RFID Driver Identification + 4G Vehicle Tracking — GT902K

GT902K is a hardwired 4G vehicle GPS tracker with a built-in RFID/NFC card reader for driver check-in and vehicle-use traceability. It combines GPS/AGPS/LBS/Wi-Fi positioning, 9–90V input, RS232 expansion, alarms, blind-spot supplementation and supercapacitor power-off protection.

All-in-One Card Swipe & Positioning Device

The built-in RFID/NFC reader lets drivers identify themselves without an external card reader. This leaves the RS232 interface available for compatible peripherals such as fuel or temperature sensors.

Reusable Driver Cards

Card-writing support allows a blank or reassigned RFID card to be updated when driver information changes, reducing the need to issue a new physical card for every personnel change.

Built-in Supercapacitor

GT902K supports DC 9–90V vehicle power. A built-in supercapacitor can keep the tracker operating briefly—about 10 seconds—after external power is disconnected so a final event/location report can be sent. GT902K does not use a backup battery.

Bulk 4G RFID GPS Trackers Ready-to-Ship

GT902K combines driver identification and vehicle positioning in one device for fleet, rental and commercial vehicle deployments. GreatWill supports OEM/ODM customization and compatible platform integration.

The RFID/NFC reader is built into the tracker, so drivers can swipe a compatible card directly without installing a separate external card reader.

With a compatible backend, card-swipe records can be associated with the vehicle and driver-use period, helping managers trace who used a vehicle and when.

Yes. The card-writing function allows compatible cards to be rewritten when driver assignments change.

GPS/AGPS is used for satellite positioning, while LBS and Wi-Fi data can assist in obstructed or indoor environments where GNSS signals are weaker.

Blind-spot data supplementation stores tracking data when communication is unavailable and uploads it after the network connection returns.

The built-in supercapacitor can supply roughly 10 seconds of short-term power for a final report. GT902K does not contain a backup battery.
