PosterBell

The doorbell for your conference poster

Be at your poster without standing next to it.

Your poster hangs there all conference long, but you can only stand next to it during the session. PosterBell adds a small QR code: visitors ring you, your phone buzzes, and you answer with one tap — “On my way.” Go see the other posters. You won’t miss the conversations at yours.

  • Set up in 2 minutes
  • Visitors need no app
  • Works with posters already printed
A visitor scans the QR code next to a poster; the author, elsewhere at the conference, gets the ring on their phone. PosterBell · now Someone is at your poster On my way 5 min 15 min Leave a message You: Session 4B · Hall C, 200 m away

The poster session dilemma

You can’t be in two places at once. But you can be one tap away.

Stay at your poster, and you miss the posters closest to your own work. Walk around, and you miss the person who came to talk to you — they leave, and you never find out who it was. With PosterBell you do both: when someone is at your poster, you know within seconds, and they know you’re coming.

How it works

Two minutes to set up — even at the conference.

Plan ahead and build the QR code into your poster, or add it on the day with a printed sign. Either way, your poster is reachable from the moment it hangs.

  1. Step 1

    Add your poster

    Title, and the PDF if you like. Get alerts by e-mail, or connect Telegram for one-tap replies. No password needed.

  2. Step 2

    Add the QR code

    Before printing: drop it into your poster design, in your colours. Already hanging? Print the sign and pin it next to your poster.

  3. Step 3

    Answer from anywhere

    When someone rings, your phone buzzes. Tap “On my way” or “15 min” — or ask them to leave a message. The visitor sees your reply instantly.

What you get

More than a doorbell.

Every scan is a chance for a conversation — or a contact you’d otherwise never have heard from.

Instant alerts

Telegram or e-mail, with “On my way”, “5 min”, “15 min” and “Leave a message” as one-tap replies.

Messages, not missed chances

If you can’t come, visitors leave a question and their contact. It lands in your inbox.

Your PDF, on every phone

No more stacks of A4 handouts, no more “can you e-mail me the poster?”

A QR that fits your design

Three styles, your colours, transparent background, PNG or SVG — plus the printable sign.

“After eight years of conferences, I knew the feeling from both sides: standing by my own poster while the ones I wanted to see were across the hall — and walking up to a poster I cared about, with nobody there to talk to.”
— Stefan, researcher and founder of PosterBell. Built by researchers, for researchers.

For conference organizers

Let’s run a conference pilot.

Try PosterBell with a small group of presenters at your next poster session. We’d like to learn what helps visitors and authors connect.

Questions

Do my visitors need an app or an account?

No. They scan the QR code with their phone camera and get a small web page: ring you, download your PDF, or leave a message. Nothing to install, nothing to sign up for.

What if I can’t answer right away?

The visitor sees the ring status while waiting for your reply. If you don’t reply within a few minutes, the page offers them the message form instead — so they can leave their question and contact details.

Do I need Telegram?

No — e-mail works on its own. Telegram is the fastest option: the alert pops up on your lock screen with one-tap reply buttons.

My poster is already printed. Can I still use it?

Yes. Print the A5 sign PosterBell makes for you and pin it next to your poster. For your next poster, you can put the QR code straight into the design — PNG or SVG, in your poster’s colours.

Does it work on crowded conference Wi-Fi?

Yes. The visitor page is a few kilobytes — no frameworks, no trackers — and it keeps working on slow mobile data and roaming.

What does it cost?

Nothing, while PosterBell is in beta. We are exploring optional paid features, but have not set their pricing or details.

What happens to my visitors’ data?

Messages are stored so authors can read and answer them. After 90 days, authors choose whether to retain existing messages. See our privacy notice for details. No analytics services, no ads, no tracking of visitors.
