Do Jiangsu Social Security Card and Nanjing Social Security Card need the same bank for merger?

Social security card supports the combination of medical insurance card and social security card, which can not only reduce the number of cards in hand, but also be more convenient to use and carry. If the insured wants to merge two cards, the insured can apply for a new social security card at any branch of the original medical insurance card issuing bank with his ID card, social security card and original medical insurance card. After the medical insurance account is merged into the social security card, the original medical insurance card will be cancelled by the issuing bank.

The social security card used in China belongs to the second generation social security card, but in some places, if only people who pay the medical insurance for urban and rural residents alone, they can still apply for the medical insurance card alone, but that kind of medical insurance card can't be swiped in many pharmacies except going to the hospital for medical treatment. Both provincial social security cards and Nanjing social security cards can be used in Nanjing at the same time. You can also buy medicine or see a doctor at a designated pharmacy or hospital in Nanjing.
