RFID is a technology that uses radio waves to identify objects electronically. It consists of tags that carry data, readers that can interrogate the tags, and software. There are three main types of tags: passive, semi-passive, and active. Common applications include access control, asset tracking, supply chain management, and toll collection. A survey found that respondents thought RFID could be used for inventory control, logistics, and library management. While RFID provides benefits like contactless reading and rewritable data, its costs remain higher than barcodes and standards are still being developed.

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
