Abstract
A radio frequency identification device (RFID) including radio frequency identification circuitry enclosed in a protective molded casing having an attachment surface for attaching the RFID to a ferrous object, the radio frequency identification circuitry being positioned in the casing so as to keep the circuitry a predetermined distance away from the ferrous object which may interfere with the communication between the RFID and the RFID reader.
Claims7
A method for making a radio frequency identification device (REID) comprising the steps of:
- providing radio frequency identification circuitry;
- pouring curable liquid into a preformed mold to a first predetermined depth;
- allowing a predetermined time to pass to permit the curable liquid to gel, but not sufficient to allow the liquid to fully cure;
- placing the circuitry upon the surface of the now gelled liquid;
- filling the mold to a second predetermined depth with additional curable liquid;
- allowing a second predetermined amount of time to pass to allow both the first and second depths of the poured curable liquid to fully cure and attain a homogeneous interface between the two depths, thereby preventing the occurrence of a seam between the two depths of now cured liquid,
- whereby the radio frequency identification circuitry is positioned within the cured liquid so as to keep the circuitry a predetermined distance away from a ferrous object which may interfere with the communication between the REID and an REID reader.
