Figure 7.1: RFID Components
The reader decodes the data encoded in the tag’s integrated circuit (silicon chip) and the data is
passed to the host computer for processing.
The purpose of an RFID system is to enable data to be transmitted by a portable device, called a
tag, which is read by an RFID reader and processed according to the needs of a particular
application. The data transmitted by the tag may provide identification or location information,
or specifics about the product tagged, such as price, color, date of purchase, etc. RFID technology
has been used by thousands of companies for a decade or more. . RFID quickly gained attention
because of its ability to track moving objects. As the technology is refined, more pervasive - and
invasive - uses for RFID tags are in the works.
A typical RFID tag consists of a microchip attached to a radio antenna mounted on a substrate.
To retrieve the data stored on an RFID tag, you need a reader. A typical reader is a device that has
one or more antennas that emit radio waves and receive signals back from the tag. The reader
then passes the information in digital form to a computer system.
Task How to retrieve the data stored on RFID tag?
Did u know? The chip can store as much as 2 kilobytes of data.
7.4.2 Uses of RFID
RFID can be used in a variety of applications such as:
1. Access management
2. Tracking of goods and RFID in retail
3. Tracking of persons and animals
4. Toll collection and contactless payment
5. Machine readable travel documents
6. Smart dust (for massively distributed sensor networks)
7. Location-based services
8. Tracking Sports memorabilia to verify authenticity
9. Airport Baggage Tracking Logistics
Self Assessment
Fill in the blanks:
10. ................................ is the use of an object applied to or incorporated into a product, animal,
or person for the purpose of identification and tracking using radio waves.
