What is the social security cost? How to get it? I only have a social security card in my hand. Please explain in detail. The more detailed, the better.

The social security card is a substitute for the original social security book. After the original social security fund incurred medical expenses, it must be paid by itself first, and then reimbursed by the medical insurance center through the unit. Social security cards are much more convenient. As long as you exceed the deductible, you only need to bear one copy yourself, so you don't have to submit an expense account. You take real-time settlement. The money that the unit originally needed to seek reimbursement from the medical insurance center is now settled directly with the medical insurance center.
