Rfid

RFID is a technology that enables wireless data capture and transaction processing. There are two main areas of application, defined broadly as proximity (short range) and vicinity (long range) . Long range or vicinity applications can generally be described as track and trace applications, but the technology provides additional functionality and benefits for product authentication. Short range or proximity applications are typically access control applications. Radio Frequency Identification (RFID) is an emerging technology consisting of three key pieces: a tag, an interrogator (the reader) and a host system. The host computer manages the information flow, sending and receiving to and from the reader and tag. The reader contains a radio frequency module, a signal processing and microcontroller unit, a coupling element and the interface to a host system. There are many different kinds of readers on the market, such as desktop, hand-held, tunnel or gate / gantry style readers. The host system controls the data flow between the readers and tags. It can be as simple as a personal computer connected to the reader by an RS-232 serial cable.
