How to Share Your Contact Info with a QR Code

You meet someone at a conference. Instead of fumbling for a paper card or spelling out your email, you show them a QR code. They scan it, tap save, and your contact info is in their phone. Done in five seconds.

Here's how to set that up.

How QR code contact sharing works

A QR code business card links to a digital card with your contact details. When someone scans it, they see your info and can download a .vcf file—the standard format that saves directly to phone contacts on both iPhone and Android.

No app required. The phone's built-in camera handles everything.

What to include on your card

Keep it focused on what people actually need:

Essential: Name, phone number, email, job title, company

Optional: LinkedIn, website, office address, headshot

Skip: Fax numbers, multiple emails, anything you don't check regularly

The goal is making it easy to reach you, not listing everything about you.

Where to use your QR code

Once you've created your digital business card, you'll get a QR code you can use anywhere:

Email signature. Small QR code image at the bottom. People can scan right from their screen.

Phone lock screen. Set your QR code as your wallpaper for instant access at events.

Printed materials. Add it to paper cards, brochures, name badges, or booth displays.

LinkedIn banner. Put it in your cover photo so profile visitors can grab your contact fast.

Presentations. Last slide with your QR code—audience scans before they leave.

Tips for better scans

QR codes are reliable, but a few things help:

Size matters. For print, keep it at least 1 inch square. Smaller codes are harder to scan from a distance.

Contrast is key. Dark code on light background works best. Avoid putting QR codes on busy images.

Test it. Scan your own code with a few different phones before printing 500 copies.

The permanent link advantage

Here's the best part: your QR code points to a URL that stays the same forever. Change your phone number? Update your card online—the QR code still works. Everyone who ever scanned it can now reach you at your new number.

With paper cards, you'd be reprinting. With a virtual business card, you just edit and save.
