Components of an RFID System
Radio frequency Identification (RFID) as the name implies uses radio frequency to exchange data between two entities for identification purpose. It is a wireless technology to collect information without any human interventions. An RFID system is basically an integrated combination of various components which work together for detection and identification of objects or persons. These are the components which are primarily responsible for working of any RFID system whether basic or complex. Although there can always be additional components associated with RFID systems like sensors etc. but the following are amongst the key components of these systems: A tag (sometimes called a transponder), which is composed of a semiconductor chip, an antenna, and sometimes a battery. An interrogator (sometimes called a reader or a read/write device), which is composed of an antenna, an RF electronics module, and a control electronics module. A controller (sometimes called a host), which most often Continue reading
