How CallKin works

Last updated: 22 September 2026

Once you have a CallKin band, here's what happens on the app side, from unboxing to your first scan.

1. 1

   Get your band

   CallKin bands aren't available to order yet, we'll open sales as soon as we're ready. Each one will ship with a unique tag and no personal information printed or stored on it. The steps below cover everything that happens once you have one.

2. 2

   Create your account

   Sign up as a guardian with your name, phone number, and email. This takes about a minute and doesn't require the band yet.

3. 3

   Add a child

   Add a first name and pick an avatar color for the person the band is for, usually your child. We don't ask for a last name, a photo, or any medical details.

4. 4

   Tap the band to claim it

   Scan the band with your phone once while logged in. That links the band's tag to your child's profile. No app to install, just a regular NFC-enabled phone.

5. 5

   Anyone who scans it sees only what you chose to share

   If the band is ever found, a tap from a phone with NFC opens a page showing your name and phone number, nothing more, unless you've chosen to hide even that. Nearly every iPhone and Android sold today can do this without an app, but a phone without NFC, or with NFC switched off, cannot open the band.

6. 6

   Turn on lost mode if you need to

   If the band, or the person wearing it, goes missing, flip the lost-mode toggle in your dashboard. Anyone who scans the band then sees a clear alert alongside your contact details.
