Riny / lock and key


Riny, a technical ring helps us to use the inductive technology more intuitively. An inductive card is reformed into ring-shape: copper wire is embedded into a ring made of medical resin and connected to the RFID chip without affecting the function. Furthermore, we developed a technology named VCL(Virtual Combination Lock), which emitted infrared ray scanning on the barcode of the ring, and thus to compute the rotation angle. VCL allows us to use key-holding hand gesture, and spin our wrists to unlock the combination lock.
Riny is waterproof, and harmless to human body so we can wear it all day and the inductive card is just on the finger.
