Event check-in & proof-of-presence promos

Event promos often rely on badge scans or honor-system selfies that are hard to audit afterward. A proof-of-presence campaign asks for a photo at the venue or booth with a handwritten verification code visible—the same anti-fraud approach as product UGC, applied to foot traffic and experiential marketing.

Organizers get timestamped, scored submissions tied to participation records instead of a spreadsheet of unverified social tags.

Real marketing parallels

• Conferences & expos — booth check-in campaigns; lead-quality filter for swag or token drops (crypto conferences, tech fairs).
• Retail & HoReCa — “I was here” at a new store opening or pop-up; drives local social proof.
• Brand-owned events — sponsor lounge or workshop attendance verified before premium rewards.
• Hybrid launches — online audience excluded; only physical presence qualifies, reducing remote farming.

Why brands use it

• Turns attendance into publishable UGC for recap posts and sponsor reports.
• Verification code requirement reduces old photos taken at a similar-looking venue.
• Brief can require brand signage, booth number, or staff sticker in frame.
• Works with small symbolic pools for trials or larger escrow for flagship events.

Campaign sketch

Describe the venue shot in your brief (booth backdrop, signage, handwritten code on a sticker). Optionally enable subsidized participation if you want to cover participant fees during the event window. Staff can demo the flow live at the booth—participants connect a wallet, get a code, shoot, submit, and see score feedback on screen.

After the event, use the public quest page activity and winners sections as a case study for the next sponsor deck.
