The QR Code on a Scientific Poster: Why and How

Quick answer: do you need a QR code on your poster?

Yes, it has become a useful standard. Nobody leaves with your poster under their arm: a QR code lets a visitor keep a link to your work (full paper, data, or a web page mirroring the poster) and reach you after the conference. It is a "take-away" element, recommended by university presentation guides.

Why a QR code extends the exchange

A poster session lasts a few hours; your work deserves to travel further. The University of Toronto library specifically recommends providing a take-away (a link, a summary or a QR code) so visitors can refer to it later. The QR turns a ten-second interest into a lasting link, without printing handshakes or handing out dozens of pages.

What to point the QR code to

The destination matters as much as the QR itself. Useful targets:

• The full paper (or its DOI), for anyone who wants the scientific detail.
• The data or supplementary material (repository, table, code).
• A web page mirroring the poster, ideal when the paper is not yet published: the visitor finds your message and contact details online.

One well-chosen QR beats three QRs competing for attention. Decide on the main action you want to trigger.

How to make it scannable and reliable

A poorly made QR will not scan. A few simple rules:

• Big enough: visible and scannable at arm's length, not a postage stamp.
• Strong contrast: dark on a light background, no image behind it.
• A clear label: "Paper and data," "Read the paper"... the visitor should know where they are going before scanning.
• Test it before printing, with several phones.
• Check the destination: a dead link on a printed poster cannot be fixed anymore.

Colin Purrington, in his reference guide on posters, lists the QR among the good reflexes, provided it leads to genuinely useful content.

The companion page: the best QR target

Pointing the QR to a web page dedicated to your poster is often the best option: it mirrors your content, stays accessible long after the conference, and centralizes your contact details and links. That is exactly what Folio Poster offers: each poster can expose a shareable companion page, the natural QR target. The visitor scans, finds your poster online, and the exchange continues.

In summary

• A QR code extends the exchange beyond the session (a take-away).
• Point it to a single useful target: paper, data, or companion page.
• Make it big, high-contrast, labeled, and test it before printing.
• The companion page is often the best destination.

Frequently asked questions

Do you need a QR code on a scientific poster?
Not mandatory, but it has become a useful standard: it lets a visitor keep a link to your paper, your data or a web page mirroring the poster, and extends the exchange after the conference.

What should a poster QR code point to?
To a single useful target: the full paper or its DOI, the data, or a web page dedicated to the poster. Avoid multiplying QRs, which compete for attention.

How do I make sure a poster QR code is scannable?
Make it big enough, high-contrast (dark on light, no image behind it), with a clear label, and test it with several phones before printing. Check that the destination link is valid.
