RFID & Its Applications The document discusses Radio Frequency Identification (RFID) technology, including its components, types of tags, applications, and a survey on potential industries for adoption. It provides an overview of RFID, describing tags, readers, and system setup. Common applications include access control, toll collection, logistics/supply chain. A survey found potential in logistics, libraries, and pharmaceuticals. Further development opportunities in medicine and libraries were noted. The conclusion discussed pros of contactless reading and data updating, but also high costs and signal interference challenges.

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
ActiveTags
• Use a battery
• communicate over
distances of several
meters
Semi-passiveTags
• 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
PassiveTags
• 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
