that violates the implication that the RFID tag must touch the RFID reader at a range of 5 - 10 cm. Their system architecture involves two devices, a leech and a ghost, that communicate with each other. The RFID of individuals who might be unaware of the security breach. RFID tags are small devices which can store a limited amount of information. The RFID tag responds to a query from an RFID scanner, relaying information

Passive RFID tags have no internal power supply. The minute electrical current induced in the antenna by the incoming radio frequency signal provides just enough power for the CMOS integrated circuit the incoming signal and also to transmit the outbound backscatter signal. The response of a passive RFID tag is not necessarily just an ID number; the tag chip can contain non-volatile data, possibly writable

RFID stands for radio frequency identification. It is an automatic identification technology, which uses wireless radio communications to uniquely identify objects or people, and is one of bar codes.RFID uses an integrated microchip and antenna that reads information. The combination of the chip and antenna is called an RFID transponder or tag. There are two types of tags, and therefore

to the information written on a printed barcode. RFID tags, however, can be read/write devices; the RFID reader can communicate with the tag, and alter as much of the information as the tag design will allow. RFID secure and less likely to be illegible or be removed. A barcode is usually printed on a products label and can be smudged or removed before it can be used....RFID tags and barcodes both carry information
