~ Use cases

One tag, one job.

One tag, one job. Everything in these boxes is a tag with an NFC sticker inside. Tap it with a phone and it does one thing: opens a page, books a meeting, joins the Wi-Fi. Here are the eight jobs in the Tilde booth’s boxes, what each does on an iPhone and on Android, and how to make your own.

The giveaway box closed: a long khaki base under an olive lid with a khaki QR code, the ~/tilde wordmark with an orange ~/ and tap waves, and taptilde.com.

how it works

  • The sticker does the work. A tap opens whatever was written to it. The other phone doesn’t need an app.
  • Any phone with NFC. Many Android phones have NFC off until you turn it on, and older iPhones (7 to X) need the NFC reader in Control Center.
  • You write it. Tilde for Android writes any of these in a few taps, for free: Cards → Write a sticker, then choose what it opens. On an iPhone, the free NFC Tools app writes a link.
  • You can rewrite it. A phone rewrites the sticker through the plastic, so a tag can change jobs.
  • Anything on a tag is public. Anyone who taps it can read it and copy what’s on it. Put on it only what you’d put on a poster.

The code on the booth’s tags: some of the booth’s tags have a QR code on the front. It opens Tilde’s page (taptilde.com), not what’s on your sticker. A tag you print yourself carries your own link in its code.

in the boxes

The two giveaway boxes open, ten base tags in each stack, icons up. Box 1: Family (a house), Contact card, Link and chat. Box 2: Guest Wi-Fi (Wi-Fi password), Share your number (a handset), Lost item (Found it?) and Book a meeting (booking).

The booth’s giveaway tags are khaki on black, with each job’s icon on the back.

The Link tag from the giveaway box, khaki on black.

A tap opens your website, your LinkedIn or any page.

  • Android and iPhone: a tap opens the link. No typing a URL.
  • Make one: add the link to a card on the Cards tab, then Write a sticker and choose it. On an iPhone, write it with NFC Tools.
  • Keep in mind: use it for yourself too, as a physical bookmark for a page you open every day (see below).

Book a meeting

The Book a meeting tag from the giveaway box, khaki on black.

Tap to book time with me.

  • Android and iPhone: a tap opens your booking page (Calendly, Google Calendar’s booking pages or any other).
  • Make one: add your booking link to a card, then Write a sticker and choose it.
  • Keep in mind: use a booking page that shows only your free times, never your calendar’s details.

WhatsApp

The WhatsApp (a generic chat icon) tag from the giveaway box, khaki on black.

A tap opens a WhatsApp chat with you, with a greeting ready to send. No more “text me your number”.

  • Android and iPhone: a tap opens WhatsApp on a chat with you, the greeting filled in.
  • Make one: add WhatsApp to a card, then Write a sticker → WhatsApp.
  • Keep in mind: the link carries your number, so anyone who taps it can message you.

Contact card

The Contact card tag from the giveaway box, khaki on black.

Tap the tag, save the contact.

  • Android: a tap offers to save your contact card, if it fits the sticker.
  • iPhone: iPhones open links from a tap, not contact cards. For iPhone users, use the Link tag with your website.
  • Make one: Write a sticker → Contact card. An NTAG216 sticker holds a full contact card.
  • Keep in mind: anyone who taps it gets your contact card. In Edit card, uncheck your phone number or email under What they save if you’d rather leave them off.

Guest Wi-Fi

The Guest Wi-Fi tag from the giveaway box, khaki on black.

Friends over? They tap the tag and they’re online. No asking for the password, no typing.

  • Android: a tap offers to connect to your network, and joins.
  • iPhone: iPhones can’t join from a tag: they scan the Wi-Fi code on your phone’s Share screen.
  • Make one: set up Guest Wi-Fi in Tilde’s Settings, then Write a sticker → Guest Wi-Fi (it’s named Wi-Fi if you’ve set up Hotspot too).
  • Keep in mind: use your guest network, never your main one. Anyone with the tag can read the password.

Lost item

The Lost item tag from the giveaway box, khaki on black.

Found this? Tap to call the owner. For your keys or your bag.

  • Android: a tap opens the phone app with your number filled in, ready to call.
  • iPhone: iPhones can’t call from this tag yet: it’s for Android phones.
  • Make one: in Tilde, make a card with your number, then Write a sticker → Phone number and pick Call.
  • Keep in mind: never an address. Keys plus an address is a way in. A first name helps whoever finds it.

Call my family

The Family tag from the giveaway box, khaki on black.

If your child loses their phone, whoever finds them taps the tag on their backpack, and your number is ready to call.

  • Android: a tap opens the phone app with your number filled in, ready to call. No internet needed.
  • iPhone: iPhones can’t call from this tag yet: it’s for Android phones.
  • Make one: in Tilde, make a card with one parent’s number, then Write a sticker → Phone number and pick Call.
  • Keep in mind: one parent’s number is enough. Don’t put on it the child’s name, school or address, or your own address: anyone who finds it can read it.

Share your number

The Share your number tag from the giveaway box, khaki on black.

One tap and your number is ready to call, or a new text to you, without saving a contact.

  • Android: a tap opens the dialer with your number filled in (Call), or a new text to you (Text).
  • iPhone: iPhones scan the code on your phone’s screen instead.
  • Make one: Write a sticker → Phone number, then pick Text or Call.
  • Keep in mind: the text starts empty, and Call only fills in the number: nobody’s phone calls you by itself.

more ideas

The shopping list on the fridge

A white grocery list on a pale fridge door: "groceries" handwritten in navy and underlined, milk and eggs ticked, bread crossed out, and a last row reading "tap for list" with a hand-drawn tap icon; its corner folded over in khaki.

Tap the list on the fridge, and it’s on your phone. Coming in the next app update.

  • Android and iPhone: a tap opens the list on a page, with tick boxes, and no app is needed. Your ticks stay on your phone; they don’t change the list on the fridge.
  • Make one: make the list in Tilde, then Write a sticker to the Grocery list (see Home & desk). To change it, edit it in Tilde and tap the sticker again.
  • Keep in mind: anyone who taps it can read the list.

Physical bookmarks

The demo ring: ten tags on a ring, each a different use, orange on black.

Flip to the tag, tap, and it’s open. A ring of thin tags works like index cards, each for a page you’d otherwise dig for: the parcel you’re tracking, today’s forecast, your gym’s schedule. These are for you rather than to share. Your phone rewrites a tag when the parcel changes, without a reprint.

The demo keychain: flip through and tap any. At the booth, its tags open things like these:

  • a parcel’s tracking page;
  • today’s forecast;
  • a news front page;
  • a team’s scores;
  • a gym’s class schedule;
  • a shared calendar;
  • a booking page;
  • parking nearby;
  • live departures;
  • train times;
  • directions to a place;
  • an email with the subject filled in;
  • a playlist;
  • a restaurant’s menu.

A tracking page can show your name and address on some carriers’ sites, so keep those bookmarks on your own keys.

With just your phone

You don’t need a tag at all: Tilde shares from your phone with a tap or a code.

  • Keep a card for every room: a work card with your title and LinkedIn, and a socials card without your number.
  • Remember who you met: Met lists every tap of your phone, with the time, the card and the event. Add a note, then go through it after the event.

Tilde for Android

how to get one

  • At the Tilde booth at Web Summit: take a tag from the boxes. It’s written for you there, in about 10 seconds.
  • Print your own: coins and tags from github.com/tbutman/tilde-card.
  • Or any NFC sticker: Tilde writes the same things to a plain round NFC sticker, or to a Tilde Card.
