Product Description
 
R4 Smart Ring
IC / ID / NFC card simulation | iOS Android dual platform Cloud Application
 
Micro-crystal
Zr ceramics R4 whole body is entirely made of micro-crystal Zr ceramics. With excellent refractive index and chromatic dispersion, the device emits a unique rounded luster.
 
Marathon process
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.
 
Nano feature
By virtue of the low thermal conductivity of Micro-crystal Zr ceramics, R4 has a gentle touch sense as jade.
 
Possess 4 times the hardness of the aluminum alloy, calmly deal with all kinds of scratches in daily life.
 
The new flagship of smart ring
R4 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.
 
Multi-frequency bands and multi-standards
From 125KHz to 13.56MHz, the R4 can simulate encrypted IC cards or ID cards in a variety of formats,
help you to effectively deal with all-fields card swiping scenes.
 
Personal access card / Public access card
Elevator card / Parking card
Timecard / Medical card
 
Shopping card / Gas filling card
Transportation card / Car key
Membership card / Customized card
 
NFC cloud services flying their own colors
The built-in featured cloud services can be respectively started through the two sets of NFC modules
It can be used directly without APP installation and is Applicable to Android and iOS dual platforms.
 
Independent of fixed phone or APP,
safe, fast, and login free, easy on the trigger of editing and sharing.
 
Waterproof and dust-proof
The dust-proof waterproof level of the R4 is IP68, and it can meet the application requirements of various environments
 
No need to charge
The R4 is driven by the radio energy of the read-write equipment.
Charging is not needed. No need to worry about the battery life. It can accompany you every single day.
 
Size selection
1. When measuring, please use a fine line without elasticity to wind around your finger;
2. Tighten the line slightly, otherwise, the ring will be oversize;
3. After straightening the line, measure its length with a ruler, and choose the size according to the table below.
