Re:How a QR code works by rainbowzootsuit on Wednesday September 14, 2022 @11:10PM (#32846518)
My child's daycare uses a cell phone app for checking in and out the children. It requires one to scan a QR code, then enter a PIN, and scribble a signature.

I am not able to get over this seeming like security theater, not to mention being somewhat indignant to the presumptive ownership of a smart phone to go through this song and dance when a piece of paper would suffice as a record.

I've captured the qr code and found that it's not geo-fenced or time-locked so I can check the child in and out in the comfort of my home, but haven't probed the application further.
