Print your own In Case of Emergency (ICE) keychain with built-in NFC functionality – a practical, modern safety essential for everyday carry.
This compact, round keychain features the classic star of life (red medical emergency symbol) with bold "IN CASE OF EMERGENCY" text arched around the top. Below the star sits "ICE" in large letters, with a subtle WiFi-like NFC symbol underneath, clearly indicating the smart tech inside.

The design uses a clean two-tone layout:

A sturdy keyring loop is integrated at the top, making it easy to attach to keys, bags, or lanyards.
