Write a link, a note, your Wi-Fi or a contact card to an NFC tag. Nothing sent to a server.
Writing tags needs Chrome on Android — it's the only browser that can talk to NFC hardware from a web page. iPhones don't allow it at all.
You can still fill the form in and see how big your message is. Open this page on an Android phone when you're ready to write.
Tap the tag and the phone opens this page. Short addresses use less of the tag's memory.
Plain text. The phone shows it rather than opening anything.
Android joins the network on tap. Behaviour varies by phone — test yours before you hand the tag to a guest.
Written as a contact card. Contact details take up the most room — watch the meter below.
Read what's already on a tag. Nothing is changed and nothing is stored.
Everything happens on your phone — nothing sent to a server
