iButton Reader for Fleet Vehicles — 1-Wire Driver ID
What is an iButton Reader?
An iButton reader is a compact 1-Wire device that connects to compatible GPS trackers to enable driver identification across fleet vehicles. Each driver carries a small stainless steel iButton key — when touched to the reader, the GPS tracker logs the driver's unique 64-bit ID alongside every journey. This makes it easy to attribute mileage, hours, speed events, and route history to individual named drivers without manual log sheets or driver self-reporting.
How 1-Wire Driver ID Works
1-Wire is a serial communication protocol that transfers data over a single wire. Teltonika and Queclink GPS trackers include a dedicated 1-Wire input for this purpose. When a driver presents their iButton key, the tracker reads the unique ID and transmits it alongside every GPS position report. Your fleet management platform links that ID to a named driver profile, so every trip is attributed to the correct driver automatically — no manual input required.
Compatible GPS Trackers
Our iButton readers are compatible with the full range of Teltonika and Queclink GPS trackers that include a 1-Wire interface. This includes the for example the Teltonika FMB125, FMB130, FMC650, FMC130, FMC234, and the Queclink GV620MG, GV350MG, GV75MG and more. All use the standard 1-Wire yellow wire connection. Contact us to confirm compatibility with your specific device.
iButton Reader vs PIN Keypad Driver ID
Both iButton and PIN keypad systems identify drivers at the start of each journey. An iButton uses a physical key fob the driver carries; our driver ID keypads allow a 4–8 digit PIN to be entered instead. PIN keypads are increasingly preferred in modern fleets — there is no physical key to lose or forget, and the keypad can act as a vehicle immobiliser, preventing the engine from starting until a valid PIN is entered. We supply both systems and can help you choose the right approach for your fleet.
