Credit cards automatically expire after expiration, and our bank provides card replacement service upon expiration. The new card is valid for five years. One month before the card expires (except for the student version of YOUNG card), a card replacement SMS will be sent to inform the host. Subsequent new cards will be sent to the billing address of the host card holder. By default, registered mail is used (within 15 days), and Platinum/Unlimited Card will express it.
