China, with the help of the country's big technology companies, is identifying those infected with coronaviruses using QR codes

Monitoring millions of people to identify possible infected with the Wuhan coronavirus is not easy. The system that China has devised for this involves using the country's large digital platforms and assigning color codes to each inhabitant according to their state, as reported by Reuters. One more attempt to stop the spread of the virus.

The efforts by the Chinese authorities to curb the spread of the Covid-19 coronavirus in the country are especially significant. Two of Asia's biggest tech giants (Alibaba and Tencent) have teamed up with the Chinese government to more easily identify the population and its likely infected, according to the report.

Alibaba recently launched a kind of survey to each user who, after completing it, indicating their symptoms and narrowing the data with the trips and places each inhabitant has been, assigns a QR code.This code can be of three different colors depending on the severity: green means that the user can travel freely, yellow forces him to be quarantined for 7 days and red if the quarantine must be 14 days.

Last week the feature was deployed in the Hangzhou area to test its effectiveness, and since this past Sunday, Alipay has begun working with federal authorities to begin implementing it across the country. Reuters explains that the objective of the authorities is to use it at travel checkpoints to verify who can and who cannot travel in order to mitigate the risks of Covid-19 infection.

Tencent has created a very similar feature that works using the WeChat messaging app. In the first place, it has been tested in Shenzhen and little by little it will expand throughout the Guangdong province.

State and technology to stop Covid-19

These color QR codes are yet another example of how China is coping with the crisis caused by the coronavirus originating in Wuhan. Just yesterday it came to light how the government, with the help of the country's big technology companies, has implemented online classes so that students do not have to attend school and avoid possible infections. There are also for example robots patrolling public places to help the population:

They comment on Telegraph that the country has also taken advantage of its huge deployment of surveillance cameras with artificial intelligence to track possible infected. And apparently the masks do not prevent the cameras from identifying the inhabitants.
