The fifth and final proposal is to use the COVID-19 app to generate a QR code that displays information at every user interaction with the coronavirus response. The problem we're trying to solve here is the time-consuming task of identifying people at each interaction with the coronavirus response. The COVID-19 app is a scanner of QR codes, but imagine if it was also a displayer of QR codes—that is, the app could also present information. As it is currently, the app's a data pool. It pulls in location information of what is being scanned, but imagine if it could also push data.
