Zona Azul SJC is a mobile application that replaces the paper parking cards in São José dos Campos. It allows users to purchase and activate parking cards using their smartphones. With this app, users can register for free, buy credits using their credit cards, and activate parking cards with ease and security, without having to expose the card inside their vehicles. Parking enforcement officers check the validity of the parking through electronic means by scanning the vehicle's license plate.

The app also comes with an alarm feature that reminds users of the expiration of their parking cards, helping them avoid fines. Zona Azul SJC follows the same rules as the paper parking card. Users should check the signage in the Zona Azul São José dos Campos area and activate their parking cards accordingly. Additionally, users can track their usage through the app's purchase and activation history.
