This document discusses RFID (radio frequency identification) technology, including its components, types of tags, applications, and a survey of potential industries for adoption. It provides an overview of RFID systems, describing the basic elements of tags, readers, and software. Examples of current applications mentioned include payment cards, electronic toll collection, and asset tracking. The survey found that respondents saw potential for RFID in logistics, libraries, inventory control, and security. In conclusion, benefits are contactless reading and storing more data than barcodes, while costs remain relatively high and standards are still being developed.

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
