The need of using a Radio Frequency Identification (RFID) System

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