is about RFID. It can be used to track shipments through a supply chain, animals
(for food traceability like Mad Cow) and all kinds of security systems like
access control and electronic article surveillance. With that range of
capabilities, you might realistically assume that there are many different RFID
chips, different frequencies and different ways to implement the technology. That
assumption is correct!
help you get started, we have provided a non-technical operational overview
about RFID. To do that, it is also important to understand the RFID operating
characteristics compared to other automatic identification technologies like bar
codes (no, every bar code is not going to be replaced by an RFID tag),
biometrics and magnetic stripes.
Introduction to RFID, Bar Codes,
Automatic Identification and Data Collection is
a great place to start..
section on technologies explains the operating characteristics as
well as the attributes and limitations of the various auto id technologies
including: linear bar codes, 2D bar codes, contact memory, RFID, voice and
section covering an Introduction and Identifying
Opportunities helps people understand all the things that can be
impacted by auto id like management information, handling capacity,
throughput, space, sortation, transportation, inventory management, security
section deals with moving data from where something is identified
to where the information can be used. This deals with personal digital
assistants (PDAs) on to local area networks (wireless and mobility) and then on
to electronic commerce.
you are interested, there is a section covering the business case
for using the various forms of automatic data collection. It then goes on to
tell where the technologies are being used.
