The grid-based management under the epidemic has made the community preventable and controllable, but it has also turned the community into a relatively closed “island” between the community and the area, and the community residents become depressed because they cannot freely enter and exit the activities. It is true that digital life can enable people to realize the free flow of information, and e-commerce platforms can also realize the logistics connection, but people are animals with social attributes, people need to work, learn and socialize, and individuals need to move. The longer we fight the epidemic, the more realistic and necessary is the need for mobility.

One of the most important prerequisites for the realization of population health mobility is the establishment of a mechanism for identifying the health status of the population and facilitating the mutual recognition and sharing of health status information among communities, institutions, units, companies and regions.

Realistic needs are the direct motivation for innovation, and a health mobility management model for the population under the epidemic was born: in response to the urgent situation of returning to work, school and work, especially in response to the resumption of work by many Macao enterprises, the demand for foreign workers (hereinafter referred to as “migrant laborers”) is gradually rising, and in order to win the battle of preventing epidemics and the battle of economic recovery at the same time, Vanguard Information Technology Ltd. utilized the “Macao Health Code” to combine with the “Macao Health Code”, which is the most popular health identification system in Macao. Macao Health Code” combined with the blockchain solution to lay a solid foundation for the prevention and control of epidemics in the mobility of Macao residents and the mobility of people across the region (Guangdong and Macao).

The “Macao Health Code” model was launched to implement the three-color dynamic management of “Green Code, Red Code and Yellow Code” for Macao residents and people entering Macao, whereby those who receive the Green Code will pass through with the Code, while those who receive the Red Code and Yellow Code will be required to follow the stipulated requirements of segregation and health punch card, and will only be able to switch to the Green Code and pass through with the Green Code when they have met the requirements.
