How it works
No inspection. No start. Here's how.
A small Interlock keeps a machine from starting until the operator completes the pre-start on their phone. Every check and defect is recorded and can't be edited afterwards, so you can prove it happened.
The machine won't start until it's checked
A relay fitted by a licensed auto electrician sits in the starter circuit, or the operator-presence circuit where that suits the machine, and holds it open until a completed pre-start unlocks it.
Proof you can stand behind
Every check and every defect is written to an append-only record that nobody can edit after the fact. The reports a client, an auditor or the regulator asks for are ready when you need them.
Defects don't get lost
A failed item raises a defect the whole team can see, from the moment it is reported to the moment it is closed. When the failed item is critical, the machine's pre-starts fail until that defect is closed.
Pre-starts on a phone, in the field
A paper checklist can be signed without anyone walking around the machine. Operators scan the GoTag and work through the checklist with photos, and pre-starts keep working with no coverage.

Step by step
From fitting to proof.
Fit it to the machine
A GoTag goes on every machine: a durable label with a QR code and an NFC chip. Add an Interlock to any machine you want held until it has been checked. Your own licensed auto electrician fits it.
A GoTag on its own still gives you pre-starts, without the lockout.
Read the installation guideGoTag
Outside, near the cab door or step. It's meant to be found.
Interlock
Wired in and out of sight, in the cab or engine bay.
Scan the GoTag
The operator scans the machine's GoTag with their phone, by QR code or NFC tap. That identifies the machine and loads its checklist, so the right machine gets inspected.

Work through the checklist
The app guides a walk-around. Each item passes, fails or doesn't apply, with photos taken along the way. A typical check takes two to five minutes.
Critical items can't be skipped.
Pre-starts keep working with no coverage.
A pass unlocks. A critical fail doesn't.
When the check passes, the app sends a signed Bluetooth command to the Interlock and the machine can be used.
A failed item raises a defect. If the item is critical, or the machine has been taken out of service, the check fails and the machine stays locked.

The office sees it
Every machine. Every check. One place. The result syncs with the operator, time, location, checklist version, defects and photos. With no coverage, it syncs once the phone is back in range.
Proof when you need it
Every check and every defect sits on an append-only record that nobody can edit after the fact. The reports a client, an auditor or the regulator asks for are ready when you need them.
Good to know
What to expect from it.
Fail-START
On power loss the relay defaults to letting the machine start — operators are never stranded. The Interlock is a compliance-enforcement tool, not a safety-rated isolation device.
Unlocks expire
An unlock ends with the check's validity window: 11 hours by default, 24 at most. It also re-locks once the machine has been switched off for a set time (15 minutes by default).
Emergency bypass
Hold it for ten seconds for the emergency bypass, where the button bypass is enabled.
