GreenCheck enables you to check quickly and easily whether a person to be checked may be granted access or entry into Austria. The check is carried out by scanning the digital or printed EU-compliant QR code. Clarity quickly: If the person is authorized to enter based on the rules of the COVID-19 opening or entry regulation, you will receive the result "Examination valid". If this is not the case or the scanned QR code is unsuitable as proof of access, you will receive the scan result "Check invalid".
