The document discusses RFID (radio frequency identification) technology, including its components, types of tags, applications, and future opportunities. An online survey found that logistics and supply chain management was seen as the most possible application area for RFID. The technology is seen as having benefits like contactless reading and holding more data than barcodes, though costs remain higher than barcodes and standards are still being developed. Further development is seen in medical and library management uses.

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

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
