Driver ID Keypad Compatibility Guide: Which Keypad Works with Which GPS Tracker?

Choosing the right driver identification keypad for your fleet means more than selecting a price point. The keypad must be compatible with the GPS tracker already installed in your vehicles — matching its communication interface, connection protocol, and I/O configuration. This guide covers which of our keypads work with which trackers, what connection method is required, and how driver ID data flows from keypad to fleet management platform.

GPS tracker technology — driver ID keypad compatibility guide

How Driver ID Keypads Connect to GPS Trackers

Most driver identification keypads connect to a GPS tracker via one of two interfaces: 1-Wire (a single-wire digital protocol used by Teltonika and other manufacturers) or RS232/RS485 (a serial interface for more advanced data exchange). Some newer models support Bluetooth Low Energy (BLE) for wireless connection to BLE-enabled trackers. The tracker's technical specification will list which driver ID interfaces it supports. Our keypads are clearly labelled with their connection type, and we can advise on the correct pairing for your tracker model.

Keypads Compatible with Teltonika Trackers

Teltonika FMB and FMC series trackers support driver ID input via the 1-Wire protocol on the 6-pin I/O connector. The FMB920, FMB140, FMC920, and FMC130 are all confirmed compatible with our wired PIN keypads including the EC-19521, GC-2673, and STL-1307 models. Driver ID is configured in Teltonika Configurator under the I/O element settings — our team can provide the exact configuration parameters for each supported model.

Keypads Compatible with Queclink Trackers

Queclink GV and GL series trackers support driver ID via their accessory input port. The GV620MG, CV200, GV57MG, and other GV series models are all tested and confirmed compatible with our wired PIN keypads. Driver ID data is transmitted to your fleet management platform alongside GPS position data, enabling the same per-driver reporting capability available with Teltonika devices.

Keypad Models: Which One to Choose?

We stock three main driver identification keypad models for fleet deployment. The EC-19521 is a compact 10-digit PIN keypad ideal for cars, vans, and light commercial vehicles — a straightforward, cost-effective option for standard fleet installations. The GC-2673 is an IP68-rated weatherproof unit with an integrated NFC reader, combining PIN entry and contactless card scanning in a single device — ideal for trucks, buses, and outdoor plant where both methods may be required. The STL-1307 is a slim-profile unit for installations where cab space is limited. All models are available from UK stock with tracker-specific wiring diagrams.

What Happens When a Driver Enters Their PIN?

When a driver enters their PIN, the keypad sends the driver identifier to the GPS tracker. The tracker logs the driver ID in its memory and includes it in every subsequent data packet transmitted to the fleet management platform. The platform attributes all trip data — location, speed, events, fuel consumption, idling — to that named driver for the duration of the login session. When the driver logs out, or the ignition turns off depending on configuration, the driver ID session ends. This creates a complete, timestamped, auditable record of who drove which vehicle, when, and how.

Can I Retrofit Driver ID to an Existing Tracker?

In most cases, yes. If you already have Teltonika or Queclink trackers installed, adding a driver identification keypad is a retrofit installation that connects to the tracker's existing accessory port. No tracker replacement is needed — only the keypad is added. Installation typically takes 30-60 minutes per vehicle depending on cab layout. Our team can provide the correct wiring instructions and Teltonika Configurator or Queclink platform settings needed to activate driver ID on your existing hardware.
