3.  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.  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.  The RFID tag consists of an integrated circuit (IC) embedded in a
thin film medium.
 Information stored in the memory of the RFID chip is transmitted
by the antenna circuit embedded in the RFID inlay via radio
frequencies, to an RFID reader
 3 types
 Passive
 Semi-passive
 Active

6. Active Tags
•Use a battery
•communicate over
distances of several
meters
Semi-passive Tags
•Contain built-in
batteries to power the
chip’s circuitry, resist
interference and
circumvent a lack of
power from the reader
signal due to long
distance.
•They are different from
active tags in that they
only transmit data at the
time a response is
received
Passive Tags
•Derive their power from
the field generated by
the reader
•without having an active
transmitter to transfer
the information stored

15.  Positive
 RFID is a contactless reading technology and can
read through other materials
 Hold more data than barcode does
 RFID tags data can be changed or added
 More effective, bring lots of convenience to us
 Negative
 Cost is relatively remain high (compare to barcode)
 RFID signals may have problems with some
materials
 RFID standards are still being developed
