First, the process of canceling the bank card:

1. First of all, if the bank card is a debit card, there is no need to cancel it. When there is no money in the card, the bank card will go to sleep, and the system will automatically cancel the bank card after a while.

2. Explain to the service staff that you want to cancel the account, hand over the bank card to the bank staff, and fill out the account cancellation application form.

3. The cancellation of the bank card is completed.
