What is the difference between the social security card and which bank's?

The social security cards, issuing banks and functions of the four major banks are different.

The social security cards of the four major banks are issued by their respective commercial banks. For example, China Industrial and Commercial Bank issued the social security card of ICBC, China Agricultural Bank issued the social security card of Agricultural Bank, China Bank issued the social security card of bank, and China Construction Bank issued the social security card of China Construction Bank. In addition, although the social security cards of these four banks are all used to manage and use social security-related benefits and services, their specific functions may be somewhat different. Social security cards can be used for medical insurance reimbursement, personal social security account management, social security payment, pension collection and other different purposes.
