A comparative study on radio frequency identification system and its various applications

<span>The radio frequency identification (RFID), is a wireless technology system that used for identifying an individual or objects through the means of waves transfer information from electronic tag, called RFID tag. consists two main components interrogator and transponder. The Interrogator, which reader, usually transmits receives signal while transponder attached to object. In system, reader interrogates tags. This tag generates interrogation, communicates with tags been registered in system. likewise has receiver captures reply generated decodes signal. reflects tag's content. Each employee student unique identity, card (ID) assigned single ID card, recorded, database research reviews some recent designs implementation internet things (IoT) attendance systems using concept analysis found very advanced automatic institution, organization, university it provides higher performance accuracy than traditional paper-based employees students normally sign. use enables authorities, management evade documents damages such as misplacement, tear, even got lost. A combination model needed will confirm security, better performance, consistency system.</span>
