is a technology that allows for passive
data capture and the identification of
things using radio waves.
ID numbers and other data can be physically attached
to things via tags and can be read with
radio waves. Radio waves can be broadly
scattered and can penetrate most materials.
This expands the possibilities for capturing
data and identifying things.
systems use a radio transmitter/receiver, antennae
and tags (transponders). The transmitter/receiver
sends radio energy through an antenna then
listens for a response from tags. Tags with
unique ID numbers and other data located
in the radio field receive energy from the
radio transmitter, wake up, and then respond
to the field with a series of pulses. These
pulses are detected by the radio receiver
and decoded to reconstruct the data being
stored on the tag including the tag ID.
technology is creating a revolution in the
business community because it can solve problems
that other traditional technologies have been
unable to solve. Situations where RFID technology
can improve business processes include:
Tough environmental conditions: heat,
humidity, corrosive conditions (ocean, chemical),
cold, UV, etc.
Non line of site applications: behind
walls, inside machines, inside molded parts, inside
bodies, underground, etc.
Labor intensive processes: many items
at one time, passive data capture, eliminating
visual inspections, etc.
High accuracy requirements: hospital,
healthcare, airline, financial applications, etc.
any process that would benefit from passive data
capture can benefit from this technology.
revolution has just begun. More and more, RFID
will change the way the business community works.
Business processes will be built around the technology,
much like bar codes have changed logistics and
supply chain processes forever.
