The fastest way to design a good code is to see what the job looks like done well. Each example below links the tool that makes it — styled, free, in a minute.
What it looks like: a 2cm code on the back, brand-coloured with a small logo, next to "Scan to save my details". Why it works: a vCard code carries the contact data inside it — one scan saves everything, even offline. Keep the data lean so the code stays sparse at card size.
What it looks like: a 3–4cm code under "Menu", dark on cream to match the brand. The pro detail: it is an editable code, so Tuesday's price change never means Wednesday's reprint. (Menu codes guide.)
What it looks like: a framed A5 print by the door — "Scan to join our WiFi" over a WiFi code. No password spelling, no router-sticker hunting. The single most thanked code in hospitality.
What it looks like: a credit-card-size handout with the till receipt: "Enjoyed it? Scan to leave a review" over a Google review code. Captures the customer at peak happiness.
What it looks like: a PayPal or Bitcoin code on a market-stall stand with the price list. Fixed-amount links pre-fill the payment.
Codes that fail, and why: the pale-gold-on-white wedding code (contrast), the code wrapped around a mug (geometry), the billboard code 20 metres up (size ÷ 10 rule), the trimmed-border flyer (quiet zone), and the trial-platform code that died after 14 days (expiry). The full diagnosis list: not scanning?
Every example above is reproducible in the free generator — type, style, logo, download. The design rules that keep styled codes scannable are in custom QR codes.
A square grid of dark modules on a light background with three large corner squares. Beyond that, colours, rounded patterns and centre logos are all fair game — the examples above show the range.
Menus, guest WiFi, business cards, review requests, payments, event tickets, parcel tracking — anywhere typing a link is friction.
