What is RFID?
Radio Frequency Identification
The ability to identify someone or something through the receipt of some kind of radio signal.
Identification
Assign IDs to objects
Link the ID to additional information about the object
Link the ID to complementary info
Find similar objects
Auto-ID Technologies
Automatic identification and data capture refers to the methods of recognizing objects, getting information about them and entering the data or feeding it directly into the computer systems without any human involvement.
Redefining RFID…
Radio frequency identification (RFID) is a generic term that is used to describe 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.
History Of RFID…
First Bar code patents – 1930s
First use of RFID device – 2nd world war – Brittan used RFID-like technology for Identify- Friend or Foe
Harry Stockman October 1948 Paper – Communication by means of reflected power ( The proceedings of the Institute of Radio Engineers)
First RFID Patent - 1973
Auto-ID center founded at MIT – 1999
Standardization effort taken over by EPC Global (Electronic Product Code)
Current thrust primarily driven by Wal-Mart and DoD
Automate Distribution:
Reduce cost (man power, shipping mistakes)
Increase sales (keep shelves full)
DoD Total Asset Visibility Initiative
RFID readers
Reader functions:
Remotely power tags
Establish a bidirectional data link
Inventory tags, filter results
Communicate with networked server(s)
Can read 100-300 tags per second
Readers (interrogators) can be at a fixed point such as
Entrance/exit
Point of sale
Readers can also be mobile/hand-held
