Deregulation of credit card (debit card) does not mean cancellation of the card, but refers to that after the credit card (debit card) is controlled, the cardholder provides consumption vouchers with suspicious transactions, such as receipts, POS bills, invoices, etc. Prove to the bank that this is real consumption. After investigation and verification, the bank will lift the control of credit cards (debit cards) and resume the use of credit cards (debit cards).
It should be noted that not all controlled credit cards (debit cards) can be released smoothly, so try to use credit cards (debit cards) for daily consumption to avoid being controlled by banks.
