Carteira Digital de Trânsito is the official Brazilian app for carrying your driver's license in your pocket, as well as all your official vehicle information. Using Carteira Digital de Trânsito is as valid as keeping physical versions of your car's papers and your driver's license on hand. Thanks to this app, if you don't have your wallet with you or you need to check some technical data related to your vehicle, you can easily do so from your smartphone.

As a replacement for physical paperwork, Carteira Digital de Trânsito is a valid way to present your documents to officials whenever you need to identify yourself. For example, it's completely valid to show it to a policeman if you have been stopped while driving.
