This document discusses radio frequency identification (RFID) technology. It describes the components of an RFID system including RFID tags, readers, and antennas. RFID tags can be passive, semi-passive, or active depending on whether they have an internal power source. Common applications of RFID include payment cards, electronic toll collection, supply chain management, and access control. The document presents results from an online survey about RFID use in different industries and proposes further development areas like medical and library applications. In conclusion, RFID offers benefits like contactless reading and updating of tag data but also has limitations around cost and standardization.

Conclusion

4. 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

5. 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

6. 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

7. 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

17. 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
