Credit cards issued by banks are all valid, usually 3-5 years. On the one hand, from a physical point of view, credit cards are frequently used and will be worn out after long-term use; On the other hand, because the financial situation of credit card holders is constantly changing, banks can decide whether to continue issuing cards according to the cardholder's use after the credit card expires for three years. In addition, the validity period of the credit card can also enable banks to avoid the risks of forgetting to report the loss of the cardholder's credit card, long-term malicious overdraft, and fraudulent use of the credit card after death.
