Small Print, Big Signal: Turning UK Till Slips into Trackable Link Space

A receipt is handed over, glanced at, and often shoved in a pocket or bag. It is not a glossy campaign asset. That is exactly why it can work. No cookies to accept, no pop-up to dismiss, no algorithm deciding whether the message gets seen. Just a small piece of paper with a web address on it — and, too often, a QR code that nobody tested properly.

At CutURL, we spend a lot of time on the unglamorous side of links: what happens when they are printed, scanned, shared and counted. Till slips are a good test of that discipline. They are cramped, they smudge, and they get printed by the thousand. But they also sit right next to the moment of purchase, which is a decent place to start a returns journey, a warranty sign-up or a loyalty prompt.

The till slip is a tiny screen with no scroll

Thermal receipt printers are not designed for elegant design. Many are monochrome, low-resolution and working with paper widths of 40mm or 58mm. Logos can turn to mush. Grey text can disappear. A long URL can wrap awkwardly and become impossible to type.

That means the link has to be short in the literal sense, not just the branded sense. A printed address like cuturl.co.uk/returns is readable at a glance. A 90-character tracking URL is not. If you are printing a QR code, give it room: a decent quiet zone around the code, enough physical size to scan from a phone at arm’s length, and high error correction so a crease or a smudge does not kill it.

And always print the human-readable short link next to the QR code. Some people will not scan. Some phones will not cooperate. Some store lights will glare off the paper. The plain text is the fallback, not a nice-to-have.

Decide what the receipt is actually for

A receipt campaign can easily become a queue of competing asks: join the loyalty scheme, complete the survey, register the warranty, start a return, follow us, download the app. That is too much for a scrap of paper.

Pick one job per receipt layout. If the main job is returns, make the returns portal the destination. If it is warranty registration, send people there. If it is a feedback survey, do not bury it under three other buttons on the landing page. If you need to promote more than one thing, use separate receipt versions or separate short links, not a vague link that sends everyone to the homepage.

This is also where store-level tracking gets interesting. If receipts are printed centrally, one link may be all you can manage across every branch. If local printing is possible, a distinct short link per store — or a store code appended to the destination — can give you cleaner numbers. Be honest about which model you are using before you promise branch-level reporting.

Thermal reality check

A short link that looks fine on a design proof can fail on paper. Test with the actual printer, the actual roll and the actual size. Scan the code at 20cm, 30cm and 50cm. Try it under harsh shop lighting and with a phone camera that is not brand new. Crumple the receipt, smooth it out, and try again. If the code only works on a flat, pristine sample, it is not ready.

Keep the slug simple. Avoid characters that look alike in print — zero and the letter O, one and the letter I. Hyphens are fine in moderation, but a short, plain word is easier to read aloud when a customer asks a colleague what the receipt says. The person on the till should be able to point at the link and explain it in one sentence.

Store-level numbers without a data maze

Receipt campaigns often produce two kinds of measurement: how many people scanned or typed the link, and which store the receipt came from. Those are not the same thing. A generic link gives you a campaign total. A store-specific link gives you a branch view, but only if the print process supports it.

If you cannot print different codes per store, do not fake precision in the report. Use the short-link data for what it is — a campaign-level signal — and pair it with point-of-sale context if you have it. If you can print locally, keep the naming convention boring and consistent: store code, campaign code, date. Future you will be grateful.

Also check the destination. A receipt link often has a long life: returns windows can run for 28 days or more, warranty sign-ups can happen weeks later. Do not let the short link expire before the paper does. Test the redirect after a month, not just on launch day.

Accessibility is part of the print spec

A QR code is not accessible to everyone. Blind and low-vision customers, and plenty of others, need a readable short URL and a clear label. Write the instruction in plain English: “Returns: cuturl.co.uk/returns”. Avoid all-caps blocks, tiny grey text and clever slogans that hide the action. If the destination asks people to download an app before they can do anything useful, rethink it.

The landing page matters too. It should load quickly on a phone, work on a weak connection and not rely on a hover state or a tiny tap target. If your receipt campaign is UK-wide, check that the destination handles the basics: clear returns policy, accessible forms, and a privacy notice that explains what happens to the data.

A pre-rollout checklist for receipt links

• Print a sample on the real till roll, at the real size, on the real printer.
• Scan the QR code with at least three phones, including an older handset.
• Try the code after folding, crumpling and a light smudge.
• Check the plain-text short link for ambiguous characters and line breaks.
• Confirm the destination works on mobile data, not just shop Wi-Fi.
• Make sure the short link will outlive the returns or warranty window.
• Decide whether tracking is campaign-level or store-level, and say so in the report.
• Brief till staff on what to say if a customer cannot scan the code.
• Run a small pilot in a handful of branches before rolling out to every till.
• Review scan rates and typed-link rates separately; they tell different stories.

A receipt will never be a billboard in the traditional sense. It is too small, too functional and too likely to end up at the bottom of a bag. But that is fine. A clean short link, a tested QR code and a destination that does one job properly can turn that little piece of paper into a measurable hand-off — and that is more than most receipts manage today.
