RFID technology allows for wireless identification of objects using radio frequency signals transmitted between tags attached to objects and readers. The document discusses RFID components, types of tags, current applications including access control, asset tracking, authentication, and supply chain management, as well as results from an online survey on potential applications. Further development opportunities exist in medical uses and library management. While RFID provides benefits over barcodes like storing more data and contactless reading, limitations include relatively high costs and potential signal interference from some materials.

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
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
• Derive their power
from the field
generated by the reader
• without having an
active transmitter to
transfer the
information stored

CONCLUSION
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
