Why do magnetic cards degauss? What to do with card demagnetization

Remind everyone that the mobile phone will demagnetize the credit card! In many hotels, the room access control system also uses magnetic cards or keys plated with thin magnetic strips, and I and some of my colleagues have had the cards or magnetic keys fail because of putting the magnetic card together with the mobile phone. Remind all parties not to put their credit cards and mobile phones together when traveling abroad (especially if you use small mobile phones such as T28 or 8210 8850, don't be careless and put your cards and mobile phones in your pockets) to avoid making you lose your money.

When you're abroad, even if you don't spend too much money, it's best to bring an extra card! Attention! Mobile phones will demagnetize credit cards, not only credit cards, but also bus cards & MRT cards!

News**: Dacheng Daily Sports 16th Edition According to reports, banks have recently discovered that there are more and more financial cards or credit cards with magnetic stripes on the back, which are affected by Big Brother electromagnetic waves, so that a card that was originally available for years can be damaged in a day. Shanghai Commercial Bank said that there are many female cardholders who are accustomed to putting the card in the purse with the big brother, if it is not placed properly, the magnetic stripe on the back of the card will come into contact with the big brother, and the electromagnetic wave of the big brother will cause the magnetic stripe on the back of the card to demagnetize.

It is magnetized when it encounters a strong magnetic field.

If the magnetic stripe bank card is demagnetized, you can only take the bank card and ID card to the bank branch to apply for a new one, because the magnetic stripe card is mainly attached to the magnetic stripe, and it cannot be restored just by wiping, and you can only apply for a new one; If the chip card is demagnetized, you can use an eraser to gently wipe the chip, if it is still unusable after wiping, you also need to apply for a new one.

Bank cards should not be put together with mobile phones, induction cookers, microwave ovens and other equipment, as well as magnetic locks, which are the main reasons for credit card demagnetization; Most bank cards are made of PVC plastic, and if they encounter high temperatures, they are likely to deform and cause the magnetic stripe to be unusable.

The bank card cannot be bent, if the bank card is bent or broken, it will definitely not be usable; Try not to stick the two bank cards together, and the magnetic stripe cannot be used if it is damaged; The bank will have an anti-magnetic protective cover, and you can ask for several when applying for a bank card. To apply for a new credit card, you only need to bring your ID card and the bank card that has been demagnetized to the bank outlets, if you can be magnetized, then it will save a lot of procedures, if the bank can not be magnetized can only handle a new one, the bank card can be renewed, you can apply for a new card without repaying the number, but it is more time-consuming.

Sometimes, the bank card loses its magnetism and cannot be used due to some improper placement or some factor. Today I will share with you a little trick to solve this problem easily!

The bus card belongs to the non-contact induction IC card, a little more advanced or even the CPU card, both are made of chips, and the bank card is essentially different, so there is no demagnetization at all, if the bus or subway can not be sensed, that is, the built-in chip is damaged, generally to the designated subway recharge point, call the customer service staff to make up a good one.

For a weakly diamagnetic card, the magnetic field generated by a current of about 10 amperes can demagnetize it;

For magnetic cards with strong diamagnetism, the magnetic field generated by a current of about 100 A can be demagnetized.

However, if the magnetic stripe is damaged, it will make the card unusable:

1.Some backpacks and wallets have "hidden clasps" made of magnets, which should keep the card away from this magnet.

2.Do not place the card near hot or humid environments. Generally, the material of the magnetic stripe card is PVC material, and the high temperature will deform and even burn the PVC, which will directly cause the magnetic stripe to be damaged.

If the magnetic stripe card is left in a humid environment or soaked in water for a long time, it will also cause the card to open the glue, be damaged, and eventually become unusable.

3.Do not bend the card and prevent sharp objects from fraying, scratching, or twisting the magnetic stripe. Several cards rubbed against each other when placed together, and while they could not demagnetize the cards, they would cause damage to the magnetic stripe area. Therefore, it is best to keep the card in a special card case, or in a protective case.

It will only be demagnetized if it is placed with an item with a strong magnetic field for a long time.

Under normal circumstances, the bank card and the smart phone together can not be demagnetized, the reason is that now the wrapping of the smart phone is relatively strong, and most of the built-in speakers, in order to save internal space for the battery and other functions to make concessions, the horn is also very small, in this case the magnetic field is running in a weak electric field, which is not enough to eliminate the magnetic stripe magnetic force of the bank card.

