How does a QR business card work?

The QR code holds your contact details in the standard vCard format. When someone scans it with their phone camera, the phone offers to save you as a new contact — no app needed on iPhone or most Android phones.

Can I update the details after printing?

Not with this static code — the details are inside the QR itself, so changing them means a new code. If you expect changes, point the QR at your personal website or digital visiting card instead, which you can edit any time without reprinting.

What size should I print it?

At least 2 × 2 cm on a business card, with a white margin around it. Test-scan the printed proof from arm’s length on two different phones before ordering a full batch.

Is my information stored?

No. The code is generated on the fly from what you type and nothing is saved.

Static QR vs. a digital visiting card

This free QR stores your details inside the code itself, which is perfect for a quick contact save. The limitation: once printed, it can’t change. A digital visiting card puts a QR on your card that opens a page you can update any time — new number, new job, new portfolio — plus buttons for WhatsApp, email and directions.

Tips for a QR people actually scan

Add a short call to action next to it, such as “Scan to save my number”.
Keep dark code on a light background — inverted or low-contrast codes fail on many phones.
Fewer fields make a simpler code that scans faster from further away.

What goes in

Name: first and last name, job title: Interior Designer Mobile, work email, website and city Print size: 2.5 × 2.5 cm on the back of a card

What you get

The tool stores the details as a vCard, so when a client points a phone camera at the code, the phone offers to save a new contact with the name, title, number, email and website filled in. At 2.5 cm with a white margin around it, the code scans reliably from a printed card. The designer test-scans the print proof on two different phones before ordering the batch. Because the code is static, a new number later means a new code and new cards, so she keeps a website link on the card as well.

Common mistakes

Printing the code too small or without a white margin, so phone cameras struggle to read it, especially in dim light.

Ordering a full print run without test-scanning the proof on two different phones first, which is the only way to catch a typo in the contact.

Putting a number you plan to change soon into a static code, which then has to be reprinted on every card.

When to use it: Use the contact QR when people should save your details by scanning; to share a full profile with projects and links, a personal website link works better.
