Authorized Driver Tool: Only Approved Drivers Can Start the Vehicle

The Authorized Driver Tool adds NFC driver ID that lets a vehicle start only for approved drivers, with a cab reader and a relay on the starter circuit.

How Is the Authorized Driver Tool Different From NFC Driver ID?

The Authorized Driver Tool keeps a vehicle from starting unless the driver who taps in is on that vehicle's approved list, and a relay on the starter circuit enforces it. Plain NFC driver ID only identifies: a reader on the GPS tracking device's IOX port records who tapped in, so trips, scorecards and hours follow the person instead of the truck.

How Does the Authorized Driver Tool Work?

Every vehicle in the High Point GPS platform carries its own whitelist of drivers. The driver taps an NFC key on the reader and the GPS tracking device checks the ID against the list. On a match, the relay closes, the vehicle starts and the trip is logged to that driver. Without one, the vehicle stays off and the platform records the attempt. When a driver's licence class, medical or certification lapses, you remove them from the vehicles that require it with a click, and the change applies at the next tap.

Where the data goes: the engine bus and sensors feed the GPS tracking device, the cloud applies the fleet's rules, and the High Point GPS platform or the API hands it to your systems.

Which Fleets Use It?

Fleets whose vehicles need a specific credential (a licence class, a forklift or aerial-lift certification, a hazardous materials endorsement) use it so the engine won't start for anyone who lacks it. Shared pools use it so the unassigned van doesn't turn into everyone's van. Rental and equipment fleets use it to stop machines running under an operator who isn't on the contract, and municipalities use it where a collective agreement assigns vehicles by classification.

Set the Policy Before You Install the Relay

The relay enforces whatever list you maintain, so get the list right before the relay goes in. Write down three things first. Which credential does each vehicle class require, and who confirms it? How does a driver get added or removed, and how fast after a licence or certification changes? And what is the override procedure when a vehicle has to move and the authorized driver isn't there? The override is the step fleets forget. A supervisor code, a spare fob held by dispatch or a time-limited unlock from the High Point GPS platform all work. A truck stuck in a flooded yard because its only authorized driver is on vacation does not. High Point GPS sets up the override with the whitelist and tests it before the installer leaves.

Installing the NFC Reader and Starter Relay

The IOX-NFCREADERA plugs into the GPS tracking device's expansion port and mounts in the cab. An installer wires the relay kit into the starter circuit and sets up an override procedure for emergencies. High Point GPS installs the reader and relay and configures the whitelists for fleets across Canada and the United States.

Frequently asked questions

What is the Authorized Driver Tool?

It is a High Point GPS platform configuration that pairs an NFC driver ID reader with a starter relay, so a vehicle starts only for drivers on its approved list. A driver taps an NFC key, the GPS tracking device checks the ID against that vehicle's whitelist, and the engine starts only on a match.

How is it different from driver ID?

Driver ID records who drove, and the Authorized Driver Tool decides who can start the vehicle. Driver ID attributes each trip and report to the person who tapped in. The Authorized Driver Tool adds an approved list for each vehicle and a starter relay that keeps the engine off for anyone not on it.

What happens when an unlisted driver taps?

The vehicle does not start, and the High Point GPS platform logs the attempt. The relay on the starter circuit stays open because the ID doesn't match that vehicle's whitelist, so you get a record of who tried to take a vehicle they weren't approved to drive.

Can a driver be removed quickly?

Yes. Removing a driver from a vehicle's list in the High Point GPS platform takes effect on that vehicle's next start attempt. When a licence class, medical or certification lapses, you take the driver off the affected vehicles with a click, and each vehicle enforces the change at the next tap.

Is there an emergency override?

Yes. The installer provides an override procedure for when the vehicle has to move without a listed driver, such as a supervisor code, a spare fob held by dispatch or a time-limited unlock from the High Point GPS platform. High Point GPS tests the override before the installer leaves.
