Project Objectives

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

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

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
