The information on the front of a credit card includes card number, expiration date, card grade and type, and pinyin name. The amount of information is still relatively large, and the card number and expiration date are both key information. If it is leaked, there is still a certain risk. It is recommended to change the card as soon as possible. In this case, there is no need to cancel the card again, just call the customer service hotline to change the card at risk. For example, my CCB credit card. If the information is leaked or risky, I can call the customer service hotline to apply for a new card. After changing the card, the card number, expiration date and CVV code will all change, so that the account will be safe. The points and accounts are still there and will be automatically transferred to the new card. In this case, CCB is exempt from handling fees and production costs.
