The whole body is entirely made of micro-crystal Zr ceramics.
With excellent refractive index and chromatic dispersion, the device emits a unique rounded lustre.
Each ring needs to undergo forging for 2 days, sintering in a 1400 ℃ furnace for 5 days, thousand times of CNC polishing, coating, and other post-procedures. It takes 35 days to present the ring in front of you.
By virtue of the low thermal conductivity of Micro-crystal Zr ceramics, JAKCOM R4 has a gentle touch sense as jade.
New Flagship of Smart Ring
It is the fourth generation smart ring, it carries multiple sets of RFID chip modules. And is capable of simulating four contactless RFID cards. Once again, it becomes a new flagship product.
Brand New Design, Brand New Breakthrough
The newly designed circuit structure has greatly reduced the electric field disturbance between the modules. Compared with the previous generation of products, it has increased the transmit-receive distance by three times and can be easily compatible with a variety of card reading devices.
