The document discusses Radio Frequency Identification (RFID) technology, including its components, types of RFID tags, current applications in areas like supply chain management, asset tracking and access control. It also presents the results of an online survey on possible RFID applications and opportunities for further development in medical uses and library management. The conclusion notes both the benefits of RFID's contactless reading abilities and ability to hold more data compared to barcodes, as well as remaining challenges around cost and standardization.

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