Everyone has done the awkward dance: shouting your email over music, watching someone fat-finger your number, spelling your last name twice. It is slow, it is error-prone, and half the time the details end up wrong or never saved at all.
A QR code ends it. One scan and your name, number, email, and links land in their phone — correct, complete, and ready to save as a contact.
Where to keep your QR ready
The whole point is speed, so your code should be somewhere you can show it instantly, without opening an app or searching your files.
- As your phone's lock-screen or wallpaper for an instant flash.
- Printed small on the back of a physical card, if you still carry one.
- Saved as a photo you can pull up in one swipe.
Make sure it saves cleanly
The best contact QR does not just show a page — it lets the other person add you to their address book in one tap, with your details already filled in. That is the difference between a link they forget and a contact they keep.
Send it to a card, not a raw text blob, so they also get your links and a way to reach you beyond a phone number. You can create a contact QR free at onesol.io/card that opens your card and lets anyone save you in a single tap.
Make It Reachable in One Gesture
The two seconds only happen if the code is already on screen when you need it. Dig through three apps to find it and the moment has gone. Save your contact QR as an image in your phone's wallet, or set it as your lock-screen wallpaper, so it appears the instant you wake the phone — no unlocking, no searching, no fumbling.
A tidy option is to add it to Apple Wallet or Google Wallet as a pass, which puts it a double-click of the side button away. Whichever route you pick, rehearse it once: from phone-in-pocket to code-on-screen should be a single, boring movement you never have to think about mid-conversation.
Picture the moment at a networking event when someone asks for your number. Instead of "let me find you on LinkedIn", you double-click, turn the screen, they scan, and your full details — name, mobile, email, website — land in their contacts at once. You've shared more, and more accurately, in less time than it takes to spell your surname aloud.
Put the Right Fields on It
A contact QR carries a vCard, and a vCard holds far more than a phone number. Include your mobile, the email you actually read, your website or digital card, and a job title so that future-you shows up correctly in the other person's phone. Leave off anything you'd hesitate to hand a complete stranger across a table.
Think about how you'll look in someone else's address book six months from now. "Sam — mobile" is useless when they're scrolling past a hundred other Sams; "Sam Reed, Reed Joinery, Bristol" is instantly findable. The company and role fields aren't padding — they're the very thing that makes you searchable long after the handshake.
Keep one personal version and, if you need it, one work version. Handing a client the work card with your booking link, and a friend the version with your personal mobile, is a small courtesy that a single printed card can never manage. The code costs nothing to duplicate, so tailor it to who's standing in front of you.
Update Once, Not Everywhere
The advantage over a printed card is that a hosted contact code can point at details you're free to change. Switch numbers, move house, or take a new role, and you update the destination once — every code you've ever shown now delivers the current details, with nothing reprinted and no awkward "ignore the old number" texts to send round.
Mind one edge case, though. A code that loads a hosted page needs signal to open it, so in a basement venue or on a plane it may stall. If you regularly share contacts in dead-signal spots, use a code that encodes the vCard directly rather than linking to a page; it saves the contact with no connection at all, at the cost of not being editable later. Pick the trade-off that fits where you actually meet people.
Whichever you use, check it after any change. Scan your own code with a second phone and confirm the saved contact is complete and correctly spelled. An out-of-date or half-filled card shared confidently is worse than no card at all, because the other person trusts what they just saved and won't think to question it.
