The digital vehicle registration document (DFZ) is a digital version of the vehicle registration certificate that can be used in the i-Kfz app on your device. With the i-Kfz app, vehicle owners can view, update and, if necessary, share their vehicle registration document (Zulassungsbescheinigung Teil I (ZB I)) anytime, anywhere. This facilitates access to important vehicle data and reduces the amount of paperwork required. The app also offers a secure and user-friendly way to manage vehicle registration certificates digitally. App functions: ADD: Vehicle owners can have a DFZ issued either using the eID function or by scanning a QR code in the app. There are several options for obtaining a QR code: QR codes are provided both on site, during the registration process or on request, as well as when registering online. UPDATE: The validity and current status of the digital vehicle registration document are automatically checked when the app is opened. The i-Kfz app also offers automatic updates, such as reminders of upcoming periodic technical inspections. SHARE: With just a few clicks, the vehicle owner can generate any number of shared versions of a DFZ and share them with third parties via link or QR code for permanent or temporary use. VIEW: With the help of a user-friendly display, you can view your vehicle and owner data at any time, even without an internet connection, and present it during a traffic check or periodic technical inspections, for example. DELETE: You can delete the DFZ and its shared versions in the app yourself. The i-Kfz app is constantly being developed.
