The Car-Pass is printed on special paper that has a hologram on it to make forgeries and fraud much more difficult. Do you have a suspicion that the document is a forgery or that the odometer readings are incorrect? Scan the QR code or fill in the identification number here. What you will see on the screen should match the data on the document. If not, or if you get an error message, there is a high chance the document is a fraud or expired some time ago. A Car-Pass is only valid for two months. You will find the validity date at the top right of the document.
