The Complete Guide to Using QR Codes at Events and Conferences

Events are one of the highest-density QR code environments in existence — and also one of the most under-exploited. Most event organisers deploy one or two QR codes and stop there. The organisers who do it right deploy a dozen, each solving a specific friction point, and end up with measurable data on attendee engagement across every touchpoint.

This guide is a complete playbook. You don't need to implement everything — but knowing the options lets you prioritise the highest-value deployments for your specific event.

Before the event: save-the-date and calendar QR codes

The first QR code that should go out is on your event invitation or save-the-date communication. An Event QR code encodes an .ics calendar file — when scanned, the attendee's phone prompts them to save the event directly to their calendar (iOS Calendar, Google Calendar, or Outlook) with the title, date, time, location, and description pre-filled.

This single step dramatically reduces no-shows. Attendees who save an event to their calendar are significantly more likely to attend than those who intend to but don't set a reminder.

Include the .ics QR code on:

• Email invitation (as an image)
• Printed postal invitations
• Social media graphics ("Save to calendar: [QR code]")
• Event website footer

At registration: WiFi and programme access

Registration is the highest-traffic touchpoint of any event. Two QR codes belong here without exception:

WiFi QR code

Print an A3 or A2 WiFi QR code poster at the registration desk. Attendees scan and connect to the event WiFi instantly — no password to distribute, no staff time spent answering WiFi questions. For large events (500+ attendees), create separate WiFi QR codes for different zones (main hall, exhibition floor, networking area).

Digital programme QR code

Link a URL QR code to your live programme page or schedule app. This is where dynamic codes prove their value: if a session is moved, cancelled, or modified, you update the destination URL and every printed QR code immediately reflects the change — without replacing a single badge or programme.

Session and programme QR codes

Create a unique QR code per session room. Place it on the room door, on the session description in the programme, and on the screen during the intro slide. Each code can link to:

• The session description and speaker bio
• Slides or resources shared by the speaker
• A live Q&A submission form
• The feedback form for that specific session

Using separate codes per session lets you measure session-level engagement — which sessions get the most resource downloads, which Q&A forms get the most submissions. This data is valuable both for your own planning and for post-event sponsor reports.

Sponsor activations

Sponsors pay for visibility. QR codes make that visibility measurable. Create a unique QR code for each sponsor's stand, badge lanyard insert, or brochure. The analytics show exactly how many attendees scanned each sponsor's code — data you can include in your post-event sponsor report as evidence of ROI.

Sponsors can use their QR code to link to exclusive content, discount codes, product demos, or lead capture forms. Business plan users can add retargeting pixels so attendees who scan a sponsor's code are automatically added to the sponsor's remarketing audience.

Networking and badges

Event badges are one of the highest-ROI QR code placements in the event industry. Print a vCard QR code on every badge lanyard insert. Attendees who want to connect scan each other's badges — no business card exchange required, no typo risk, no lost cards.

For the organiser, this is also a networking facilitation tool. Attendees who scan badges are actively engaging with each other. If you track badge QR code scans (each attendee has a unique code), you can measure which attendees are most networked — useful for understanding which sessions or networking formats are generating the most connections.

Feedback collection

Post-event feedback collection has historically suffered from terrible response rates. Email surveys sent two days after an event get opened by perhaps 20% of attendees and completed by 5–10%. A QR code on the exit from each session, or on the back of the badge, captures feedback in the moment — when the experience is fresh and the attendee is still engaged.

Use a Feedback QR code for quick 1–5 star ratings with an optional comment. For longer surveys, use a URL QR code pointing to a Typeform or Google Form. Place feedback codes:

• On session room exits (scan as you leave)
• On the back of the badge (scan at any point)
• At the event exit alongside a thank-you display
• On the goodie bag or conference materials bag

Post-event analytics

The analytics from your event QR codes tell a story that no other data source can: which sessions, stands, and resources had the highest engagement; when engagement peaked during the day; and which attendee segments (by device type or geography) were most active.

Group all your event QR codes in a single Unqode SmartQR folder named after the event. After the event, review the analytics dashboard and extract the key metrics for your post-event report. See the analytics guide for a breakdown of every metric available.
