The document discusses RFID (radio frequency identification) and its applications. It begins with an introduction to RFID technology and its components, including RFID tags that can be passive, semi-passive, or active. It then discusses various applications of RFID at different frequencies, such as using passive high frequency RFID for smart cards and payment systems, and passive ultra high frequency RFID for logistics and supply chain management. The document also presents results from an online survey of small and medium enterprises on their opinions of RFID and its applications. It concludes with positives and negatives of RFID technology.

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
