How NFC Pet Tags Work

NFC pet tags use a short-range wireless chip linked to a secure web profile. A tap or QR scan opens owner-controlled pet details.

Definition

How NFC Pet Tags Work: An NFC pet tag contains a passive chip powered by the phone’s magnetic field. The chip returns a URL; the phone opens the pet’s digital ID page.

Step-by-step

From setup to reunion, the flow is simple.

  • Owner creates a pet profile on KediSmart
  • Tag is linked to that profile (NFC + QR)
  • Finder taps or scans the tag
  • Finder sees allowed details and can message the owner
  • Owner arranges a safe meetup

Privacy controls

You choose what finders see — pet name, photo, medical notes, or anonymous contact only. Personal home address should stay private.

Frequently asked questions

What if NFC does not work on a phone?

Use the printed QR code. Camera apps on Android and iPhone can open the same profile URL.
