Kernel, the largest grain storage operator in Ukraine, says a lorry can now pass through one of its elevators, entry barrier to exit barrier, without a sheet of paper changing hands. The company set out the ten-year route to that point in a partner article on the Ukrainian technology site dev.ua in September 2026, so the claims are its own account rather than an audited result.
An elevator in this sense is not a lift. It is a grain intake, storage and handling complex: discharge pits, drying and cleaning plant, silos and a laboratory. Kernel runs around 30 of them with 2.2 million tonnes of combined storage capacity, which makes harvest intake a queueing problem before it is anything else.
Ten years ago it ran on paper coupons
Kernel describes the mid-2010s procedure as linear and analogue. A guard registered the vehicle and handed the driver a paper coupon to carry on foot to the weighbridge operator. A laboratory technician walked out to the lorry, took a grain sample by hand and carried it back to the lab, where quality was written down. The driver left the cab several times per visit and, in the company’s phrase, walked in circles.
Why a card rather than a mobile app
The first fix was an NFC card issued against the trip. NFC is a short-range contactless technology working at 13.56 MHz in the HF band, and cards of this type are ISO/IEC 14443 contactless smart cards, the same family as a travel ticket or an access badge. The driver taps the card at the gate and the system creates the record.
The reason for choosing a card is the interesting part for anyone who designs field credentials. Kernel says that when it decided, there was no way to send information from the fields over mobile internet, and that constraint settles the architecture. With no connectivity where the trip starts, the credential cannot be a pointer to a cloud record, so it has to be the record: the card carries the driver, the vehicle and the crop being hauled. The reader reads data rather than looking it up.
The company says it now uses QR codes and barcodes alongside the cards rather than instead of them. Once there is connectivity at the gate, a printed code is cheaper per movement and identifies a booked trip just as well. The card keeps its edge where the credential has to be issued with no signal, or survive a harvest season in a lorry cab. Mixed estates of this sort are normal in logistics, and usually a sign that someone matched the carrier to the conditions.
Cameras, automatic weighbridges and a sampling arm
The second stage closed off the steps that were left. Cameras read number plates on entry and exit. Automatic weighbridges weigh the vehicle and push the figures straight into Kernel’s accounting systems, with no weighbridge operator in the loop and, the company says, no scope for misreading or manipulating them. Display boards at the intake pits show the driver his instructions from the cab.
The step Kernel calls the most telling of the lot is unmanned weighing. A mechanical arm enters the lorry bed, takes the grain sample and passes it to the laboratory with no human contact, and the analysis syncs into the same systems automatically. The queue that formed while a technician walked from vehicle to vehicle has gone, and with it the ceiling that put on the weighing complex’s throughput.
The electronic queue, and the wartime case for it
Vehicles bunching up was the real constraint, so drivers register in advance and the system allocates an arrival slot and prioritises traffic. The same data tells Kernel how heavily loaded each site is, which turns a queue manager into a planning tool. In wartime it does something else as well: a cluster of stationary lorries is a target, and booked slots break up the cluster. The last piece, added in 2025, was the eTTN, the electronic consignment note, signed digitally.
What it cost, and what Kernel says it got
One automated platform, meaning the weighbridge plus the registration system, costs roughly 10,000 US dollars, installed and configured by Kernel’s own teams, and across around 30 sites the company says each one pays back quickly. It reports shorter idle time, faster turnaround and less room for fraud, with the throughput of the intake pit now the only bottleneck left. Drivers were suspicious at first, Kernel says, but the questions stopped after a few trips: “Previously they stood at the checkpoint for hours. Now they wait in a cafe outside the town, drive in and go through the whole process without queues.”
Kernel also cites TransitHUB for transport flows at production sites and field monitoring across 7,000 units of machinery. The elevator work has the clearest read-across for anyone running NFC credentials where the signal runs out.
