This document discusses Radio Frequency Identification (RFID) technology. It provides information on RFID components, types of RFID tags including passive, semi-passive and active tags. Applications of RFID technology at different frequencies are also outlined. The document then summarizes the results of an online survey conducted on RFID applications for small and medium enterprises. It concludes by discussing further potential developments in RFID and providing a brief pros and cons analysis of the technology.

4. 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

5. 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

6. 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

7. TYPES OF RFID TAGS
•Use a battery
•communicate over distances of several meters
Active 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
Semi-passive Tags
•Derive their power from the field generated by the reader
•without having an active transmitter to transfer the information stored
Passive Tags

16. 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
