How to make a QR business card

A QR code on a business card is easy to make and easy to get wrong. The code itself takes ten seconds to generate. Making one that actually gets scanned, and actually turns into a conversation, takes a bit more thought about what it links to and where you put it.

Step 1: Build the thing it links to

The most common mistake is generating a QR code before deciding what it should open. A QR that links to a plain PDF resume or a static “save my contact” vCard is fine, but it wastes the moment — someone curious enough to scan a code is curious enough to see more than a phone number. Build a full profile first: photo, title, the links that matter (booking page, portfolio, listing, socials), and — if you want to actually capture the person scanning, not just inform them — a short lead form. mcard generates the QR automatically once the card exists, so this is really the only step that takes real effort.

Step 2: Make the code itself scan reliably

A few things break QR codes more often than people expect:

• Low contrast. Dark modules on a light background scan fastest. A code printed in a light brand color on cream card stock might look nice and fail half the time.
• Size below about 2cm (roughly three-quarters of an inch) square at normal reading distance. Smaller than that, phone cameras start hunting for focus.
• A logo dropped in the middlethat covers too much of the code. A small logo in the center is usually fine — QR codes have built-in error correction — but a large one can break the scan entirely.
• No quiet zone. Leave a clear margin of blank space around the code; text or borders crowding right up to the edge confuse the scanner.

Test it yourself before you print anything — scan the actual printed proof, not a code on a screen, since paper stock and print quality both affect contrast.

Step 3: Put it where people already are

The code only works if it's somewhere a phone camera is already pointed. That's different for every profession, but the pattern is the same: put it at the exact moment someone is deciding whether to remember you.

• The physical card— a corner, not the whole face, so the rest of the card still reads normally.
• A yard sign rider or listing flyer, for real estate — see mcard for realtors for the full setup.
• A booth or badge at a trade show — our guide for sales reps covers running a kiosk view that turns any screen into a scan-to-save station.
• An email signature, next to your name, not buried below a legal disclaimer no one reads.
• A name badge or lanyard at a conference, so a conversation ends with a scan instead of a scramble for paper.

Step 4: Know whether it worked

The last step is the one a plain QR generator can't give you: what happened after the scan. A code that just opens a link is a black box — you'll never know if three people scanned it or three hundred. A card built on mcard tracks views, taps, and rough geography per share, so a QR on a conference badge and a QR on your email signature can be compared honestly instead of guessed at.

The five-minute version

If you want the short path: build your card, add the two or three things that matter most for your work, and the QR is generated for you — no separate generator, no dead link to maintain, and no code you forgot points at your old job title.
