Sanai Authenticator is an identification app made in South Tyrol. The app is part of the Sanai system and acts as a medium for identification. After a user has registered in the app, an anonymous QR-code is generated, which is used to identify himself at the Sanai thermal scanner. This QR code is the digital ticket of the user and can be used wherever there is a Sanai scanner installed. The app has been developed and published in full respect of the privacy of the user and the legislation in force
