Wear it

Slip on a ceramic ring with a secure element sealed inside. Nothing to charge, nothing to sync.

Tap any phone

Hold it to a modern smartphone. The phone powers the chip over NFC and reads your cryptographic key — no app required.

Your portal opens

Your personal portal unlocks in the browser. Your apps, your identity, your world — available from any trusted device.

Engineered ceramic

Built to outlast everything you own.

Most wearables die — batteries fade, metals rust, electronics melt. The Kee Ring does none of that.

  • Battery-free. Passive NFC draws power from the phone. There is nothing to charge, and nothing to wear out.
  • Rust-proof. Ceramic doesn't corrode. Shower, swim, live — it doesn't care.
  • Flame-proof. Withstands heat that destroys ordinary electronics.
  • Scratch-resistant. A surface that stays looking new for years.
