It’s a bit of a shame that we couldn’t be using something like NFC for checking in to venues, rather than QR codes. The user experience would be much better: just tap your phone. This is quicker and less annoying than opening the check-in app, waiting for the splash screen to go away, tapping “Check In”, positioning the camera, etc.
Sure, establishments will need to buy NFC tags, which are not as cheap as printing a QR code. But I’m betting that the simpler check-in experience would mean more people would be doing so, making it easier for contact tracers to get on top of outbreaks and letting these businesses open up again.
I imagine people want to do the right thing. Make it convenient for them to do so.
