If you try at another ATM, you need to bring your ID card and bank card to the counter of the bank branch to change your card.

The central bank issued the Notice of the People's Bank of China on Further Strengthening the Risk Management of Bank Cards, proposing that "the magnetic stripe transaction of chip magnetic stripe composite cards will be completely closed from May 20 1 July1day" and requiring commercial banks to speed up the progress of replacing existing magnetic stripe cards with financial ic cards. This also means that from May next year 1, bank magnetic stripe cards cannot be swiped, and new chip cards must be replaced at the counter.

Extended data:

main reason

The recorded information of bank cards and bankbooks are stored on the magnetic stripe on the back. The strong magnetic field generated by high-frequency electromagnetic waves generated when the mobile phone works will magnetize the credit card, making the recorded information disordered, thus leading to the invalidation of the bank card. At the same time, some residents put mobile phones, bank cards and other items together in their bags, which can easily lead to the bank cards being "degaussed".

In addition, if the magnetic strips of two bank cards overlap, they are likely to be demagnetized at the same time. In addition, some medical inspection equipment such as the magnetic hidden buckle of the lady's handbag and the nuclear magnetic resonance instrument will also cause the bank card to be magnetized.

It is best to pay attention to the following points: the bank card is best placed in a hard wallet, not too close to the magnetic buckle; Bank cards should be as far away from the high magnetic fields around induction cookers, microwave ovens, televisions, refrigerators and other electrical appliances as possible, and should not be placed with magnetic objects such as mobile phones, computers, palmtop computers, magnets, music stars and business communications.

Don't throw your bank card in a messy bag at will to prevent sharp objects from being worn, scratched, twisted or broken; Don't store multiple bank cards together, and don't put them back to back, so as to avoid the magnetic strips rubbing against each other; For bank cards that have not been used for a long time, it is best to go to the bank for trial in advance and solve the problems immediately when found.

Degaussing: When the magnetized material is affected by external energy, such as heating and impact, what is the magnetic domain? The direction of magnetic distance will become inconsistent, and the magnetism will weaken or disappear. This process is called degaussing. Another common method is to place the magnetic material in an alternating magnetic field and gradually weaken the intensity of the alternating magnetic field until it disappears and the material demagnetizes. Such as CRT kinescope.

Degaussing is a common technique to destroy data stored on magnetic tape. Using degaussing equipment like a box to change the magnetic field of the tape can effectively destroy the data on the tape.

In this way, the tape (without pre-written tracks) can be reused. Degaussing can also be used to erase the contents of hard disks and floppy disks. But degaussing cannot erase the contents of USB thumb drives, smart phones or various flash memory devices.

Degaussing is usually used to improve the resolution of images on electronic display screens. Many display manufacturers install internal degaussing coils on the display to degauss the display after it is turned on. Both display and cathode ray tube (CRT) technology require the construction of magnetic field.
