3. Definition Radio frequency identification (RFID) a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. It's grouped under the broad category of automatic identification technologies.

It's grouped under the broad category of automatic identification technologies. Passive and active RFID Are used. Passive and active RFID Are used. It was first used by German in II WW for definition of friend and foe. It was first used by German in II WW for definition of friend and foe.

4. RFID Vs Bar Code Some auto-ID technologies, such as bar code systems, often require a person to manually scan a label or tag to capture the data. RFID is designed to enable readers to capture data on tags and transmit it to a computer system without needing a person to be involved  RFID does not need a line of sight

5. Component OF Passive RFID TAG: stores a serial number that identifies a person or object, on a microchip that is attached to an antenna. When it comes in the range of the reader it is energized. The antenna enables the chip to reflect the identification information to a reader. stores a serial number that identifies a person or object, on a microchip that is attached to an antenna.
