Must social security cards be linked to payroll cards

Not necessarily linked to the payroll card.

First of all, social security is generally a collective term for five insurance and one gold, of which the social security card contains the functions of the pension, medical, maternity and unemployment insurance cards, and the only thing not covered is the provident fund card. Generally banks expect companies to open accounts there to pay wages on behalf of the company, so different companies will work with different banks, which will also handle different payroll cards. But the provident fund belongs to the management of the Social Security Administration (SSA), and in some places the SSA will designate a bank to handle the provident fund, and if the bank that pays your salary is the bank designated by the SSA to handle the provident fund, then it will be a card for two purposes and the quotas are not in conflict with each other, on the contrary, it will be two separate cards
