After the CMB credit card is degaussed or damaged, you can dial the CMB credit card number: 800820555, enter the ID number and inquiry password-and then select "9" to enter the manual service to apply for card replacement. Transfer to manual service, explain the situation to the customer service specialist and ask the credit card center to reissue a new card. After the new card is reissued, the credit card center will mail it out. After receiving the new card, re-open the card and activate it, and it can be used normally.

Precautionary measures to avoid degaussing credit cards;

Don't put a magnetic card or something magnetic on it. Some medical examination equipment, such as the magnetic hidden buckle of a lady's handbag and the nuclear magnetic resonance instrument, can also cause the bank card to be magnetized.

Don't put it with metal, such as keys (especially security door keys).

Don't put it with electronic products with strong magnetic field effect such as mobile phones, computers, televisions, microwave ovens, radios and refrigerators.

Buy a special booth and add a booth.

Avoid physical damage to the magnetic stripe. Due to careless storage or use, the magnetic stripe card is subjected to external force, and the magnetic stripe information on the card is lost.

Avoid overlapping magnetic strips of two bank cards, and inadvertently put two magnetic cards together back to back, so that their magnetic media collide with each other and are damaged.

Stay away from places near high temperatures.
