Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
An RFID tag is an object that can be applied to or incorporated into aany product. Some tags can be read from several meters away and beyond the line of sight of the reader.
Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a (RF) signal, and the other a specialized function. The second is an antenna for receiving and transmitting the signal. A technology called chipless RFID allows for discrete identification of tags without an integrated circuit, thereby allowing tags to be printed directly onto assets at a lower cost than traditional tags.

New advances in microchip technology are creating a tiny revolution
Microchips are becoming so inexpensive to make that they'll soon be in almost everything we buy.
The idea behind the technology, is called RFID (radio frequency identification) chips. An antenna is coupled with a silicon memory chip that can store information such as names, addresses or serial numbers, built into a plastic tag. When it comes within range of a reader, it draws enough power from the radio field to return the information stored on the chip.
SMART BALLS
Football authorities have long considered electronic systems to determine whether the ball crosses the goal line. Adidas has developed a chipped ball that causes the referee's watch to beep if it passes readers in the goalposts. Similar chips in shin pads could perfect offside decisions. The Fifa president, Sepp Blatter, has said he expects a system to be up and running in time for this December's World Club Championship.
