This is a real issue with QR codes. Some apps have implemented better options, including - crucially - the ability to revoke (disable) a code. Snapchat had Snapcodes which had some of these features built in for privacy.
- disillusioned 5y agoNothing about that would solve this, though. The QR code standard is open, and these are just stickers produced that generate a link for any QR code reader. There's nothing to revoke, and no central power that sits in between to perform said revocation.
- RinTohsaka 5y agoRight. You'd have to revoke the URL the QR code points too, not the QR code itself.
