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
RFID

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
RFID components

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

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
Conclusion
materials
◦ RFID standards are still being developed
