The document discusses Radio Frequency Identification (RFID) technology, including its components, types of RFID tags, frequency and read ranges, and applications. It provides details on how RFID systems work and surveys results on industries where respondents think RFID can be applied, with logistics and supply chain management and library management being the most common responses. The document also discusses pros and cons of RFID compared to other identification technologies like barcodes.

3. * 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. * 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. * 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
