Was ist ein NFC Smart Ring – und wie funktioniert der digitale Ring am Finger?

What is an NFC Smart Ring – and how does the digital ring on your finger work?

A ring that does more than just look good: The NFC Smart Ring is a stylish wearable with integrated NFC technology. It replaces business cards, opens digital doors, and shares contact information – contactless, battery-free, and elegant.


Whether for everyday use, business, or smart applications: this ring makes an impression and is always ready.

💡 What is an NFC Smart Ring?


An NFC Smart Ring is a finger ring with a built-in NFC chip. This can be programmed as desired – for example, with:

  • a digital business card
  • a URL (e.g. LinkedIn profile, contact form)
  • an emergency contact
  • a smart home action (e.g. door opener)


✅ Advantages at a glance:

  • Stylish & discreet – looks like a modern ring
  • Always with you – no card, no key needed
  • No battery, no charging
  • Contactless & hygienic
  • Reprogrammable at any time
  • Compatible with Android & iOS

🛠️ How it works:

  1. You save your desired information on the ring (e.g. via app or service from TaggyTech).
  2. The NFC chip in the ring remains passive – until a smartphone comes within range.
  3. When you tap it, the saved function opens automatically.

💬 Example:

You meet someone at an event and want to share your contact information. Instead of searching for a business card, simply hold your hand with the NFC ring against their smartphone. Your digital business card opens instantly.
