QR Codes for Events: Invitations, Check-in, WiFi and Networking

Events are full of moments where people need information quickly: where to go, how to connect to WiFi, how to add the session to their calendar, how to stay in touch with someone they just met. QR codes handle all of these well. Here's a practical rundown, from invitation to follow-up.

Add-to-calendar codes on invitations

A calendar event QR code contains the title, date, time and location in the standard iCalendar format. Scanning it offers to add the event to the guest's calendar, so they don't forget.

Directions

A location QR code opens the venue in Google Maps. Handy on invitations and parking signs.

Registration

A plain URL code on posters and flyers can send people straight to your sign-up form.

A ticket QR code is only as good as the system that checks it. For real ticketing (where each code must be unique, scanned once, and rejected if copied), you need a ticketing or check-in platform that issues a unique code per attendee and validates it at the door against its own database.

A simple ticket QR code that contains the event name, seat and ticket number (like QRCraft's event ticket type) is useful for small, informal events where staff just need to read the details quickly. It doesn't prevent someone from copying it. Pick the approach that matches how much is at stake.

• WiFi: a WiFi QR code on the registration desk and in each room saves dozens of "what's the password?" questions.
• Schedule and room changes: point a code on your signage to a schedule page. If you use a dynamic code, you can redirect it if the schedule moves to a different page.
• Feedback: a code at the exit or on the last slide of each session linking to a short survey gets far more responses than an email a week later.
• Slides and resources: speakers can put a code on their final slide linking to their deck.

Put a vCard QR code on attendee badges so people can save each other's contact details in one scan, or a LinkedIn QR code for professional events. Ask attendees whether they want their details on the badge first; not everyone does.

If you use dynamic codes, you can see how many times each one was scanned and when. Comparing scans on the registration poster vs. the social post vs. the flyer tells you which channel actually brought people in, which is useful when planning the next event.

• Make venue signage codes big: people scan them from several metres away.
• Test every code at the venue, in the venue's lighting, before doors open.
• Label every code with what it does ("Scan for WiFi", "Scan for schedule").
• Have a fallback: a printed WiFi password and schedule for anyone without a working phone.
