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

15. 16. 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
Conclusion
