What is the situation that foreign social security card can not be deducted in Shanghai dispensing medicine

Can only be used locally. According to China's social security system, each region's social security card can only be used in the local area, can not be used across the region. Therefore, if you have a social security card from abroad, the pharmacy will not be able to deduct the fee through the social security card when you dispense medicine in Shanghai. This is because social security cards are issued based on the regional social security system, and social security cards from different regions cannot be recognized and used by each other.
