There are two accounts on the social security card. One is the medical insurance account, which is used to store the medical insurance expenses paid by the unit, and this money can be used to reimburse the legitimate expenses incurred by the insured during the medical treatment. The other is a financial account, which requires the insured to go through the activation procedures himself, and can use the funds stored in it like a bank card. Wages will not be directly stored in the social security card, but will be credited to the bank account designated by employees through other channels (such as bank transfer) when paying wages. Social medical insurance is paid by the employer to the social pooling fund corresponding to the employees or the special fund set up by the subordinate institutions of institutions on a monthly basis.
