Credit cards can be used normally after they have been sealed and returned. If the cardholder's credit card is blocked due to overdue repayment, then after the cardholder has paid off all the overdue amount, the cardholder only needs to call the customer service phone of the credit card issuing bank and apply to the customer service for unblocking the credit card, and then the credit card can be unblocked according to the voice prompt of the customer service, and then it can be used normally.

a Credit Card, also known as a credit card/overdraft card, is issued by a bank and gives cardholders a certain credit limit, within which they can spend first and then repay. Credit cards can provide settlement services, facilitate shopping and consumption, reduce the use of cash and currency, enhance the sense of security, and help cardholders manage their own funds reasonably. If there are extra funds deposited in the credit card, the current interest is not counted. It is recommended that the cardholder directly spend the limit and then repay.

if the cardholder's credit card is about to expire, the bank will send a new card to the billing address before the cardholder's card expires. after receiving the new card, the cardholder can use the new card by activating it, and the old card will be invalid, and the old card needs to be cut and destroyed by the cardholder himself.

the old card can be used until the expiration date if the new card has not been received or has not been opened.

if the cardholder fails to receive the new card as scheduled when the card expires, the cardholder needs to call the credit card service hotline of the credit card issuing bank for enquiry.

Tips: If the cardholder's billing address is changed, the cardholder needs to change his billing address through the "Credit Card-Credit Card Management-Personal Information" menu of mobile banking at least 3 months before the card expires.
