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. RFID Tag
 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. Types of RFID Tags
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. Conclusion
 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
