[chbot] CovidCard implementation - how expensive should it be to manufacture 1M of them?

[Trevor Wignall]

I am sure that the CVCard and QR codes do make a difference and allow the
contact tracers to contact some of the potential virus sources or
recipients before they can spread the virus further, and because this
should be a computer-based solution, this frees up those contact tracers to
work on the rest of the potential contacts. I am also sure that if people
don't practice social distancing and don't wear masks and don't scan the QR
codes then even with CVCards the virus could explode exponentially. What I
don't know is how much of a difference the CVCard would make, and one of
the big questions would be to what extent the people who would carry a
CVCard are the same people who would scan QR codes, wear masks, practice
social distances, etc. I fear the overlap could be quite high, so the
CVCard may do little to improve the overall situation as much of the
population largely ignores Covid-19 and does what they want as far as they
think they can get away with it.
I also fear people who do start carrying CVCards might stop scanning QR
codes thinking that they no longer need to do so, but fortunately there is
a solution - set up a different type of CVCard to place by the QR codes so
the CVCards (both those carried and those at the business entrances) record
those people's movements.
Cheers
