If the bank card is frozen due to overdue interest, you can apply to the bank card opening bank for unfreezing after paying it off. The specific procedures are as follows:

1. On bank working days, the cardholder will bring his second-generation ID card and bank card to the bank outlet;

2. Fill in the bank card unfreezing application form;

3. The counter staff should go through the relevant formalities to confirm the reason for freezing;

4. The staff confirms whether the freezing reason has been handled;

5. After confirming that the cardholder has solved the reason for freezing, release the freezing;

6. Thawing is completed.

Note: bank card unfreezing needs to be handled by myself to avoid economic losses and cannot be replaced by others.
