Will the mobile phone and ID card be demagnetized together?

Mobile phones and ID cards will not be demagnetized together. The reasons are: 1. The ID card has coils and chips integrated inside it. Unlike traditional tapes, hard drives and other storage media, there are no magnetized substances; 2. The electromagnetic radiation of mobile phones is high-frequency electromagnetic waves, with frequencies as high as hundreds of thousands to tens of millions of Hz, and has no ability to magnetize ID cards. The magnets in the mobile phone speakers will not have a demagnetizing effect on the ID card. We can safely put the ID card and mobile phone together, and pay attention to avoid damage to the ID card and protect its normal use so that it can serve us better.

In modern society, ID card is the most commonly used document and can be seen everywhere in our daily life. Mobile phones have also become an indispensable communication tool for us, and almost everyone has one. Whether the two will affect each other has always been one of the issues of concern to the general public. However, in actual use, we can safely use mobile phones and ID cards in the same environment at the same time, because they will not be degaussed.

#1. There are coils and chips integrated into the ID card. Unlike traditional tapes, hard drives and other storage media, there are no magnetized substances. Its working principle is similar to wireless charging technology. When data needs to be read, the coil inside the ID card induces a current under the action of an external electric field, thereby powering the chip and enabling data communication. Except for the process of writing ID card information, the working principle of the coil and chip of the ID card is not affected by the external magnetic field.

2. Although mobile phones have the characteristics of electromagnetic radiation and magnetic speakers, they will not produce strong magnetic fields on ID cards. The electromagnetic radiation of mobile phones is high-frequency electromagnetic waves, with frequencies as high as hundreds of thousands to tens of millions of Hz, and has no ability to magnetize ID cards. The magnets in the mobile phone speakers will not have a demagnetizing effect on the ID card. Therefore, in daily use, consumers can safely carry their mobile phones and ID cards together.

It is worth noting that although ID cards will not be affected by degaussing by mobile phones, they still have the possibility of other damage. For example, if the ID card is folded and bent or exceeds the specified temperature range, the internal coil or chip may be damaged, thus affecting the normal use of the ID card. In addition, when using the ID card, be careful not to force it in or out to avoid poor contact and damage.

In short, the ID card and the mobile phone will not degauss each other. In daily use, we can safely put the ID card and mobile phone together, and pay attention to avoid damage to the ID card and protect its normal use so that it can better serve us.
