App-based enforcement works with a traffic officer checking, on a phone or tablet, whether the plate of each parked vehicle has an active parking session. Instead of the old paper ticket book, the officer uses an app connected to the same database where the driver registers payment through Digipare. They type in or scan the plate, the system instantly responds whether that car is compliant, and only then do they decide what to do. It all happens in seconds and is logged digitally.
The flow, step by step
- The officer walks the street and observes the vehicles parked in the Zona Azul area (Brazil's paid rotational street parking).
- In the enforcement app, they enter the vehicle's plate — typing it in or via automatic reading.
- The system queries the activation database in real time and returns the status: active, expired or never activated.
- If it is compliant, nothing happens. If it is not, the officer records the case with a photo, date, time and location.
- Depending on the city's rules, a notice/post-use fee is generated first (where the municipality adopts one) or the process goes straight to issuing the fine.
Why the app is fairer
The check is objective: either the plate shows as active, or it does not. This removes the subjectivity of paper and reduces errors. In addition, every check is logged, creating a chain of evidence (plate, image, time and place) that gives certainty both to the city and to the driver who needs to contest a fine.
What the officer sees on screen
| Information | What it is for |
|---|---|
| Plate checked | Identifies the verified vehicle |
| Activation status | Shows whether it is active, expired or absent |
| Activation time | Confirms whether the paid time is still valid |
| Location | Confirms the vehicle is in the regulated area |
The difference between payment and enforcement
These are two apps with different roles. Digipare is the driver's app, used to activate parking time and track the balance. The enforcement app is the officer's, used to check plates. The two talk to the same database — which is why, seconds after you activate through Digipare, your plate already shows as compliant to whoever is enforcing.
Practical tip
Activate your parking as soon as you stop and keep notifications on so you are warned before the time expires. Because the check is instant, keeping your activation up to date is what guarantees the officer's query always returns "compliant".
