QR codes on business cards
Should you put a QR code on a business card?
Put a QR code on a business card only if it saves the recipient work — opening a portfolio, saving your number, booking a call. If it points at a homepage they could have typed, it earns nothing and costs design space. Roughly a third of people searching this question are asking whether to bother, and for a plain contact card the honest answer is often no.
The reputation problem is specific and fixable. What people picture is a code with no label taking up a quarter of the back of the card, pointing at a company homepage — which is the version that was printed by the million a few years ago and taught everyone that the feature is filler. A 1.5 cm code in a lower corner with three words under it is a different object.
Worth it
- Anything visual. A portfolio, a showreel, a menu, a property listing — things a card physically cannot hold.
- Booking. Straight into a calendar link is the highest-converting thing a card can do.
- Saving your details without typing, if it goes to a contact page rather than a raw vCard payload.
- Cards you hand out in volume at events, where knowing which event produced scans is worth something.
Not worth it
- A homepage anyone could type from the card itself.
- A social profile you already printed the handle for.
- A card for people who will never scan it — know the room.
The size that actually works at card scale
A business card QR code should be 0.6–0.8 in / 1.5–2 cm square. A card is read from about six inches, and the 10:1 ratio puts the floor at 0.6 in. Below roughly 2 cm on uncoated or textured stock, ink spread begins merging modules regardless of the arithmetic, so treat 2 cm as the working minimum for anything that is not gloss.
Two things buy you margin at this size, and both matter more here than anywhere else because there is so little of it. Keep the payload short — the fewer characters encoded, the fewer modules across the same width, and the bigger each module prints. Andkeep the quiet zone, four modules of blank space on all sides, which on a card is about 2 mm and looks like a lot until you understand that cropping it stops the code being findable at all. Check the width against the distance if you are unsure.
vCard or link? The one that ages badly
A vCard QR encodes your entire contact record — name, title, phone, email, company, address — into the pattern itself. It works offline, which is the argument for it, and it has two problems that show up later.
It is dense. All that text becomes modules, and at 1.5 cm those modules get very small. A vCard code is one of the hardest things to scan reliably at business-card size, which is exactly the size it is always printed at.
It is frozen. Change your number, your title or your company and every card in circulation is wrong, permanently. A short link to a contact page has neither problem: the pattern stays coarse because the URL is short, and the details stay editable because they live on a page rather than in ink. It is also the only version that can tell you whether anybody scanned.
Designing it so it does not look like filler
- Back of the card, lower corner. The front is your name.
- Label it in three words. “Scan for portfolio.” “Scan to book.” “Save my details.”
- Give it real clear space. Nothing inside the quiet zone. No rules, no text, no edge of a photo.
- Match your ink, keep the contrast. A dark brand colour on white is fine; mid-grey on cream is not. Hold at least 3:1.
- Never invert it. Light modules on a dark card fail on plenty of older scanners even when contrast looks fine.
- A logo is optional and expensive here. At 1.5 cm a centred logo eats margin you do not have. If you must, use error correction level H and keep it to about 20% of the width.
- Print a proof and scan it before the run of 500. On the actual stock, in ordinary indoor light.
The stock decides more than the design does
Matte and uncoated cards absorb ink and spread it — the reason for the 2 cm floor. Soft-touch laminate is worse than it looks, because the finish scatters light. Gloss is technically the easiest to scan and the most likely to throw a reflection back at the lens under a ceiling light. Letterpress and foil are the two to be careful with: a debossed or foiled code has physical depth that casts its own shadows, and foil is reflective enough to defeat autofocus entirely. If the card is a premium finish, print the code larger and test it on the real stock, not on a proof from a different printer.
Questions
The things people ask before they commit something to paper.
What size QR code fits on a business card?
Between 0.6 in / 1.5 cm and 0.8 in / 2 cm. A card is read at about 6 inches, so the 10:1 ratio gives 0.6 in as the floor — but ink spread on uncoated stock starts merging modules below roughly 2 cm, so size up rather than down if the card is matte or textured.
Should a business card QR code be a vCard or a link?
A link, in almost every case. A vCard payload encodes the whole contact record into the pattern, which makes it dense and hard to scan at card size, and it freezes your details in ink the day you print. A short link to a contact page stays coarse, stays editable, and can tell you whether anyone scans it.
Is a QR code on a business card unprofessional?
It reads as dated only when it is unlabelled and points at a homepage — which is the version most people have seen. A small, labelled code that saves someone typing, on a card that is otherwise well designed, reads as considerate. The design crime is the code, not the concept.
Where should the QR code go on a business card?
On the back, lower corner, with real clear space around it. The front is for your name. Putting the code on the back also means the quiet zone is easy to protect, because there is nothing else competing for the space.
Can I track scans from a business card?
Yes, if the code points at a short link rather than encoding your details directly. You will see how many scans, roughly where and on what device — never who. Given the volumes involved, the useful signal is usually which event or which card batch produced anything at all.
