This document provides an overview of RFID (Radio Frequency Identification) technology including its components, types of tags, and applications. It discusses how RFID systems work and consist of RFID tags with stored data, antennas to facilitate communication with readers, and software to process tag information. Common applications mentioned include payment systems, access control, toll collection, logistics/inventory tracking. The document also shares results of an online survey on potential RFID uses and provides a brief video and conclusion on both benefits and limitations of the technology.

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

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
