QR Code on a business card: what to include and what to avoid

The business card is still alive because it solves a social problem: continuing a conversation. A QR Code improves it by removing typing — but only when the choice of type and size is made with judgement. Poor execution produces a handsome card with a code nobody can scan.

Choose the type by what you want to happen

The right question is not "which QR Code should I use", it is "what do I want the person to do after scanning".

• Want them to save your contact? Contact QR Code (vCard). One tap and you are in their address book.
• Want them to see your work? Link QR Code pointing at your portfolio, site or LinkedIn.
• Want them to message you now? WhatsApp QR Code, with a ready message identifying where the contact came from.
• Want them to call? Phone QR Code.

One card, one goal, one code. Two codes side by side split attention and reduce the chance either gets used.

The vCard paradox

The vCard looks like the obvious choice and is exactly where most people come unstuck. The reason is technical: it carries a lot of text, and more text means more modules in the same space.

A vCard with full name, two phones, two emails, company, job title, address and website produces an extremely dense code. Printed at 2 cm in the corner of a card, with high error correction because you also wanted a logo, it simply will not scan in normal conditions.

If you do use a vCard, be economical:

• Name, one phone, one email and the company. That is it.
• Leave the full postal address out unless it is essential.
• Do not add a logo as well — pick one or the other.
• Reserve at least 2.5 to 3 cm per side in the layout.

If you genuinely need a lot of data, the elegant alternative is a link QR Code pointing at a contact page of yours. Less dense, updatable, and you also find out how many people visited.

Size and position on the card

• At least 2 cm per side, and 2.5 to 3 cm if the content is a vCard. Below 2 cm scanning is unstable for any type.
• Respect the white margin. The 4-module clear zone has to fit. A code touching the card edge or the text is a guaranteed failure.
• The back is better than the front. On the back it can be larger and does not compete with name and job title.
• Matte finish over the code area. Gloss varnish and lamination reflect and interfere, and business cards are exactly where people invest in finishing.

Say what the code does

A short line beside it greatly increases usage, because it removes the hesitation of scanning without knowing what comes next:

• "Scan to save my contact"
• "See the portfolio"
• "Message me on WhatsApp"

Never replace the text with the code

The QR Code is a shortcut, not a substitute. Keep name, phone and email printed in readable text on the card.

Practical reasons: not everyone scans on the spot, many people keep the card for later, phones run out of battery, and some prefer to type. A card with nothing but a black square in the middle is useless to those people — and there are plenty of them.

Test before the print run

Ask for a printed proof before committing to a thousand units. Scan with an iPhone and an Android, in ordinary indoor light, holding the card the way people hold it — slightly tilted, about 25 cm away.

If you have to move closer, insist or adjust the angle, enlarge the code or cut the content. Full details in the print size guide.
