What is the role of electronic health records in automobile maintenance?

The function of electronic automobile archives is to enable car owners to query their own automobile maintenance archives, which provides a basis for after-sales protection. For enterprises, there will be a regulatory function, because car owners can score enterprises from the owner's APP, and the rating will be monitored by government departments. Now car owners have different platforms in different regions, and many places in Guangdong and Shandong are "stocked cars", but it is said that the national maintenance records can be checked after 20 19.
