When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. [1] Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered ...
Machine reader or scanner. This device reads the encoded data, converting them to an alternative form, typically an electrical analog signal. Data decoder. This component transforms the electrical signal into digital data and finally back into the original alphanumeric characters.

Mobile RFID (M-RFID) are services that provide information on objects equipped with an RFID tag over a telecommunication network. [1] The reader or interrogator can be installed in a mobile device such as a mobile phone or PDA. [2] Unlike ordinary fixed RFID, mobile RFID readers are mobile, and the tags fixed, instead of the other way around.
A wireless identification and sensing platform (WISP) is an RFID (radio-frequency identification) device that supports sensing and computing: a microcontroller powered by radio-frequency energy. [1] That is, like a passive RFID tag, WISP is powered and read by a standard off-the-shelf RFID reader, harvesting the power it uses from the reader's ...
The AAR selected four systems for extensive field tests. General Electric developed an RFID system, ABEX a microwave system, Wabco a black and white barcode system, and General Telephone and Electronics (GTE) a color barcode system called KarTrak. The RFID system used a tag mounted under the rail car and an interrogator installed between the rails.
