The document discusses radio frequency identification (RFID) technology, including its components, types of RFID tags, and various applications. It then outlines the objectives, methodology, and initial results of a student project on music recognition using RFID, which included researching RFID online, conducting a survey, and an initial division of job roles among the students. The survey results showed that respondents believed RFID could be applied to inventory control, library management, logistics and supply chain management, and other industries.
4. 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
5. 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
6. 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
