This document discusses radio frequency identification (RFID) technology. It begins by defining RFID and its components, including RFID tags, readers, and software. It then covers the different types of RFID tags and their applications in areas like supply chain management, vehicle identification, and access control. The document presents results of an online survey that asked small and medium enterprises about possible RFID applications. It concludes that while RFID provides benefits over barcodes like contactless reading and rewritable data, costs remain relatively high and standards are still being developed.

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

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
