Tap to connectNever lose a contact again.
Smart event tags that turn every handshake into a clean contact – without apps, QR scans, or manual follow‑ups.
The real story
A touch away from real connections.
You meet someone great.
You say you’ll stay in touch.
Then one of these happens:
You forget their name
Their business card disappears
You never send the follow-up
The connection is lost
Not because it didn’t matter.
Because the process is broken.
The solution
Contag makes it work.
Just touch.
Your contact details transfer instantly.
Name, role, company, links — cleanly saved.
What used to take minutes now takes one second.
Tap to connect
How it works
Three seconds. One touch.
No apps to download. No QR codes to scan. Just a simple, human interaction.
Wear your Contag
Your tag holds your full digital identity — name, role, company, socials, phone, website. All encoded in a single NFC chip.
No batteries. No charging. It just works.
Touch tags
Meet someone? Just touch your tags together. No phones, no apps, no fumbling — the connection happens instantly.
The most natural way to exchange info. Takes less than a second.
Instantly connected
Your full contact card opens on their screen. They save it instantly. Your info goes straight into their phone — not a pocket, not a drawer.
No typos. No lost cards. No “I'll add you later.”
That's it.
Every connection saved. Every follow-up possible.

Why Contag
The details that make it work.
10x more follow-ups
When capturing a contact takes one tap instead of five minutes, people actually do it.
Zero app installs
Contag works with the phone's native NFC reader. Nothing to download, nothing to explain.
Works offline
No Wi-Fi? No problem. Badge taps are stored locally and sync when connectivity returns.
Privacy-first
Attendees control what they share. No background tracking, no data harvesting, no surprises.
5-minute setup
Upload your attendee list. We ship pre-programmed badges. That's it.
Sustainable
Made from recycled PET. No batteries, no electronics waste. Collect and reuse across events.
Why it works
People don't forget the tap.
Capturing a contact takes one tap instead of five minutes of typing — so people actually do it, mid-conversation, without breaking stride.
No app to open, no QR code to scan. The exchange happens the moment two badges tap, and it's already in your phone.
Upload the attendee list, badges arrive pre-programmed. Nothing for organizers to configure on-site.
Your next event deserves better connections.
Whether you're running a 200-person meetup or a 10,000-seat conference, Contag scales with you. Get in touch to run a pilot.
