Why do the social security cards of elderly retirees have to be changed every year?

1. The social security card contains sensitive information such as personal identity information and social security payment records. If a card is used for too long, there will be security risks or information leakage. Therefore, changing the card once a year can ensure the security of the social security card and personal privacy information.

2. Modern social security card systems and equipment emerge one after another, and the technology is constantly upgrading. The new generation social security card is more intelligent, safe and convenient, with more functions and advantages. Therefore, the social security card must be upgraded and replaced in time to adapt to the changes in new technologies and new demands. Changing the social security card once a year also helps to maintain the update speed and service efficiency of the social security system.
