Covid-19 crisis A better way for contact tracing

China has introduced an app for contract tracing. The public has to use a mobile phone and scan a QR code. The app will show the color code and identify if the person is okay or need to be tested.

It is a good approach.

I have already developed a better approach. Instead of the public using a mobile phone (and some elderly people or children do not carry a mobile phone), they can use a QR code that is pasted to a transit card and use it for contact tracing.

As an alternative, a new transit card can be issued with the QR code already embedded. The public does not need to go through a separate process of pasting the QR code.

The checker will use a mobile phone to read the QR code. It works like the app in China but works in reverse.

I have prepared this video to show how my system works. I hope that the people in charge in Singapore can accept this idea. We can have a solution that is as good, actually better, than China.
