How to replace the old medical insurance card in Guangzhou with a new one?

Hello, dear 1. The easiest way is to bring my original ID card and my old medical insurance card to the counter of the social security center in the province and city where I am located to change the card manually. 2. Or we can apply online. You can apply in the official WeChat account and pay attention to the social security number of our city. After the approval, we can pick up the card at the designated card outlets. 3. We can also use the self-service business card printing machine to change cards, but the self-service business card printing machine needs the following materials: my second-generation ID card, my social security card transaction password, my debit card with UnionPay logo, and then follow the instructions of the machine.
