We have used QR codes for quick payments, to demonstrate our vaccination and now also for control access to a building.
I love it! It is simple and fast.
How it works?
1. The access control system administrator sends the code to the visitor via email or SMS.
2. The visitor just shows it on their smartphone display to a QR reader or video intercom at the building entrance.
There is no need to meet in person, hand over the RFID card and then return it again.
Once the administrator-set interval is over, the QR becomes invalid and inoperable
