NFC Smart Ring
The smart ring is a fashionable and wearable electronic product which is able to connect with a smartphone through Near Field Communication (NFC) to complete function performing and data sharing. Designed with high-level water resistance, it can be used without any power supply. Embedded with NFC chip, it can only be connected to a smartphone with NFC function.
Place the smart ring within the NFC area of a smartphone to perform: screen unlocking, app lock unlocking, app quickly launching, name card and URL information sending and reading, etc.
Start the NFC APP, perform actions according to the instructions. Since NFC is a near field communication technology, Align the black wafer on the surface of the ring with the NFC position near the camera on the back of your phone so that it can be sensed!This sensing distance is only 1-2 mm to avoid the failure in reading and writing.
