RFID technology uses radio waves to electronically identify objects. It consists of tags that store data, readers that interrogate the tags, and application software. There are three main types of tags: passive, semi-passive, and active. Common applications include credit cards, transportation payment systems, toll collection, access control, and supply chain/logistics. A survey found the most suitable industries for RFID are logistics/supply chain, libraries, and pharmaceutical manufacturing. While RFID provides benefits over barcodes like contactless reading and rewritable data, limitations include higher costs and 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
•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
