BRIEF HISTORY
•Invented and used from (Early 1940’s).
•Commercial Operation begun from 1960’s.
•In 1970s developers, inventors, companies,
academic institution and government sectors had
actively worked on RFID .

WHAT IS RFID SYSTEM ?
RFID (Radio Frequency Identifier) data collection
system using RF waves for Identifying, Tracking .

DISADVANGES
• Does not penetrate or transmit around metals(iron ,steel).
•Large antennas compared to higher frequencies.
•Reader collision occurs when the signals from two or
more readers overlap. The tag is unable to respond to
simultaneous queries.
•Active RFID tags can be repeatedly interrogated to
wear the battery down, disrupting the system.

FUTURE ASPECT
Some vendors have been combining RFID
tags with sensors of different kinds. This
would allow the tag to report not simply the
same information over and over, but
identifying information along with current
data picked up by the sensor.

CONCLUSION
RFID technology is taking off in different areas. Due to its
customizable feature and continuing improvement the
communities are beginning to get involved in its
development. It is easy to envision that, the RFID tags
contents will increase in power, prices are expected to
decline and tag will dramatically improve its efficiency,
security and accuracy.
