Because the chip of the bank card will wear out after being used for a long time, the system cannot read the information of the bank card, and it can only be used normally after changing the card. When changing the card, the information of the old card needs to be transferred to the new bank card, and the card changing business can only be handled at the bank's business outlets. The bank staff should verify whether it is my real intention to change the card. I can use my ID card to change my bank card. If your card is a credit card, you just need to call the relevant bank and reissue it. However, you need to pay the production cost. If it is a savings card, you need to carry relevant documents with you. Go to the bank to officially report the loss and reissue a new card. It takes about 7 working days. It also requires production costs. If someone else does it for you. Take both ID cards with you. Taking my ID card to the bank's business hall to report the loss is also a formal loss report. A new card can only be reissued after the official loss is reported. Some banks can get new cards at that time, and some banks have to wait for a week.
