How a business card QR code works
A business card code made here holds a vCard 3.0 contact card, the format phone address books read. When someone scans it, the phone shows your name, company, number and email in a contact preview, and one tap adds it. Nothing has to load, so it works in a conference hall with poor reception, and your name is saved exactly as you spell it.
The alternative is a code that links to a profile, such as your website or LinkedIn page. A link can show more and its page can be updated without reprinting, but the person still has to save your number themselves. A contact code does the saving for them. Some people use both: the contact code on the back, and a short website address printed as text.
Every field you fill in is stored in the image, so the code grows with the information. A card with name, company, mobile, email and website stays compact; adding a full street address and a note makes the pattern denser and harder to read at business card size.
Where it helps
- Networking events and trade fairs, where you hand out dozens of cards and want each one to end up in a phone rather than a drawer.
- Freelancers and consultants who meet clients in person and want the right email and number saved, not guessed from a photo of the card.
- A sales team's cards, where each person gets a code with their own direct line.
- A reception card that saves the general office contact for visitors.
Tips before you print
- On a standard 85 × 55 mm (3.5 × 2 in) card, print the code at least 2 cm (0.8 in) wide, with a clear margin around it. If it has the back to itself, 2.5 to 3 cm is more comfortable.
- Keep to the fields people need: name, company, mobile, email and website. Leave the address and note empty unless they matter.
- Write numbers with the country code, such as +1 415 555 2671, so they work for contacts abroad.
- The Batch page makes link and text codes, not contact cards. For a team, make each person's code on this page and save the SVG file for each card design.
- Scan a printed proof with an iPhone and an Android phone and check that name, number and email land in the right fields.
