2. PROJECT OBJECTIVES

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
