Container Number Recognition (CNR)
Container numbers carry their own checksum. Most gates ignore it. Ours don't.
Manual gate clerking costs minutes per truck and produces mis-keyed container numbers at dusk, in rain, at shift change. Each wrong digit travels downstream until it surfaces as a yard dispute or a billing argument with a shipping line — weeks later, when it is expensive to unwind.

How we solve it
OCR that validates before it trusts
ISO 6346 numbers include a check digit computed from the other characters. Our gates do that arithmetic on every read — a failed check means a retry or a flagged lane, never a wrong number written into your system.
Matched against expected movements
The number is checked against bookings or delivery orders before the barrier lifts. Unexpected boxes get a human decision, at the gate, while the truck is still there.
Commissioned lane by lane
Depots do not close for IT projects. We tune and cut over one lane at a time, with the manual process still available until the read rates prove themselves on your traffic.
The yard system knows in real time
Movements land in your operations system as they happen. The audit trail assembles itself, with photographs.
Container Number Recognition (CNR) is just one of the things we do.
Most clients only find out when we tell them: the same team designs, supplies and maintains everything on this list — under one contract, one invoice.
The full A to Z
And we supply the hardware too — A to Z. PCs, laptops, servers, printers, network gear, CCTV, firewalls, licences: 7,000+ products with itemised quotations in one working day, on our own platform.
