The experience of fighting COVID-19 by QR codes

Our everyday schedule has been altogether subject to the advanced mobile phone applications. Furthermore, this has been the truth for a huge number of individuals in China since halfway through the Coronavirus emergency — and it could yet remain as such for years to come, as the nation fights to recoup from it.

Depending on versatile innovation and large information, the Chinese government has utilised a colour based "health code" system to control individuals' movements and check the spread of the Coronavirus.

The automatically generated quick response codes, regularly known as QR codes, were doled out to residents as a marker of their health or wellbeing status. Despite the fact that specialists presently can't seem to make the wellbeing codes obligatory, in numerous urban areas, residents without the application would not have the option to leave their residential compounds or enter most public places.

The colours were allocated by the provincial epidemic control database: individuals who have been analysed as affirmed, suspected or asymptomatic cases, or individuals with a fever will get the red colour code; their nearby contacts will get the yellow code; and individuals with no record in the database will get the green code — which means they are safe to travel.

The colours of the QR codes choose individuals' opportunity of movement: green code holders are permitted to go inside the area, yellow code holders are not permitted to travel, and red code holders will be treated and isolated.

To get into open places, for example, cafés, markets, business places individuals need to show their own QR code – and just individuals with a green colour code will be permitted to section. Individuals with yellow or red code, it implies you have been hailed for reasons unknown. In the event that, for example, somebody had been on a plane with an individual infected with Coronavirus, that individual would be flagged and code may change the colour. Those with a yellow or red code may be asked to self-isolation – or even need to go into institutional isolation.

The entire thing depends on huge information implies local governments have a database of individuals' movement history, wellbeing history, and whether they have been in close contact with any individual who has contaminated by the coronavirus.

A quarter of a year on, with the infection to a great extent contained and lockdown gauges step by step lifted across the greater part of China, the little square standardised identifications have stayed set up are despite everything administering individuals' lives.

Chinese office labourers show their cell phones with their wellbeing code to a watchman, which shows they have consent to travel and are without infection, as they show up.

Following China's lead, different governments have likewise gone to comparative innovation to fight the infection. Singapore a month ago propelled a contact-tracing cell phone application, which would permit specialists to recognise individuals who have been presented to COVID-19 patients.

The Japanese government is thinking about the reception of a comparable application. Moscow has additionally acquainted a QR code system with track developments and authorise its Coronavirus lockdown.

This kind of simple technology could be introduced in Bangladesh as it does not require any sophisticated technological know-how. The main issues would be for countries like Bangladesh the availability of nation-wide trustworthy database. But there are opportunities on the other hand. Introducing this kind of technology would create a pressure for generating the database.

We need to start somewhere and if we sit idle for things to be prepared completely, it will not happen eventually.
