How do I share my contact info without a business card?

Use a digital business card with a QR code. Open it on your phone, let the other person scan it with their camera, and your contact details transfer instantly. No app needed on either side.

What is the best way to exchange contacts at a conference?

Use a real-time contact exchange platform like Yoyo. Both people scan one QR code and see each other's details appear live. Both walk away with the contact saved — no typing required.

Can I share my business card without an app?

Yes. Browser-based digital cards like Yoyo work entirely in the phone's web browser. Neither you nor your contact needs to download anything. Just open a link or scan a QR code.

How to Share Your Contact Info at Networking Events (Without Paper Cards)

Why Paper Cards Fail at Networking Events

88% of paper business cards are thrown away within one week of being received. At a busy conference, paper cards pile up in pockets and bags, making it nearly impossible to remember who gave you which card. By the time you get home, the connection is cold.

Digital sharing solves this by delivering contact details directly to both phones — where they're searchable, saveable, and won't end up in a recycling bin.

7 Ways to Share Contacts Digitally at Events

There are more options than ever for sharing your details without paper. Here are the seven most practical methods, ranked by convenience.

QR code on your phone screen — The universal method. Show your QR code and let the other person scan it with their camera. Works on every smartphone.
Real-time contact exchange — Both people scan one QR code and see each other's details appear live. Platforms like Yoyo make this seamless.
Proximity sharing (bump-to-share) — Touch phones together and exchange cards using ultrasonic audio and GPS proximity. No NFC chip needed.
Shareable link via text or AirDrop — Send your card link directly via iMessage, WhatsApp, or AirDrop.
QR code on physical materials — Print your QR code on a lanyard badge, sticker, or even a paper card as a bridge to your digital profile.
NFC tap — If you have an NFC-enabled card or phone, tap to share. Limited to compatible devices.
Email signature link — Include your digital card link in your email signature for post-event follow-ups.

QR Code Sharing: The Universal Method

QR codes work on every modern smartphone without any app installation. iPhones (iOS 11+) and Android phones scan QR codes directly from the camera app. This makes QR the most reliable method at events — you don't need to ask "do you have the app?"

To share via QR at an event: open your digital business card, display the QR code, and let the other person point their camera at it. The card opens instantly in their browser.

Real-Time Contact Exchange: How Two-Way Sharing Works

The biggest limitation of traditional sharing is that it's one-way. You give your card, but you don't get theirs. Real-time contact exchange platforms like Yoyo solve this by creating a live session where both people enter their details and see each other's information appear on screen simultaneously.

This means both of you walk away with the contact saved — no "I'll send you my details" promises that never happen.

What to Do After the Event: Follow-Up Best Practices

The connection you make at the event is only as valuable as your follow-up. Digital contact exchange gives you a major advantage: you already have their details saved.

Follow up within 24 hours — Send a brief message referencing your conversation while it's fresh
Connect on LinkedIn — Mention where you met in the connection request
Add context to the contact — Note where you met and what you discussed
Share something relevant — An article, introduction, or resource related to your conversation adds immediate value
