The general service life of China Construction Bank is 3-5 years. For security reasons, bank cards are time-limited. First of all, bank cards will wear out during use, and people and things will have a long life. After a certain period of time or program wear, there will be more or less damage. So after a period of time, it is necessary to update the card, so as to ensure the normal use of the card.

The bank card function needs to be updated. In order to give customers a better experience and service, the functions of bank cards need to be constantly updated, so as to greatly improve the security performance of bank cards and greatly reduce the possibility and risk of bank cards being stolen and swiped on a certain basis. If the bank card is idle or lost for a long time, the longer the term, the greater the possibility and harm, and the higher the risk.

At the same time, it also sets a time limit for bank cards, adding another layer of protection. Because when paying online, sometimes the system will need the number of customers to enter sensitive information such as time limit and the last three codes. If you add one step of personal verification, you can also have one more personal information and property protection. Bank card cancellation. For most people, it is safe to cancel the bank card, but this is not the case. After the bank card is cancelled again, there are great security risks. It takes 45 days to cancel the bank card. In these 45 days, the cardholder needs to settle all debts without breach of contract, and cannot use the card for consumption within these 45 days. The bank card can only be officially cancelled if an accident is recorded after 45 days.

Bank card cancellation will also have unsafe factors. Some banks stipulate that the cancelled bank card can re-apply for activation within 45 days after cancellation. Remember, during this period, the bank card cannot be damaged or lost. Generally, if it is lost in the cancellation process, it may be stolen, and online transactions or even transfers can still be made.
