3. RFID
RFID = Radio Frequency Identification
Electronic labeling and wireless identification of
objects using radio frequency
Tag carries with its information
a serial number
Model number
Color or any other imaginable data
When these tags pass through a field generated by
a compatible reader, they transmit this information
back to the reader, thereby identifying the object
4. RFID COMPONENTS
A basic RFID system consists of these
components:
A programmable RFID tag/inlay for storing item data;
Consisting of an RFID chip for data storage
an antenna to facilitate communication with the RFID chip
A reader/antenna system to interrogate the RFID
inlay
Application software and a host computer system
5. TYPES OF RFID TAGS
Active
• Use a battery
• Communicate
over
distances of
several
meters
Semi-passive
• Contain built-
in batteries to
power the
chip’s
circuitry.
• Only transmit
data at the
time a
response is
received.
Passive
• Derive their
power from
the field
generated by
the reader
• Without
having an
active
transmitter to
transfer the
information
stored
