RFID technology uses radio waves to electronically identify objects. It consists of tags that carry data, readers that can interrogate tags, and software. There are active, semi-passive, and passive tags. Common applications include credit cards, toll collection, access control, and supply chain management. A survey found the most common potential applications were in document, library, and logistics management. Further development opportunities exist in medical and library uses. While RFID provides benefits over barcodes, limitations include potential high 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 Semi-passive Tags Passive Tags
•Use a battery •Contain built-in •Derive their power
•communicate over batteries to power from the field
distances of several the chip’s generated by the
meters circuitry, resist reader
interference and •without having an
circumvent a lack of active transmitter to
power from the transfer the
reader signal due to information stored
long distance.
•They are different
from active tags in
that they only
transmit data at the
time a response is
received

7. Applications
Frequency Appx. Read Range Data Speed Cost of Tags Application
Low Frequency (125kHz) <5cm Low High • Animal Identification
(passive) • Access Control
High Frequency (13.56 Mhz) 10 cm – 1m Low to Moderate Medium to Low • Smart Cards
(passive) • Payment (paywave)
Ultra High Frequency (433, 868-928 Mhz) 3m -7m Moderate to High Low • Logistics and Supply Chain
(passive) • Baggage Tracking
Microwave (2.45 & 5.8 Ghz) 10m -15m High High • Electronic toll collection (Autotoll)
(passive) • Container Tracking
20m – 40m
(active)

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
