QR Auth is a system which helps anyone with a smartphone to ensure that items within the home or business are checked within agreed times set by the user. Users register on the website, app.qr-auth.com and create as many QR codes for items that need to be monitored. The first time a user scans a QR code created by the system using the app, the devices unique ID is captured. Unregistered devices are provided options specific to them.
