The original intention of promoting resident health card in China is to solve the problem of cross-institutional and cross-regional medical insurance settlement for urban and rural residents. People often complain that they spend a lot of time waiting in line when registering, and they have to apply for an independent "medical card" containing medical records every time they go to the hospital. Because there is no * * * information between different regions and hospitals, patients often need to carry out repeated examinations and establish repeated health records.
