Share your socials. Keep your number.

Most ways of sharing yourself give everyone the same thing. A business card, a contact QR code or a single-chip NFC tag hands over whatever is on it, to whoever asks.

So you pick one of two bad options. Put your number on it, and a stranger at a party has it. Leave it off, and the people you actually want to stay in touch with get your Instagram and a “DM me your number” later.

A two-sided NFC wristband fixes that by giving each audience its own chip.

• Larp, the outside of your wrist. The chip under the raised face. Public by design: the socials you don’t mind anyone seeing.
• Alt, the inside of your wrist. The Alt chip is a thin NFC tag sealed on the inside of the band's bottom, against your wrist, so you won't see it from outside. Flip your wrist and tap the bottom of the band. Private by design: your number and the ways to reach you directly.

Each chip has its own link and opens its own page. Your Larp page doesn’t link to your Alt page, so tapping the outside never leads anyone to your number.

These are the defaults. They’re a good starting point for most people.

• Larp: Instagram, LinkedIn, Discord, Snapchat, TikTok, X, GitHub, YouTube, Spotify and Website.
• Alt: Phone, Email, WhatsApp, Telegram, Venmo and Cash App.

Put any link on Larp, Alt or both, and change it anytime in your dashboard. You might keep LinkedIn on Alt for work contacts only, or move Snapchat there if it’s just for close friends. It’s your call, link by link.

NFC only reads within a few centimetres, so nobody can pick up either chip from across the room. The Alt chip also sits against the skin on the inside of your wrist. To reach it, you flip your wrist and offer the bottom of the band. It doesn’t happen by accident.

In practice: hold out your wrist for anyone, flip it for the people you trust. The tapping itself is covered in how NFC wristbands work.

Be realistic about this part. Your Alt page is a web page, so anyone who tapped it can keep the link, and anyone who saved your contact keeps that too. Sharing your number is still sharing your number.

What you keep is control over what the link shows from now on:

• Change or remove links on your Alt side any time. The page updates the moment you save.
• Switch the whole band off from your dashboard if you lose it. Taps stop showing your pages until you switch it back on.
• Nothing to wipe on the chip. It only ever held a link, never your details.

The person tapping sees only the page for the side they tapped. If they press Save contact, their phone gets the details from that side, nothing from the other.

You see when you were tapped and an approximate city. Never their exact location, and never who they are, unless they choose to send their details back. We never sell data. What we store, and why, is in our privacy policy.

If you’re setting up for the first time, get the Larp side right first: that’s the one most people will tap. Share your Instagram with a tap walks through it, and the NFC wristband page covers the band as a whole.
