Maybe a dumb question, but how is this suppose to work for iphone users? They wont have google play, and it seems like android/google play is required here? There is no way they would cut out such a huge chunk of the market.
iPhones have attestation too: https://developer.apple.com/documentation/devicecheck/establ... It'll just be more clunky because you have to install their app.
I don't know what technology they're using, but when I scanned the QR code it launched (downloaded?) an iOS app of sorts with one tap, similar to the way Google tried Instant Apps a few years back. Didn't even need to double tap the power button like usual.
