Radio-frequency identification is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves.

What is RFID tag? An RFID tag consists of a small silicon microchip attached to an antenna. The chip itself can be as small as half a millimetre square – roughly the size of a tiny seed. Some RFID tags are thin enough to be embedded in paper.

Disadvantages of RFID  The main disadvantage of RFID systems is high cost.  Although the tags work in harsh environments, the signals from certain types of tags get affected when they come in close contact with certain metals or liquids.  There is no way in which damaged tags can be tracked and replaced by tags that are intact.  Although the tags do not require line-of-sight communication, they can be read within a specified range only.
