QR codes are used for everything from opening a restaurant menu to making payments: just point your camera at the QR code, and your phone will automatically open the relevant page. But what happens when you get a QR code in a message? Or what if it’s a screenshot instead?
A man in the Australian state of South Australia was arrested Wednesday after allegedly placing his own QR codes on two official covid-19 check-in signs, according to police in South Australia. The man was granted bail with one very specific condition: He can’t carry “loose QR codes” anywhere.
