Automatic Identification Systems

Overview of RFID System What is RFID? oGeneric term for technologies that use radio waves to automatically identify things. oHappens with a “Digital Information” that is Store in a chip. oThat microchip has an attached antenna (the chip and the antenna together are called an RFID tag). oThe antenna enables the chip to transmit the serial number information to a reader. oThe reader converts the radio waves reflected back from the RFID tag into digital information that can then be processed.

Overview of RFID System (Tag) Types of Tags with respect to Storage Read only Read/Write Types of Tags with respect to Battery oPassive oActive oSemi-Active
