Peak season is when operations show their strengths and their gaps. Volumes are climbing, lines are running longer, and small problems that stay hidden the rest of the year start to cost real money. Plenty of them trace back to a code: a date printed wrong, a batch number missing, a barcode that scans perfectly but carries the wrong information.
Machine vision is a familiar sight on production lines, confirming a cap is on or a label is straight. Checking the code itself is a job it often isn't asked to do, and it's one of the most valuable. Picture a beverage line producing thousands of cans a day. No team, however good, can check every date and batch code by eye, and a single error can mean a faulty batch, a costly replacement or a product that can't ship.
Reading a code isn't the same as verifying itÂ
Machine vision can do three quite different things with a code, and many set-ups are only asked to do the first. Reading confirms that the code scans. Verifying grades its print quality against the ISO/IEC standards, which matters because a code that reads well on your line can still be marginal on a less forgiving scanner further along the supply chain. Checking the content confirms the code says the right thing: the correct product, date and batch for what's in front of it. A crisp barcode with the wrong date scans perfectly and is still wrong, which is why the last two jobs are where the real protection sits.
What AI is now addingÂ
The most interesting shift is in how machine vision copes with real-world print. Deep-learning tools can help read distorted, obscured or low-contrast characters and codes on curved, shiny or crumpled packaging, where rule-based vision struggles, and can flag a pack that simply looks wrong without being taught every possible fault. They can often be trained from a few dozen sample images rather than thousands, and newer devices make the call on the device itself in a fraction of a second, so the line keeps moving. That has made AI-assisted vision quicker to set up than it once was, which is a good reason to revisit a code-checking project that was shelved as too complex a few years ago.
There's reassurance for compliance-minded operations too. AI doesn't have to mean losing the paper trail. When each decision is stored with its image and result, every pack comes with a record you can show a customer or auditor, and a fast answer if questions ever arise.
Put together, the payoff is practical: mistakes stopped at the source, fewer costly replacements, compliance backed by evidence, more reliable track and trace, and a team freed from squinting at codes to manage exceptions and improve the line.
Why now
GS1's Sunrise 2027 initiative is steadily moving retail towards 2D barcodes, with the aim that point-of-sale systems can read them by the end of 2027, now a little over a year away. Those codes can carry batch and expiry data within the code itself, which means more to get right, and a stronger case for verifying codes, not just reading them. With peak season in full swing, now is a good time to plan, and the quieter weeks that follow are a good time to pilot.
Where to startÂ
1. Pick the line or process where a code error would cost you most.
2. Find out whether your current set-up only reads codes, or also verifies them and checks their content, and whether it reads 2D codes today.
3. Make sure results and images are logged, so you have evidence when you need it.
4. Use the post-peak lull to pilot on one line, then scale what works.
