic strip of the bank card, but it was also unable to demagnetize it. Can I keep it with my mobile phone?

Yes! That card is at best a password card. As long as the password on it is used for business, there is no chip in it, and the mobile phone has no radiation on it! Just put it together without worry! Can a chip card be copied? Can a bank chip card be copied?

The chip card uses a personal password, two-way authentication between the card and the reader, and is difficult to copy and forge.

There have been no cases of pure chip IC cards being stolen because they can be copied.

Supplement: Chip cards are divided into pure chip cards and magnetic stripe chip composite cards according to media type. Among them, pure chip cards use chips as the only transaction medium and can only be used at acceptance points with chip reading devices; magnetic stripe chip composite cards can support both chip and magnetic stripe media and can be used at acceptance points that can accept chips. The chip is read, and the magnetic strip is read at other acceptance points, which is the same as the traditional magnetic stripe card. In terms of communication methods, chip cards can be divided into contact cards and contactless cards (as well as contact + contactless dual-interface cards. Can smartphones and bank cards be put together?

Don’t know me Is there a mistake in your understanding? Do you mean that putting a bank card with a mobile phone will cause the bank card to become magnetized and become unusable? The bank cards we currently use are actually magnetic stripe cards, and generally we have a magnetic stripe on the back of the card. Putting bank cards and mobile phones together will not cause card magnetization, but it is still necessary to avoid keeping them together for a long time. For example, I saw an old man putting his bankbook next to the TV for a long time. , but the passbook became magnetized and could not be swiped, so the old man made a trip in vain. What can I do if I put the bank card and the mobile phone together?

The recorded information of the bank card and the passbook are stored on the magnetic strip on the back, and the mobile phone is in vain. The strong magnetic field generated by the high-frequency electromagnetic waves generated during work will magnetize the credit card, causing the recorded information to become invalid. At the same time, some citizens stuff their mobile phones, bank cards and other items together in their bags, which can easily lead to bank card failure. Bank cards are "demagnetized". In addition, if the magnetic strips of two bank cards overlap, they are also likely to be demagnetized at the same time. In addition, the magnetic buckles of women's handbags and some medical examination equipment such as MRI machines are also likely to be demagnetized at the same time. It will cause the bank card to be magnetized.

An expired bank card can be magnetized at the card-issuing bank and can still be used. However, few banks will help you magnetize it and will ask you to pay 10 yuan for a new one. It is a new card, so keep it properly. Will the bank card be demagnetized if placed together with the mobile phone?

Yes, the bank card should not be kept close to the mobile phone or TV for a long time, otherwise it will be demagnetized.
