This document discusses RFID (Radio Frequency Identification) and its applications. It begins with an introduction to RFID components including tags, readers, and antennas. It then discusses different types of RFID tags and their characteristics. Several current applications of RFID are presented, including use in credit cards, transportation cards, and electronic toll collection. An online survey about RFID applications is described that found logistics, libraries, and pharmaceuticals to be top areas firms think RFID could be used. The document concludes with positives and limitations of RFID 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
