Walk down any UK high street and you’ll see them: little black-and-white squares on shop windows, café counters, menus, vans and estate agent boards. QR codes went from novelty to infrastructure in a few short years — and for a small business, they’re one of the cheapest marketing tools ever invented. Free to make, free to print, and they turn a passing glance into a website visit.
But most business QR codes are an afterthought: tiny, grey, linking to a homepage nobody asked for. Here’s how to use them properly — where to put them, what to link, and the mistakes that make them unscannable — plus a free tool that makes them right.
Why QR codes work for small businesses
A QR code removes exactly one thing: typing. Nobody types a web address from a van driving past. Nobody carefully copies a Wi-Fi password from a framed card without sighing. Every character a customer has to type is a customer you lose — a scan replaces all of it with one camera-point.
They cost nothing beyond the printing you were doing anyway, they work on every modern phone with no app to install, and unlike a web address on a flyer, you can point them at exactly the right page: not “our website”, but the booking page, the menu, the review form.
The placements that actually earn their keep
The shop window and the front door
Your window works 24 hours a day; your staff don’t. A QR code on the glass linking to opening hours, the menu or the booking page turns foot traffic after closing time into enquiries by morning. Make it big — people scan windows from the pavement, not from centimetres away.
The till and the counter
This is prime real estate: a customer standing still, phone in hand, with thirty seconds to kill. Link it to your Google review page and ask for the review while the experience is fresh — or to a loyalty sign-up, or today’s special. One scan beats a printed “please review us” card every time.
Menus, tables and waiting rooms
Cafés and salons already know this one, but go beyond the menu: a table QR that joins guests to the Wi-Fi (no more password spelling), or a waiting-room code linking to your price list and booking page. Boredom plus a phone is an opportunity.
The van and the uniform
A van is a moving billboard seen from metres away — so the code must be large (think A4 at minimum) and link somewhere worth visiting: the quote form, not the homepage. Same logic for workwear and site boards on trades jobs.
Business cards and flyers
A card has room for one link; a QR code carries six. Put the code on the back linking to your booking page or portfolio, and keep the front clean. On flyers, link to the specific offer on the flyer — never make someone hunt for it on your homepage.
Receipts and packaging
The sale is done; the relationship isn’t. A receipt QR linking to reordering, a how-to video or review page catches customers at peak goodwill. E-commerce parcels: a card in the box linking to setup guides cuts support messages.
What to link (hint: rarely the homepage)
The golden rule: link to the page that completes the thought. Window code → opening hours or booking. Van code → quote form. Till code → review page. Packaging → setup guide. Every extra click between scan and action loses people, so the destination page must also work flawlessly on a phone — a QR code that opens a desktop-only page is worse than no code at all.
Two more rules. First, link to pages you plan to keep: a printed QR code can’t be edited later, so never point one at a limited-time offer page you’ll delete. Second, keep the destination short and simple — if the page needs scrolling and pinching to use, fix the page before printing the code.
Five mistakes that make QR codes unscannable
- Too small. The number-one killer. Minimum 2 × 2 cm for hand-held items, much larger for anything scanned at distance. Print a test and scan it yourself before the full run.
- Weak contrast. Grey on white, brand pastels, or a “stylish” inverted code — phones read dark-on-light. If your colours are close together, it won’t scan reliably.
- No quiet zone. The plain border around the code isn’t decoration; scanners need it to find the edges. Don’t crop it, don’t fill it with pattern.
- Blurry or damaged prints. Low-resolution images, stretched aspect ratios and scratched signage all break scanning. Use a high-resolution PNG or SVG, never a screenshot of a screenshot.
- Linking to the wrong place. A code that opens your homepage when the flyer promised 20% off teaches customers not to scan your codes again.
Make yours in 4 steps
You could wrestle with a random generator that watermarks everything and holds your downloads hostage. Or use ours — free, no account, no watermark:
Step 1 — Pick what it should do
Choose Website, Text, Email, Phone, SMS or Wi-Fi. For a till code, that’s your review page link; for a café counter, the Wi-Fi tab with your network name and password.
Step 2 — Fill in the boxes
Type the link or details — the preview updates live as you type, so you see exactly what you’re getting. The tool adds the https:// if you forget it.
Step 3 — Style it (carefully)
Set your brand colours, but watch the contrast warning: if the tool flags your combination, listen to it — it’s telling you phones will struggle. Keep the quiet zone on.
Step 4 — Download and test
Grab the PNG (up to 2048 px for print) or the SVG for your designer. Then the non-negotiable step: print one, scan it with your own phone, in real light, at real distance. Only then print five hundred.
FAQs
Do QR codes expire?
No — a QR code is just your information encoded as a pattern. There’s no subscription or renewal. It keeps working as long as the page or detail it contains still exists, which is why you should link to permanent pages.
Do customers need a special app to scan?
Not any more. Every iPhone and Android phone from the last several years scans QR codes with its built-in camera — point, tap the notification, done.
Can I put my logo in the middle of a QR code?
You can, but it damages readability — the logo covers data modules. If you must, use the highest error-correction setting and test-scan extensively. For most small businesses, a clean code next to your logo works better than a compromised code under it.
How do I track scans?
The code itself doesn’t count scans. The practical workaround: point it at a dedicated landing page (e.g. yoursite.co.uk/scan-offer) and watch that page’s visits in your analytics — you’ll know exactly how the code is performing.
A good QR code is a tiny bridge between your physical presence and your website — and it costs you nothing but a few minutes. Make one that actually scans, put it where customers already stand still, and point it somewhere worth visiting.
