  2. Outlines: RFID Definition RFID Vs Bar Code Components Proposed design of an Active RFID

  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. • Passive and active RFID Are used. • 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. READER: converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it.

  6. Active Tag Active Tag does not have to be energized by the reader. It has its own power to send. Passive Active
