Conference badges usually carry a name and nothing else, so a good conversation ends with a hunt for a business card. This free tool builds a digital name badge with a QR code that links to a profile, poster, or project page, so the next step after meeting you is one scan away.
What the tool does
You enter a name, affiliation, role, and an optional link. The tool renders a simple badge with those details and generates a QR code below it, using the public qrcodejs library loaded from a CDN. Scanning the code opens the link you gave, or, if you gave no link, the badge text itself. If the library fails to load, for example on a poor connection, the tool says so and shows the badge text instead of a broken image, so you still have something to print or photograph.
How to use it
Fill in the name exactly as you want it read aloud, and keep the role short: postdoctoral researcher reads better than a full job title. Paste the link to the page you most want people to visit, such as a poster PDF, a personal page, or a project site, and test the code with your own phone before printing. Print the badge large enough that the code scans from a comfortable distance, and check it again after printing, since small or low-contrast codes fail most often.
Worked example
Ana Ruiz, postdoctoral researcher at the University of Seville, links her conference poster page. Her badge shows her name, role, and affiliation, with a QR code beneath. A colleague scans it during a coffee break and opens the poster on their phone, instead of writing down a name to search later. If Ana leaves the link blank, the code carries her name, role, and affiliation as text, which still saves the other person typing. Either way, the conversation has a next step.
Reading the results honestly
A QR code is only as useful as its destination. Link to a page that loads fast on a phone and works without a login, because a code that opens a paywalled or broken page is worse than no code at all. Also consider privacy: anyone who photographs your badge can follow the link, so do not link to a page with personal details you would not share with a stranger. For a poster session, link to the poster; for a job search, link to a CV page you control.
Honest limits
This tool depends on an external QR library from a public CDN. If that library is unavailable, the code will not generate, and the tool falls back to text, which it states plainly. The badge is a simple on-screen design, not a print-ready conference credential, and it does not store badges, manage registrations, or verify identities. Print quality, paper, and lighting all affect scanning, so always test the printed result.
Practical tips
Pair the badge with a one-line conversation opener on the back, such as the question your poster answers, so people remember why they scanned. If you present a poster, put the same QR code on the poster itself, since many visitors photograph posters without stopping to talk. Replace the link after the conference if it pointed to a temporary page, so late scans do not hit a dead end.
What to link for different goals
Choose the destination for the reader, not for yourself. A recruiter wants a CV page, a collaborator wants a project page, and a conference visitor wants the poster. If you must serve several audiences, link to a single landing page with three clear buttons, so one scan serves everyone without forcing a choice at the badge.
