QR code on business cards and foil

A QR code on business cards competes with type, foil, and round corners on an 85 by 55 mm ticket. Keep the symbol above 2 cm and the quiet zone inside the card edge, not bled off a rounded corner. Print modules in flat ink, not in foil. Send SVG, not a preview screenshot.

QR code on business cards without eating the type

You are about to fit a scannable grid onto a card that already has a name, a title, and a designer who wants 12 mm of footer. This is the wrong job for a chest print (apparel) and the wrong job for a carton (packaging). A single networking event with a static personal URL you will not count is a Canva job.

Retail marketing teams reprint cards when people leave. A website or dynamic code on the card lets the landing page follow the next hire. A vCard landing page can still be edited if it is hosted; a static vCard in the modules cannot.

Conference badges in a plastic holder add glare and a second layer. If the card will live in a badge, test through the holder. Soft-touch laminate feels expensive and often lowers contrast. Ask for a matte test card, not merely the soft-touch drawdown.

Edge painting and coloured stocks that bleed into the face can stain the quiet zone. Keep a paper-coloured margin. Thermography (raised resin) on the name is fine; thermography on the modules is letterpress's cousin and will fail.

Fit the symbol inside the card, not off the round corner

1. Measure the remaining flat rectangle after type and logos. If it cannot hold 2 cm plus a four-module quiet zone, drop something else, not the millimetres.
2. Keep the round corner quiet zone inside the radius. Die-cut rounds that clip a finder are a classic fail.
3. Export SVG for offset, foil blocking, and letterpress shops. Digital toner can take 300 dpi at the placed size.
4. On a foil business card, ink the QR on an unfoiled white or light patch. Foil around, never through, the modules.
5. Skip letterpress texture on the symbol. Keep QR on a flat inked area. Deboss the name, not the grid.
6. If you insist on a logo in the centre, grow past 2 cm. Wallet wear is already damage.
7. Print a card, sit on it in a pocket for a day, and scan. Then run the box.

The preview encodes /qr-preview. Download the real file. Transparent files on dark stocks still need a light patch.

How small can a card qr go

The working floor is still about 2 cm at 30 cm. Cards are scanned at handshake distance, so the floor applies. Going to 12 mm to save the address block is how you collect compliments and zero contacts. Cropping the quiet zone to hug the 85 mm card edge is the other way to lose.

Thick plastic cards with a deep reveal can shadow modules. Keep the grid on the raised face, not in a well.

Can foil or letterpress carry modules

Metallic grounds scatter. Texture breaks edges. Both are documented failure modes. A beautiful black foil QR on black board is an invert-plus-scatter pileup. Light patch, then decoration around it.

Spot-colour offset should still treat dark modules as 100 percent of one ink.

Card codes that fail in a wallet

Crease through a finder. Rub on a metallic ink. A hosted page that still lists last year's company. A static vCard with an old mobile number. A screenshot file that went grey on a digital press.

vCard is parsed by the contacts app, not by a browser. The user still confirms save. That is OS behaviour, not a card-stock setting.

How to handle double-sided cards and magnetic backs

If both faces carry a code, you have a two-tents problem in a wallet. One face, one symbol, unless the two payloads are meant to be chosen on purpose and are captioned. Magnetic backs on fridge cards pick up grit that fills light modules. Wipe them like a window, or keep the grid on the non-magnetic face.

Plastic cards with a chip well or a deep reveal shadow the grid. Keep QR on the raised face. Rounded corners on plastic are still a quiet-zone problem: the radius eats modules the same way a paper die does.

Dark boards with white ink need the inverse contrast to stay legal: dark modules, light ground. White modules on black board without a true invert fail. A white patch with black modules is the boring file that scans at a conference bar.

A stack of cards in a bowl at a trade stand is scanned at arm length in bad hall lighting. The 2 cm floor still holds. Fancy 8 mm marks in the corner do not.

Spot UV on the rest of the card is fine. Spot UV on the modules is gloss glare in a 2 cm patch. Keep the grid unvarnished or matte-varnished. Foil stamping next to the quiet zone is still foil scatter if a flake lands in an alley.

When typing the URL is faster than a code

If the card is a one-run student project with a URL the person can say in one breath, skip the grid. If you need a code and it will never be edited or counted, use a free static generator. SmartQRCode has no unpaid plan. Use $97 when the same plate should outlive a job title.

Scan the sat-on card. The draw-down proof is not a wallet. If you mail cards in a window envelope, the window film is another layer of gloss. Test through the envelope if that is how they arrive. Name-badge clips that cover a corner finder will fail the same way a round die does. Keep the grid away from the clip corner, even if that means dropping a second job title line. Cards that live in a phone case against a wireless charger pick up a curve; scan the bowed card, not the flat proof.
