What does social security card 1 mean?

Social security cards can be divided into 1 account and 2 accounts, in which 1 account refers to the social security card account whose personal social security information is verified by the social security department and compared with the identity information of the public security department. 1 user's social security card can be directly used for medical expenses settlement, social security payment record inquiry, social insurance benefits collection, etc. , with higher security and reliability. However, the social security card of category 2 households needs real-name authentication and identity authentication before use, which is not convenient to use compared with the social security card of category 1.
