FDferndz Smart Wearable Finger Ring: NFC technology for contactless payments

Smart Wearable Finger Ring — Biometric Security, FDferndz

For anyone who juggles keys, cards, and passes daily, this smart NFC ring simplifies access control and transit payments with a simple tap. It’s designed for urban commuters and office workers who need a hands-free, secure way to manage their day.

While many focus on security, this ring offers a hidden benefit: it keeps your essentials safe from loss or theft. The ceramic build feels smooth and durable, and its IP68 rating means it survives rain or accidental spills. You can encode it for your building access, and the NFC chip reads reliably from a few centimeters away—no more fumbling at the door.

Customize the ring to your exact size for a comfortable fit, and enjoy how it seamlessly integrates with systems like public transport. It’s a small upgrade that makes busy routines feel effortless.

  • Waterproof IP68 rating for durability
  • Multiple chip compatibility for versatile use
  • Customizable sizes from US 4 to 15
  • Passive power source for long life
