Fleet Management + Anti-theft Protection — GT902K

Wired Vehicle GPS Tracker. Combines efficient fleet management with robust anti-theft! Built-in NFC reader enables drivers to quickly check in/out via RFID card swipe, with real-time attendance data synced to the backend. Features multi-mode positioning (4G + GPS + LBS + AGPS), 9-90V wide voltage compatibility, plus blind spot data supplementation and overspeed alarm. Safeguards vehicles and simplifies fleet management.

All-in-One Card Swipe & Positioning Device

Most trackers on the market use external card readers via RS232. The GT902K features a built-in RFID card reading module for greater convenience, with the RS232 port reserved for connecting peripherals like fuel sensors and temperature sensors.

One Card for Multiple Users

Supports card writing function; comes with one blank card by default. Enables card rewriting when driver information changes—modify driver card data via SMS commands to realize one card for multiple users. Enter the card writing command, wait 2 seconds, place the card on GPS device, and it will automatically write the card and complete check-in.

How Does the GT902K RFID GPS Tracker’s NFC Attendance + Multi-Mode Positioning Address the Dual Needs of “Driver Management + Vehicle Tracking”?

Efficient Check-in, No More Hassle

Equipped with a built-in NFC card reader (paired with an FPC antenna), drivers can complete work attendance simply by swiping an RFID card when checking in and out. No manual registration or additional operations are required. It is suitable for high-frequency attendance scenarios such as fleets, ride-hailing vehicles, and rental cars, saving time costs.

Real-Time Data Synchronization & Controllability

Check-in records are uploaded to the backend in real time. Managers can remotely view drivers’ attendance times and corresponding vehicle matching status, eliminating issues like proxy check-ins, being late, or leaving early. Meanwhile, attendance data is bound to the vehicle usage period, enabling clear tracing of “who used the vehicle and when”.

Stable & Reliable, Adaptable to Diverse Scenarios

Relying on a hardware-level NFC module, the check-in response is fast and anti-interference. Combined with GPS device’s weather-resistant design (-20℃~+65℃), it can work stably even in harsh environments such as construction sites and outdoor areas, ensuring no loss of attendance data.

Multi-Mode Fusion, No Blind Spots in Positioning

Integrates GPS (AT6558R module) + AGPS + LBS + WiFi multi-mode positioning technology. GPS features fast response with cold start in 38s and hot start in 2s, accurately locking positions in open environments. In indoor/obstructed scenarios, it achieves assisted positioning through LBS (supports uploading of 6 groups of base station addresses) and WiFi (supports scanning of 30 groups of MAC addresses), eliminating positioning blind spots.

Complete & Traceable Trajectory

Supports corner reporting, stationary reporting, and blind spot data supplementation. Whether the vehicle is driving, parked, or passing through areas with weak signals, it can fully record the trajectory. Managers can remotely trace the vehicle’s driving route and stay duration, preventing issues such as private use and route deviation.

Abnormal Alert, Anti-Theft & Vehicle Protection

Combined with vibration alarm and geofencing functions, the system triggers real-time alerts when the vehicle encounters abnormal vibration (e.g., theft or prying) or deviates from the preset area. Equipped with a super capacitor that provides 10 seconds of backup power (to prevent disconnection due to power cut), it can still briefly upload positioning information even if the external power is cut off, helping track the vehicle and reduce the risk of theft or robbery.
