Authorized Driver Tool: Only Approved Drivers Can Start the Vehicle
Driver ID tells the fleet who drove; the Authorized Driver Tool decides who can. A whitelist per vehicle, an NFC reader in the cab and a relay on the starter circuit mean a vehicle starts only for a driver on its list — which is how fleets enforce licences, certifications and vehicle assignments without a key cabinet.

Identification Versus Authorization
An NFC driver ID reader on the GO device's IOX port records which driver tapped in, so every trip is attributed to a person and the scorecards, hours and reports follow the driver rather than the truck. That is identification. Authorization is the next step: the vehicle does not start unless the driver who tapped is on that vehicle's approved list. The Authorized Driver Tool adds the list, and a relay kit on the starter circuit adds the enforcement.
How It Works
Each vehicle in MyGeotab carries a whitelist of drivers. The driver taps their NFC key on the reader; the GO device checks the ID against the list; if it matches, the relay closes and the vehicle starts normally, and the trip is logged to that driver. If it does not, the vehicle does not start and the attempt is recorded. The list is maintained in the platform, so a driver whose licence class, medical or certification lapses is removed from the vehicles that need it with a click, and the vehicle enforces the change on the next tap.
Where It Is Used
Fleets whose vehicles need specific credentials — a class of licence, a forklift or aerial-lift certification, a hazardous materials endorsement — use it to make the credential a condition of starting rather than a policy on paper. Shared pools use it to keep the unassigned van from becoming everyone's van. Rental and equipment fleets use it to stop machines running under an operator who is not on the contract. Municipalities use it where a collective agreement assigns vehicles to classifications.
Installation
The IOX-NFCREADERA plugs into the GO device's expansion port and mounts in the cab; the relay kit is wired into the starter circuit by an installer, with an override procedure for emergencies. High Point GPS installs the reader and relay and configures the whitelists for fleets in Quebec, Ontario and the northeastern US.
Frequently asked questions
What is the Authorized Driver Tool?
A MyGeotab configuration that pairs an NFC driver ID reader with a starter relay so a vehicle starts only for drivers on its approved list.
How is it different from driver ID?
Driver ID records who drove. The Authorized Driver Tool decides who can start the vehicle, enforced by a relay.
What happens when an unlisted driver taps?
The vehicle does not start and the attempt is logged in MyGeotab.
Can a driver be removed quickly?
Yes. Removing them from the list in MyGeotab takes effect on the vehicle's next start attempt.
Is there an emergency override?
Yes. The installer provides an override procedure for situations where the vehicle must move without a listed driver.
