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
