NFCGuard - Smart Road Enforcement

Secure, fast, and corruption-free road checks—powered by NFC.

Comment

🚦 Inspiration

In Africa, road checks often remain manual and time-consuming, with significant risks of fraud and corruption. Law enforcement lacks modern tools to quickly verify the validity of documents and the identity of drivers.
NFCGuard aims to provide a secure, mobile, and tailored solution that uses NFC technology to digitize and enhance the reliability of these controls.

📱 What it does

NFCGuard is a mobile application designed to facilitate and secure road checks by combining NFC chip reading and access to official databases.

  1. 🔍 NFC Driving License Scan
    The driver presents their license, equipped with an NFC chip containing a unique identifier. The officer scans this license with the app, which queries a secure API to retrieve the driver’s information: identity, license validity, authorized categories, and history of any infractions.

  2. 🚗 Vehicle Crisis Card Scan
    The vehicle has an NFC card (called the "crisis card") also containing a unique identifier. By scanning it, the app retrieves via API the vehicle and owner data: registration, insurance, technical inspection, control history, etc.

  3. ✅ Cross-verification and Validation
    The app compares driver and vehicle data to verify if the driver is authorized to operate the vehicle. It checks document validity, vehicle condition, and regulatory compliance.

  4. ⚠️ Infraction and Sanction Management
    If one or more infractions are detected or noted by the officer (expired license, uninsured vehicle, etc.), the app allows to:

    • Select the observed infractions from a clear list.
    • Automatically generate an appropriate fine.

  5. 💸 Fine Payment
    The officer can record the fine payment directly through the app, with several options adapted to the local context:

    • Mobile payment via Wave or Orange Money (with integration or simulation of the payment gateway).
    • Cash payment, recorded manually.

  6. 📢 Additional Action Management
    If the vehicle must be immobilized or sent to impound, the officer can quickly trigger an alert directly from the app, automatically sending a message to the relevant impound service.

  7. 🗂️ Complete Traceability
    Every control is logged in the database with all the following information:

    • Identity of the officer who performed the control.
    • Identity of the driver and vehicle data.
    • Date, time, and precise geographic location of the control.
    • List of infractions observed.
    • Payment information (amount, method, status).
    • Additional actions (impound alert, etc.).

This traceability ensures transparency and reliability of the checks, enabling rigorous administrative follow-up and combating abuses.

🏗️ How we built it

  • Flutter application using flutter_nfc_kit for NFC chip reading.
  • Spring Boot backend exposing secure REST APIs, with a MySQL database modeling drivers, vehicles, owners, controls, and payments.
  • JWT authentication and HTTPS communication to ensure security.
  • For hackathon purposes, we used representative data embedded locally, anticipating future connection to official APIs of competent authorities (ministries, police, insurance).

🛠️ Challenges we ran into

  • Ensuring compatibility and reliable NFC reading across various devices.
  • Securing data exchanges between mobile and server without complicating user experience.
  • Accurately modeling the complex relationships between drivers, owners, and vehicles.
  • Providing robust operation even with limited network connectivity.
  • Integrating mobile payment methods in a realistic test environment.

🎉 Accomplishments that we're proud of

  • Smooth workflow allowing successive scanning of two NFC chips.
  • Complete and secure traceability of conducted controls.
  • Relevant integration of locally used mobile payment solutions.
  • Modular, secure, and scalable architecture.
  • User-friendly interface adapted to field constraints.

📚 What we learned

  • Clear distinction between driver and owner is a key project point.
  • Limiting data stored on the NFC chip to a unique identifier enhances security and eases update management.
  • Comprehensive traceability is essential to fight corruption and ensure trust.
  • Integration of mobile payments is a strong lever for effective sanctions.
  • Designing for field use requires balancing ease of use and technical robustness.

🚀 What's next for NFCGuard - Smart Road Enforcement

In a real-world context, NFCGuard will be able to connect to official APIs of national competent authorities to retrieve up-to-date data on drivers and vehicles.
We also plan to add complementary features such as facial recognition, a web dashboard for supervision, and automated infraction management.
