NFC Ceramic Ring
The Smartest Accessory You'll Ever Wear: Rsmart Ceramic NFC Ring
What is an Ceramic NFC Ring
An NFC ceramic ring is a passive, battery-free wearable that combines premium jewelry aesthetics with powerful contactless technology. Embedded with a high-performance RFID chip and antenna, it enables instant tap-and-go interactions with any NFC-enabled smartphone, reader, or payment terminal.
Rsmart's ceramic ring series – WaveTap and LumiTap – are crafted from high-grade ceramic, a material known for its scratch resistance, hypoallergenic properties, and luxurious glossy finish. Each ring weighs only 4–5 grams and houses the Infineon Secora Connect S chip (ISO 14443 on demand), the same technology trusted by leading payment solutions worldwide.
Available in sizes 6–14 with a minimum order quantity of just 50–100 pieces, these rings are not just accessories – they are keys, wallets, ID cards, and business cards, elegantly worn on your finger.