Extended information: Bank card degaussing can be reissued in the following ways:

1.First, prepare your old demagnetized bank card, as well as your ID.

and part of the cash, generally 5 20 yuan, because there will be some handling fees, the specific amount will be depending on the situation;

2.Go to the bank or savings bank where the card is issued;

3.Waiting in line;

4.Tell the teller that your card is demagnetized. He will ask you to give him your bank card and your ID card;

5.If you know your card number, it's easier to do, he will give you a list, you fill it out;

6.Pay a handling fee of 5 yuan;

7.Sign the slip, then he will enter the data into the computer, and then he can use the new card;

8.If you don't know your card number.

And the number on the card is no longer clear, then it is a little troublesome, and you need to handle the loss report and other services. In this way, you need to report the loss first, and then wait a few days to come to the bank to handle the business, and you will have to pay a handling fee of 15 yuan. After the bank card is demagnetized, the bank card that is reported to be lost and reissued is the same as the previous bank card number, but it is just a new card.

Bank card refers to a credit payment instrument with all or part of the functions of consumer credit, transfer and settlement, cash deposit and withdrawal, etc., which is approved by commercial banks (including postal financial institutions) to be issued to the public. Bank cards reduce the circulation of cash and checks, enabling banking.

Breaking through the limitations of time and space, fundamental changes have taken place. The use of the automatic bank card settlement system has made the dream of a "check-free, cashless society" a reality.

Magnetic card is a card-like magnetic recording medium, which uses a magnetic carrier to record character and numerical information for identification or other purposes. Magnetic cards are made of high-strength, high-temperature resistant plastic or paper-coated plastic, which is moisture-resistant, abrasion-resistant, and has a certain degree of flexibility.

It is easy to carry, stable and reliable to use. For example, the bank card we use is one of the most common magnetic stripe cards.

Magnetic cards are easy to use, cheap to cost, and extremely versatile, which can be used to make credit cards, bank cards, subway cards, bus cards, ticket cards, and ** cards; Video game cards, tickets, air tickets, and various transportation toll cards, etc. Today, we use magnetic cards on many occasions, such as dining in canteens, shopping in shopping malls, taking buses, taking **, entering controlled areas, and so on.

From May 1, 2017, banks will completely close the magnetic stripe transactions of chip magnetic stripe composite cards.

The reasons for the demagnetization of bank cards are: 1. The magnetic stripe of bank cards is worn. 2. The magnetic stripe is magnetized by other magnetic fields that interfere with the magnetic stripe, and the recorded information is disordered.

The magnetic stripe of the bank card is made of magnetic particle material, and mobile phones, TVs, computers, motors and other electrical appliances with magnetic fields can cause the demagnetization of the bank card.

When the cardholder inserts the bank card into the card reader, the card reader generates electromotive force, the kinetic energy of the card swiping action becomes electric energy, and the change of current reflects the information recorded on the magnetic stripe, and the system reads the card number, and the machine reads the card number and finds the corresponding balance, transaction information, etc. through the database.

Prevent the magnetic stripe of the bank card from being magnetized, and try to keep the bank card away from mobile phones, TVs, computers, motors and other electrical appliances that have or can generate magnetic fields; Also pay attention to whether there is a strong magnetic buckle on the bag where the bank card is stored, if there is a strong magnetic buckle on the bag where the bank is stored, it will also demagnetize the bank card; Bank cards and bank cards should not be stored next to each other to prevent the magnetic stripe of bank cards from interfering with each other; In addition, when the damage of physical factors such as folding, bumping, scratching, high temperature exposure and other physical factors will also damage and compress the magnetic stripe of the bank card, resulting in the demagnetization of the bank card.

After the card is demagnetized, it can no longer be used. You can only take your ID card and degaussing card, and then go to the business hall to apply for another card.

The card is demagnetized, and you can only reissue a new card from the new, otherwise there is no way to restore the magnetism of the card. You can only re-apply for a new card.

After the card is demagnetized, there is only one way, that is, where is the card done, you go to this place and ask him to re-add the words to you, just like a bank card, it is the same solution.

If the card is demagnetized, it can only be replaced, and the card is demagnetized is equivalent to being broken, and the best way is to re-apply for the card.

Hello, the card degaussing can be handled from scratch. Because the magnetic stripe has been damaged.

Teach you how to degauss your bank card.

Take your ID card and card to the bank where the card is issued to change it, and you will be charged a card fee. It will be done soon, good luck.

Go to your bank and it seems to be free.
