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 (10) uses an electronic key (12) for storing data. A reading mechanism (14) is provided and is used for reading a modulated signal having the data stored on the electronic key (12) when the electronic key (12) is coupled to the reading mechanism (14). An RF emulating circuit (16) is coupled to the reading mechanism (14) for emulating an RF energy signal to the electronic key (12) for allowing the reading mechanism (14) to read the data stored on the electronic key (12) when the electronic key (12) is coupled to the reading mechanism (14).
Abstract:
A Radio Frequency Identification (RFID) security tag (10) for attachment to a small article of merchandise to monitor the tagged item. The security tag uses a thin flexible strip (12). An RFID tag device (14) is coupled to the thin flexible strip (12) and is used for storing data related to the small article of merchandise to be monitored. A plurality of conductors (16) are laid on the thin flexible strip (12). The plurality of conductors (16) are coupled together to form a multiple turn coil for providing energy to the RFID tag device when a first end (12A) of the thin flexible strip is coupled to a second end (12B) of the thin flexible strip to form a loop.
