Collecting reviews & followers at events: NFC + QR at the booth

Trade fairs, markets, pop-up stores, company events: nowhere else do you meet so many genuinely interested people in so little time — and nowhere does that interest evaporate faster if you don't capture it immediately. With NFC and QR codes at your event booth you turn visitors into Google reviews, followers, and newsletter contacts — and afterwards you can measure exactly what each event delivered.

Why events are the perfect review moment

At an event the mood is good, the conversation fresh, the smartphone already in hand. That's when the barrier for “quickly review us on Google” or “follow us on Instagram” is lowest. Follow up by email the next day and you lose most of it — the conversion happens at the booth or not at all.

The setup: NFC stands and badges at the booth

• Stand on the counter: “hold your phone here & review” — the NFC stand opens the Google review dialog in seconds; the QR code catches older devices.
• NFC badge on staff: during a conversation, a quick tap of the visitor's phone on an NFC badge on the lapel opens your Instagram profile or contact page — no stacks of business cards. If you prefer handing something over, use an NFC business card.
• Different targets per event phase: newsletter sign-up in the morning, Google review in the afternoon, discount landing page on the last day — with dynamic tags you retarget anytime without reprinting.

Track per event: which appearance delivers?

The crucial trick: a dedicated tag or stand per event — not the same one for everything. Then the scan statistics show in black and white how many contacts the Dortmund fair generated versus the weekly market booth. Same logic as tracking across multiple locations — applied to time periods instead of places.

Metrics for the event debrief

• Scans per event day: morning vs. afternoon shows when your booth works.
• Scans per event year-over-year: which fair is worth the booth fee — and which isn't?
• New reviews/followers during the event window: the actual conversion behind the scans.

Three practical rules for more scans at the booth

• Offer actively: “just hold your phone here” beats any sign. Staff should demonstrate the tap.
• One goal per moment: one stand with one clear call to action converts better than three competing codes side by side.
• Visibility: eye level, good lighting, short call to action — the same rules as for the QR code at the counter.

Who is even allowed to review at a fair

The point most often missed at fairs: a review requires a genuine experience. Google explicitly permits soliciting reviews that reflect a genuine experience — and prohibits content created because of an incentive. Competition law says the same: fake consumer reviews sit in the annex to the German Unfair Competition Act. A booth visitor who stood at your table for two minutes is not a customer.

That leads to a clear split: existing customers dropping by at the fair may and should be asked — they have the experience. Everyone else gets a different target. That is not a sacrifice but the better conversion: for a first contact, following a profile or booking an appointment is the more fitting next step anyway.

After the fair: repoint instead of discarding

When the target lives in a redirect, the hardware is not used up once the booth comes down. The badges that pointed at the fair page for three days point at the company profile or the review page from Monday — same badges, one entry in your account.

In practice that also means you can switch the fair page off after the event without printed material leading nowhere. That is exactly what happens with hard-coded chips and with QR codes printed straight onto an event URL.

Conclusion

Events are conversion moments with an expiry date: collect reviews, followers, and contacts at the booth, or never. Dedicated tags per event also make each appearance measurable — so the next booth-fee decision is based on numbers, not gut feeling. For equipping fairs at volume: our business terms.
