Abstract: A radio frequency identification tag device having a sensor input which modifies a tag data word bitstream read by an interrogator/tag detector. The sensor input may be a switch contact(s), digital and/or analog. The sensor input may be voltage, current, pressure, temperature, resistance, acceleration, moisture, gas and the like. Power from the radio frequency interrogator/tag reader may be used to power the circuits of the radio frequency tag device, which in turn may supply power to any sensor connected thereto.

Abstract: A Radio Frequency Identification (RFID) security tag for attachment to a small article of merchandise to monitor the tagged item. The security tag uses a thin flexible strip. An RFID tag device is coupled to the thin flexible strip and is used for storing data related to the small article of merchandise to be monitored. A plurality of conductors are laid on the thin flexible strip. The plurality of conductors are coupled together to form a multiple turn coil for providing energy to the RFID tag device when a first end of the thin flexible strip is coupled to a second end of the thin flexible strip to form a loop.
