The document discusses RFID technology including its components, types of tags, applications, and survey results. RFID systems consist of tags, readers, and software. Tags can be passive, semi-passive, or active. Common applications include asset tracking, supply chain management, electronic toll collection, and smart cards. A survey found potential uses in inventory control, logistics, libraries, and security. Further development of RFID is seen in medical and library applications.

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
• communicate over batteries to power the from the field
distances of several chip’s circuitry, resist generated by the
meters interference and reader
circumvent a lack of • without having an
power from the reader active transmitter to
signal due to long transfer the
distance. information stored
• 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
