Validthru refers to the card validity period of a credit card. The validity of a credit card is expressed in months/years. For example, the validthru05/ 10 on the credit card means that the validity period is May 20 10, which means that the user needs to go to the bank to apply for a new bank card in May 20 10. Once the credit card has passed this validity period, it can no longer be used for consumption, withdrawal and other businesses.

Bank credit cards are generally valid for 3 years, and individual banks are 5 years. After the expiration of the validity period, the bank will decide whether to let customers continue to use credit cards according to their past use of credit cards. Before the expiration of the validity period, the bank will remind users by email, SMS or letter some time in advance.

Credit card, also called debit card, is a credit certificate issued by a commercial bank or credit card company to eligible consumers. It is a card with name, expiration date, number and cardholder's name printed on the front, and a magnetic stripe and signature strip on the back.

After the new card arrives, the cardholder needs to check the relevant information with the bank and open the card (that is, activate the card) before using it. Therefore, even if the card is lost, it is difficult to have the hidden danger of being stolen. As long as the cardholder calls the relevant customer service hotline, he can ask the bank to reissue the card and send it.
