I was told they have QR codes, and then we going to use laser scanners to scan the QR code and from there, you can load the passcode that is embedded between the top sheet and sponge, visible with a special ITTF Mi5 glasses, and then using a special KGB tag to unlock the master key and they can match the authorization code while checking online for LARC with a bad internet connection.
