JAKCOM R4 Smart Ring – Where Technology Meets Elegance!

Unlock the Magic: IC/ID/NFC Simulation

Imagine a ring that’s not just jewelry but a gateway to convenience. The JAKCOM R4 Smart Ring is your all-in-one solution for seamless interactions. Whether it’s tapping for payments, gym access, or house security – this ring does it all, just using your hands.

The Science Behind the Style:

1. Micro-Crystal Zr Ceramics: The entire body of the JAKCOM R4 is crafted from micro-crystal Zr ceramics. With exceptional refractive index and chromatic dispersion, it emits a unique rounded luster. It’s not just a ring; it’s a statement.
2. Marathon Process: Each ring undergoes a rigorous journey. Forged over 2 days, sintered in a 1400°C furnace for 5 days, and polished a thousand times through CNC precision. It takes 35 days to present this masterpiece before you.
3. Nano Touch: Thanks to the low thermal conductivity of micro-crystal Zr ceramics, the JAKCOM R4 feels as gentle as jade against your skin.
4. Armor-Like Durability: Possessing 4 times the hardness of aluminum alloy, it calmly deals with daily scratches. No more worrying about wear and tear.
5. RFID Magic: The JAKCOM R4 is the fourth generation smart ring, equipped with multiple sets of RFID chip modules. It can simulate four contactless RFID cards – your digital wallet, access pass, and more.
6. Enhanced Design: The newly designed circuit structure minimizes electric field disturbance between modules. Compared to its predecessors, it boasts three times the transmit-receive distance, making it compatible with various card reading devices.
7. Never worry charging: Yes, that's right! Our smart ring harnesses the power of NFC technology to recharge itself, eliminating the need for external charging. Plus, it securely stores data for up to 10 years, ensuring both safety and stability.
8. Size Measurement:
   • To find your perfect ring size, follow these steps:
     1. Wind a fine, non-flexible thread or rope around the finger where you’ll wear the ring.
     2. Ensure the rope isn’t too tight; keep the error within 1 mm.
     3. Straighten the rope and measure its length with a ruler.
     4. Refer to the following table for ring sizes:
