The health code is updated every day. The golden health code valid for 24 hours is reflected in a golden border around the health code and the injection sign in the upper left corner of the border, indicating that COVID-19 vaccine has been vaccinated.
On this basis, Anhui added a golden icon in the middle, and launched golden health codes in various places to guide more people to vaccinate COVID-19 vaccine.
Therefore, only the health codes of users who have been vaccinated can be displayed in gold.
