The CHECK-AT app is your digital companion for an easy verification of the new Austrian passport and ID card. With the app, check the QR code and other security features on the new passport generation easily and securely. Simple verification - without any need for technical expertise: In addition to the convenient QR code check, the CHECK-AT app guides you step by step through verifying individual security features on the new Austrian passport and ID card. Using examples, the CHECK-AT app allows you to thoroughly examine the digital and physical security features of the new passport generation and ID card – even without any special expertise. Local verification without retrieving personal data from the internet: During the QR code check, the information contained in the QR code is only displayed on the verifying device. The relevant information is directly included in the QR code and is not retrieved from a database. The app connects to the internet during the startup process to check the availability of new certificates necessary for the correct and secure verification of the QR code. If new certificates are available, the app automatically downloads them to the device in use. Furthermore, the app does not connect to the internet at any other time. No personal data is retrieved from the internet or uploaded to the internet.
