This document summarizes RFID technology, including its components, types of tags, and applications. RFID systems consist of RFID tags containing data chips and antennas, and readers that interrogate tags. Tags are either active, semi-passive, or passive. Common applications discussed include payment cards, vehicle toll collection, access control, inventory management, and more. The document also summarizes an online survey of SMEs that found most saw potential for RFID in inventory control, logistics, and library management. It concludes that RFID provides benefits over barcodes but also has higher costs and interoperability challenges.

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

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
Active Tags Semi-passive Tags Passive Tags
• Use a battery • Contain built-in • Derive their power
• communicate over batteries to power from the field
distances of the chip’s circuitry, generated by the
several meters resist interference reader

from active tags in
that they only
transmit data at the
time a response is
received

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
