How QR codes are helping in fighting COVID-19

1. Collect information about people

Chinese authorities in the city of Shanghai have found a unique way to use the QR codes for tracking the information of people. One of the biggest challenges associated with coronavirus is the difficulty in identifying those who have been affected by the virus. Affected people start showing the symptom only after a few days, and by then he/she would have spread it to multiple people unknowingly.

By sticking QR codes across every coach in the metro trains, every passenger is advised to scan the QR code with their smartphone and provide their basic information. The authorities then create a repository of this information after they scan the QR codes. In case any passenger in that coach is affected with coronavirus, the other passengers can be easily notified with this bgd foundation. 

2. Identify affected people

China has found another innovative way to fight the coronavirus. The authorities have taken the help of tech giant Alibaba to develop an application that helps in identifying people who are affected or prone to catching the coronavirus. The residents of Hangzhou have been asked to fill out a form with their ID number, their travel history, and any possible symptoms. This information is converted into a color (red, yellow and green) based QR code on their mobiles that indicate their health status. People with red code have to quarantine themselves for 14 days, those with yellow for seven days and those with green are allowed to travel freely. The authorities scan the QR codes at various checkpoints such as railway stations, bus stations, or even when a person enters a residential apartment to prevent these people from entering and spreading the virus to a large bd donation.

3. Facilitate cashless transaction

The deep fear of the authorities and the general population of the coronavirus is mainly due to the ability of the virus to spread effortlessly to other people. When an unaffected person touches an object that was previously touched by an affected person, the chances of the virus entering his body is very donation bd. 

Money, one of the most transferred objects in the world, can also be a potential carrier of the virus. Fortunately, the advent of many payment apps like Google Pay has utilized QR codes to facilitate cashless transactions , thereby eliminating the need to touch and transfer cash. All you have to do is scan the QR code in a shop or the QR code on a person’s mobile to transfer the required amount.
