RFID screw specifically for use on eyeglass frames

1. An RFID tag for use on eyeglass frames, wherein the eyeglass frame includes a pair of eye wires or rims surrounding and holding a pair of lenses in place in a front frame, a pair of end pieces that connect the pair of eye wires or rims, respectively, via a pair of hinges, respectively, to a pair of temples, respectively, wherein the pair of hinges connecting the pair of end pieces of the front frame to the pair of temple/eye pieces, respectively, allow a pivoting movement of the pair of temples with a pair of RFID screws being a pair of hinge pins thereof, respectively, wherein the pair of temple/eye pieces on either side of the skull, respectively, are pivotally attached to the pair of end pieces, respectively, by the pair of hinges, respectively, and wherein said RFID tag comprising:

a) an integrated circuit for storing and processing information that modulates and demodulates radio-frequency (RF) signals;

b) means for collecting DC power from an incident reader signal; and

c) an antenna for receiving and transmitting the signal so as to form a transmission;

wherein information from said RFID tag is stored in a non-volatile memory;

wherein either fixed or programmable logic processes transmission and sensor data, respectively;

wherein in order to have read/write ability, said RFID tag uses a class 2 gen IC to embed the RFID tag into a screw shape; and

wherein essentially, said antenna is shaped as said screw and is a coil design approach.

2. The RFID tag of claim 1 , wherein said RFID tag is made of one of high end plastic and silver ink.

3. The RFID tag of claim 1 , wherein said coil antenna utilizes near field magnetic induction coupling at 915 MHz.

4. The RFID tag of claim 1 , wherein total diameter occupied by said coil antenna, including a conductive rod hosting the coil, is roughly 1.054 mm;

wherein 0.346 mm space is left in consideration of thickness for a screw enclosure; and

wherein to adapt to limited space, an insulated coil occupies more space so said coil antenna is made from bare wire and uses a hard plastic body for the screw to avoid any interference a metal body causes.

5. The RFID tag of claim 1 , wherein said RFID tag measures only 1.25×1.25×0.55 mm and incorporates said high-powered antenna into a multi-layer ceramic substrate; and

wherein a widest part of a screw head is just less than 1.30 mm.
