This document discusses RFID and its applications. It begins with an introduction to RFID, describing its components and different tag types. It then outlines several common applications of RFID technology, including payment cards, electronic toll collection, access control, and supply chain management. The document also presents results from an online survey that found logistics, libraries, and inventory control to be industries respondents thought RFID could be applied. It concludes that while RFID provides benefits like contactless reading and rewritable data, costs remain relatively high compared to barcodes and standards are still in development.

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
