The high-speed development of the Internet has opened a new door for people to obtain knowledge. However, the knowledge of the fish dragon on the network is mixed, and people will be confused by rumors. If you first "hot" mobile phone base station radiant rumors, leading to a group of households to "rights protection", strongly requested to remove the base station.
Another example is the discovery of the leading force waves, and there is a message to represent that the extraction wave is discovered late, so it is more powerful than electromagnetic waves. At the same time, X Bao is also rapidly followed, and there is no one day, anti-gravitational waves are made.
These rumors we seem to feel more commendable. But most of the elders in the family have contacted this area, so they will be convinced of these news. For us, how to recognize rumors, crack rumors, become a top priority.
Recently, Apple Pay landed in China and successfully set off a boom of mobile phone electronic consumption. At the same time, some people said that the mobile phone binding bank card is very good. After successfully kitting, you don't have to go out with a bank card.
However, considering that the people who don't understand their mobile phone payments, don't say what Apple Pay, cash and bank cards are the "wallet" they bring on the street, then the problem is coming, the mobile phone will make bank cards to deactivate? Let's take a look.
Bank card relies on magnetic small particle storage personal information
To explain this problem, it is necessary to introduce the magnetic card and the working principle of the magnetic card. In general, the magnetic card is a card, and the "magnet" is used to store the card. From the substrate (plastic plate), the magnetic card can be divided into PET card, PVC card and three paper cards. If the magnetic card is classified according to the magnetic structure, it is divided into two types of magnetic stripe cards and full magnetic cards.
The vast majority of bank cards are magnetic cards, and many ferromagnetic substance small particles are evenly distributed on the back of the magnetic strip. These small particles can be imagined into a small compass. When the direction of these small compass is messy, the magnetic strip does not show magnetic resistance. However, when all the direction of the small compass is all consistent, it will show magnetic.
If the surface of the magnetic strip is divided into many small grids, the magnetic properties of each grid separately, and the magnetic strip has information. At the time of the bank card, the magnetic head of the writing card will make a changed magnetic field, change the respective small magnetic fields on the magnetic strip, thus writing information such as card numbers on the magnetic strip. Banks link you the account created in the bank computer system with the card number stored on the bank card. This way you can use this bank card to access your account.
High temperature, strong magnetic field influence, external force hit will cause "degaussing"
The so-called degaux refers to the magnetic particles on the magnetic card lose the magnetic properties of the present invention. In general, the degauss is three kinds of incentives. First, the external force hits, the second is high temperature, and the third is a strong magnetic field. And the elders should not put the bank card near the phone, referring to the interference of the strong magnetic field.
No radiation in the form of a strong magnetic field during work
We all know that the phone is mainly relying primarily on electromagnetic waves when the mobile phone is working. However, in the frequency area of the mobile phone, its main energy form is an electric field rather than a magnetic field, which results in insufficient magnetic field strength to make bank cards. More importantly, the current magnetic card has certain anti-magnetic capabilities. So there is no need to be too worried that the bank card is dedupted by phone.
There are also netizens to show doubts, although the magnetic field energy generated by the mobile phone work is small, do other parts of the mobile phone do not generate a magnetic field when working? In fact, there are indeed other parts in your mobile phone to generate magnetic fields, such as vibration motors, speakers, and more. However, the strength of the magnetic field generated by these parts is also very low, do not worry about the problem of disability problems caused by the bank card close to the phone.
Chipping card is gradually replacing magnetic card
In these years, the magnetic strip bank card is gradually being replaced by the chip bank card. In our lives, both bus cards, meals or ID cards, most of these cards are chip cards. All of its information is stored in a particular chip, relying on RF technology to identify, do not have to worry about the problem of desence.
It can be seen that the so-called mobile phone will make bank card disability phenomena need not worry. But in life, Xiaobian still recommends that you keep your bank card away from your phone. After all, we don't guarantee that all mobile phone quality is excellent, and electromagnetic radiation can guarantee in a reasonable level. Moreover, the quality of bank cards in all localities may vary. If you put your phone and bank cards together, you can make your bank card mechanically damage.
Life is always full of various rumors, and can correctly identify rumors, and disseminate scientific knowledge to others is the obligation to everyone. Now that you have known your phone and you will not make bank cards. If you want to talk about this problem next time, you will give a scientific answer.
