QR codes for a market stall

Payment first — pick your region's scheme

The stall use-case that pays for itself immediately is taking payment without card hardware. Which QR to print depends entirely on where you trade:

Region	Scheme	Generator
India	UPI — universal, instant, no merchant fees at typical stall scale	UPI code; the small-shop guide covers setup
Brazil	PIX — instant, near-universal	PIX code; details in PIX for small business
Singapore	PayNow — see the PayNow guide	Bank app export
SEPA / EU	EPC QR initiates a credit transfer in banking apps — useful, though not tap-speed like the schemes above	EPC format
UK / US	No universal bank-QR scheme — a payment-link QR (PayPal, or your processor's link) is the honest fallback, fees included	PayPal code

Generate the code on this side of the browser — UseQR builds payment payloads client-side, so your VPA or key never leaves your device — print it large (≥ 5 cm for a code scanned across a stall table), and tape a copy at eye level and one flat on the table. A static amount-less code lets the customer type the total; the trade-offs are on static vs dynamic UPI, and the scam patterns worth knowing (code swapped overnight, fake "payment failed" screens) on UPI security.

The same-phone caveat

The classic stall mistake: showing a payment or menu code on your own phone to a customer — who then cannot scan it, because their camera is in their pocket and yours is displaying the code. It works, but only when the customer's phone does the scanning of your screen, with your brightness up. It fails completely when a customer tries to open your catalogue on the same phone that displays the code — the same-phone problem in the wild. Paper beats screens at a stall: no battery, no brightness, no queue for your phone.

The price-list-with-codes sheet

The second sheet that earns its lamination: your price list with a small code per product line — each linking that product's page for ingredients, care, or ordering the size you did not haul to the market. One A4 sheet, codes at ≥ 2 cm (customers hold the sheet), generated together with the bulk tool. It turns browsing time in a queue into catalogue time, and the Etsy-seller kit — care cards, thank-you cards — carries the same buyers home.

Third sheet: one follow code — mailing list over social, as with pop-ups, because the stall's location changes and your list is how regulars find you.

Weatherproofing, briefly

A market stall is outdoor print on a budget:

• Matt lamination — gloss pouches glare in direct sun exactly when markets happen; the physics is on glossy surfaces.
• Laminated sheets survive rain and wipe clean; unlaminated inkjet dies in one shower. For codes stuck to crates and boards, weatherproof stickers are the durable option.
• Wind is the real enemy — clip or weight every sheet; a payment code face-down on the ground takes your card-free revenue with it.
• Test-scan at the stall in morning light and afternoon glare, not just at home.

FAQ

Which payment QR code should a market stall use?

Your region's bank-transfer scheme: UPI in India, PIX in Brazil, PayNow in Singapore, an EPC transfer code in the SEPA area. In the UK and US there is no universal scheme, so a payment-link QR from PayPal or your processor is the fallback.

Why shouldn't I show my payment QR on my phone?

A screen code only works when the customer scans your phone — it fails in sun glare, dies with your battery, and queues customers behind one device. A laminated printed code at eye level works all day for everyone at once.

How do I make my stall signs survive the weather?

Matt lamination on every sheet, weatherproof stickers on crates and boards, and weights or clips against wind. Gloss lamination glares in sunlight, which is when markets operate, so choose matt.

What size should a stall payment QR be?

At least 5 cm across for a code scanned over a stall table at about half a metre, following the ten-to-one distance rule. Put one at eye level and one flat by the till point.
