RFID - Radio Frequency Identification Tags....!
Radio Frequency Identification ( RFID ) has existed in some form or another for over 40 years. It is a method of automatically identifying a given object/person by storing and remotely retrieving information from small transponders, called RFID tags. These tags have an antenna built into them, which allows for the transmission and reception of radio waves from an RFID...

Table 1. Comparison of the Typical RFID Read Range According to Frequency Band (Passive Tags)
While Table 1 compares the read range of passive tags, note that there are actually three RFID tag types: active, passive, and semiactive. Because active and semiactive tags use an onboard power source to power the tag response, they are typically capable of much longer read ranges. Passive tags, on...
RFID-radar - A new identification technology - Introduction
These are very sophisticated transponders that are attached to expensive military hardware in warehouses for locating where the "Military tank is parked". The transponders cost more than US$1000 each and the warehouse has to be fitted with ranging beacons all over the warehouse to provide triangulation.
GPS units fitted in each...
