LAB

Tap a badge. Keep the person.

Paper name badges with an NFC tag on the back. One tap and you both have the other's name, company and LinkedIn, with no app to install.

Use it at your event

Meet someone. Their badge has the same tag as yours.
Hold the back of your phone on their badge for a second.
You both get each other. Nothing to type, nothing to send.

One tap fills two lists.

Claim a badge at the door. Tap it and pick your name from the guest list, and your company and LinkedIn fill themselves in, which takes about thirty seconds once for the whole evening.
Tap someone else's badge. Their card opens on your phone with their LinkedIn one press away, and you land on each other's list.
Take the list home. The next morning you have everyone you met with their links, as a spreadsheet or straight in your phone contacts.

Company Brainmaxxing, Berlin, 30 September 2026.

I co-organised this meetup, brought 40 badges and asked nobody to install anything or hand over an email address. 33 guests claimed a badge, 31 of them with their LinkedIn on the card.

Problem. Most people you meet at a meetup are gone by the next morning, as scanning each other's LinkedIn QR code is slow enough that people stop after a few conversations, and a handwritten badge only gives you a first name.

Built. Paper badges with an NFC sticker and a QR code as a fallback, with the guest list pulled from Luma so checking in is picking your own name. A screen in the room ran on the same data, showing who was on stage, the live vote and an anonymous map of who met whom.

Result. 33 guests claimed a badge, 43 pairs met and 54 LinkedIn profiles were opened, and the vote on a company brain ended 5 build, 5 buy and 5 not yet. Next time I would use a lanyard instead of a chest badge and let people choose their table on arrival, and the hybrid mode for remote speakers and guests is already built.

What you get if you run it at your event.

Badges printed and set up before doors, for your guest count.
Your Luma guest list loaded, so check-in takes about thirty seconds per guest.
A host board on your phone: who checked in, which badge they hold, an attendance list to download, and one press to move the evening back if it runs late.
A screen for the room that follows your agenda by itself: who is on stage with a QR code to their LinkedIn, the line-up, and a live vote at the time you set.
Every guest leaves with the list of people they met.

No app or account, and no email addresses stored. Guests choose what their card shows, can delete it at any time, and everything is deleted 30 days after the event.
