Features
Specifications
Accessories
Remote Locking and Unlocking
The vehicle locks and unlocks via a mobile app or RFID badge, with no physical key. This completely eliminates key handovers, streamlines rentals, and enables fully self-service operation.
Driver Identification
Each driver is automatically identified (badge, smartphone, or NFC), ensuring full traceability of vehicle use, preventing unauthorized borrowing, and simplifying shared fleet management.
Real-Time Tracking
Instantly view your vehicles’ position, activity, and alerts for more responsive day-to-day management.
Immobilizer
The system blocks the vehicle from starting unless a valid booking is active or an authorized badge is detected on board. This prevents unauthorized use, theft, and unplanned departures.
Custom Alerts
Technical alerts and low levels (fuel, battery, vehicle anomalies, etc.) are detected and reported in real time. Combined with our predictive maintenance module, these alerts allow you to act earlier and prevent breakdowns during rentals.
Comprehensive Telematics Data
The device automatically reports key data: mileage, trips, vehicle status, critical levels, and technical events. Maintenance and usage tracking become simple, reliable, and free of manual data entry.
Connected Services
Access an ecosystem of connected services, such as fine management and insurance renewal tracking, to enrich your fleet management.
