What is RFID? What are the components of an RFID system? How does it work?
RFID-Reader RFID-Tags
Active tags (not covered) Passive tags
Enterprise Network
What are the business opportunities? What are the privacy and security implications?
Proposed Solutions
RFID is Radio Frequency Identification. General concept known as non-contact identification. Similar to barcodes, but does not require line-of-sight. Contains orders of magnitude more information than current alternatives.
UPC Symbol=10 digits, RFID=100's-1000's of digits
RFID is not new
1948: Harry Stockman, "Communication by Means of Reflected Power" explored the electromagnetic theory used in current passive tags. 1975: Los Alamos Labs, "Short-range radio-telemetry for electronic identification using modulated backscatter" applied passive communication to identification. Numerous technical standards: ETSI, ANSI, ISO, JTC, EPC 350+ patents on RFID technology
