When a cardholder gets a new card, he usually scrapes and destroys the old card. Because the old card has no function and contains the cardholder's personal privacy, destroying the old card can ensure the safety of the customer's personal information. It is suggested that cardholders get a new card, complete the card opening procedures as soon as possible, and then cut and destroy the old card to ensure that the information will not be leaked.

Credit card is a credit certificate issued by commercial banks or credit card companies to qualified consumers.
