I already have a medical insurance card. Do I still need a social security card?

You already have a social security card, so you don't need to apply for a medical insurance card, because the social security card already contains a medical insurance card. Even if you have two cards at the same time, you can't reimburse them at the same time. If you want to improve your security, you can consider investing in a guaranteed commercial insurance.

Social security card is different from medical insurance card.

The medical insurance card has a single function, that is, it is used when seeing a doctor and buying medicine. In some areas, medical insurance cards were issued before social insurance cards were issued, and the function of the original medical insurance card was invalid after the social insurance cards were issued again, which was over-issued.
