Radio frequency identification (RFID)

RFID in product lifecycle management: a case in the automotive industry

“…they are read-only); in contrast, active tags can use greater variability in readers and can be reader at significantly longer distances, while they usually contain facilities to read and write a multiple number of times. There also exist hybrids called semi-passive tags that use small batteries to operate the RFID chip's circuitry, but rely on the reader power for communication (Angeles, 2005;Roberts, 2006). RFID readers act as a form of middleware between the RFID tag and the backend application system; they can operate at three different radio frequency wavebands: low frequency (100-500kHz) for inexpensive, short-to-medium read range and low reading speed; intermediate frequency (10)(11)(12)(13)(14)(15) for potentially inexpensive, short-to-medium read range and medium reading speed; and high frequency (850-950 MHz, 2.4-5.8 GHz) for expensive, long read range and high reading speed (Ollivier, 1995;Roberts, 2006).…”

The use of radio frequency identification to track samples in bio-repositories

“…Passive tags are energized with radio waves emitted from reader/writer antenna, while active tags contain a power source on the tag itself. Semi-passive tags have a power supply onboard for running the tag's circuit and use the antenna's energy to transmit data [11]. Tags are also categorized as either read-only or rewriteable [10].…”

The Design and Implementation of a Wireless Mesh Sensor Network for a Housing Community

“…The idea of automating the living space through wireless control and sensors is on the threshold of becoming commonplace in many homes. RF wireless systems such as ZigBee [2], Bluetooth [3], Z-Wave [4], RFID [5] and Wi-Fi (IEEE 802.11) [6] offer the means to achieve this.…”
