The version of the health code will be modified, for example, the important fonts will become larger and easier to check. If you see that there is no Phnom Penh, the version will be upgraded.
There are three kinds of health codes: green code can enter the city directly, red code can be isolated 14 days, and yellow code can be isolated within 7 days. The application scope of health code covers community management, resumption of business, transportation, starting school, drug purchase registration, supermarkets and shopping malls, which can help communities, enterprises and schools to do key work such as epidemic prevention management and epidemic control.
