Patent attributes
The present invention winds an antenna wire of a NFC (Near Field Communication) chip and antenna component round inside a hard concave ring, which is then encapsulated in a room temperature-solidifiable resin adhesive. If metal material is used, then a repeater material is disposed between the metal and the NFC chip and antenna component to prevent interference thereto. The present invention thus resolves the frequently seen shortcomings of NFC circuit component failure because of the high temperature when encapsulating, poor waterproofing, and the main body of the ring being too wide. In particular, wearing the NFC ring device on a finger reduces the sensing distance of the NFC device to a minimum, and prevents data from being stolen. If there are abnormalities in receiving and transmitting information, then taking off the ring and placing the circumferential plane of the ring close to the NFC sensor improves the situation.
