QR codes for retail stores

In a shop the competition for a QR code is not another code — it is the customer simply typing your name into a search box, or walking out. So a retail code only works when it saves a real step: the size that is not on the shelf, the full description that does not fit on a label, the shop that is closed at 9 p.m. but whose window is still lit. Those are the codes that get scanned. A generic "follow us" sticker is not one of them.

The spots where a code actually gets scanned

Each of these is a moment of friction you can remove. If you cannot name the step a code saves, do not print it — unused codes train customers to ignore all of them.

Shelf labels: one code per product line, not per item

A code on the shelf edge should open the product page — sizes, colours, stock, reviews, the specification that never fits on a paper label. One code per product line is the right level: per individual item it becomes unmanageable, per category it is too vague to be useful.

Keep the encoded link short. Shelf labels are the smallest codes in the shop, and a long URL with tracking parameters makes the pattern denser and harder to read at 20 mm. Shorten the link rather than shrinking the code.

Produce the whole range in one pass from your product spreadsheet — one row per line, the product name as the code name so the report is readable — and keep them in a folder per department.

Loyalty at the till, review on the receipt

The till is the one place in the shop where the customer is standing still, waiting, phone usually already in hand. That is where a loyalty signup code belongs — not on a poster at the entrance where nobody stops. Keep the signup form to an email or a phone number; anything longer is abandoned in the queue.

The review code works better on the receipt or a small card in the bag than on the wall: the customer reads it at home, when the purchase has landed well. Link it to the direct review form rather than your business profile, and never filter people by rating before sending them to Google — that breaks Google's policy and can cost you the profile.

Print widths that scan at shelf distance

Two shop-specific traps. Glossy shelf strips and glass shelves reflect the ceiling spotlights straight into the camera — print matte. And a window code is scanned through glass at an angle, often with a reflection of the street across it: go one size up from the calculated minimum, and place it at chest height rather than at the top of the window.

What the scan report tells you about the shop floor

Dynamic codes count scans by day and hour, so after a month the report answers merchandising questions directly: which product lines people want to know more about, whether the window earns anything after closing, whether the fitting room code is used enough to justify staffing it differently. Retire the codes nobody scans and move the ones that work to eye level. Reports count scans; they do not identify customers.
