A QR code stamp rally is a structured engagement game where participants scan QR codes at multiple stations to collect stamps, complete a card, and redeem a prize. Run well, it's one of the cheapest ways to dramatically lift booth traffic and engagement at any event.
Stations are the places participants will scan a QR code. For a trade show, each station is a booth. For a conference, sessions and sponsor zones. For a tourism trail, each landmark or restaurant. Pick stations that meaningfully spread engagement across the venue.
How many stations does a participant need to scan to complete the card? Most successful events set completion to 60–70% of total stations - meaningful but achievable in the time participants have. Avoid 100% completion unless your event is tightly scoped.
Each station gets its own unique QR code from your stamp card platform. Avoid using the same QR everywhere - you lose all per-station analytics and create gaming opportunities. Print QRs at a comfortable scanning height and avoid placing them under glare.
The welcome QR is what participants scan first. Place it on signage at registration, on the show guide, on lanyards, and ideally announce it during the opening address. Treat the welcome QR as the front door to the experience.
A leaderboard projected on lobby screens or visible from the registration area drives competition and engagement. Even a simple top-10 leaderboard creates urgency.
Set up a central redemption desk where staff verify completion and hand out prizes. Brief staff on how to mark cards as redeemed in your platform to prevent double claims.
Test the participant flow yourself first thing. Walk to each station, scan, and confirm stamps are arriving. Have a backup plan for any signal-poor zones - usually a kiosk station at registration where staff can record stamps on behalf of a participant with a phone issue.
What if a participant's phone dies?
Their progress is saved against their session, so they can resume on another phone with their session link or by re-scanning the welcome QR.
Can the same person complete multiple cards?
Most platforms tie a card to a participant session, so each person has one card. You can configure the rules to allow multiple cards if you want a different game design.
What's the ideal number of stations?
8–20 for most events. Below 8 the rally feels thin; above 20 participants struggle to finish in the time they have.
