A Carteira Digital de Trânsito (CDT) is the digital evolution of CNH Digital. It is now possible to download the digital version of the Certificate of Registration and Licensing of Vehicles (Documento do Veículo) and have it as a mobile document to be used as a reference for any administrative or legal process.

- Convenient sharing of data (PDF export with a digital signature (.P7S) in the ICP-Brazil standard with legal validity in accordance with MP 2.200-2/2001). This eliminates the need for document printing and/or scanning and does away with cartorial authentication;
- Its validity, dependability, and integrity may be easily verified using the Vio program. Download the Vio app, then simply point the reader at the QR Code on your digital document to accomplish this.
