How it works

  1. Order your band

    One adjustable silicone wristband with an NFC chip inside.

  2. Tap it to link it

    Create a free CallKin account, then tap the band with your own phone. Takes about 10 seconds.

  3. Anyone can reach you

    If your child is lost, whoever finds them taps the band and sees how to call you.
