Description: RFID is an area of automatic identifi cation that is gaining
momentum and is considered by some to emerge as one of
the most pervasive computing technologies in history. In its
simplest form, RFID is a similar concept to bar coding. It is
seen as a means of enhancing data processes and is comple-
mentary to existing technologies. It is a proven technology
that has been in use since the 1970s.-Amore complex description is an electromagnetic proxim-
ity identifi cation and data transaction system. Using ‘‘RFID
tags’’ on objects or assets, and ‘‘readers’’ to gather the tag in-
formation, RFID represents an improvement over bar codes in
terms of non-optical proximity communication, information
density, and two-way communication ability. Operational
RFID systems involve tags and readers interactingwith objects
[assets] and database systems to provide an information and/
or operational function.
RFID is used for a wide variety of applications ranging from
the familiar building access control proximity cards to supply
chain tracking, toll collection, vehicle parking access control,
retail stock management, ski lift access, tracking library
books, theft prevention, vehicle immobiliser systems and rail-
way rolling stock identifi cation and movement tracking. Platform: |
