One such application is RFID. RFID stands for Radio Frequency Identification. There are many use cases being practiced in day to day lives of RFID such as in transportation, shopping malls, agriculture, factories, health-care and many more. Another application is a smart attendance system. The current traditional attendance system has many limitations which can be overcome with the help of RFID based attendance systems. This system consists of RFID scanners also called tags and RFID readers to offer more efficient and accurate information gathering of the students. This paper focuses on developing an RFID based Attendance System using microcontroller, some sensors, RFID tags, readers and other basic electrical components. RFID based attendance system provides the most modern approach to track user check-in and checkout status. Keywords:-RFID, tags, readers, students, attendance, system, IOE. INTRODUCTION In educational institutions, the traditional technique of manual attendance is often inconvenient and time-consuming. However, RFID technology can help to solve this difficulty. Radio Frequency Identification (RFID) is a form of automatic identification that allows data to be retrieved from or stored on RFID tags without the need for physical touch. When an RFID chip is queried by a reader device, a radio transmitter produces a coded identification number. Some RFID tags can be inspected from a distance of several metres and beyond the reader's line of sight. The use of bulk reading allows for practically concurrent tag analysis. This little type is used to identify clients' merchandise, and it's even implanted in dogs. This RFID-based attendance system includes a storage device that records the student's unique identification number, as well as a user-friendly interface for commercial reasons. The main goal is to create a system that will take authorized individuals' attendance, record the data together with time and date, and store it in a database. Each user would be given their own RFID tag, and a record of their usage would be kept. RFID is growing popularity these days, with applications in industries, offices, transportation, agriculture, and other areas. A tag can be attached to any object and used to keep track of goods, assets, persons, and other information. It can be attached to cars, laptop computers, books, cell phones, and other items, for example. This shows how RFID technology can help different institutions with efficiency, and comfort at a very cheap cost. This method is both quick and easy. When a student enters or exits a class or campus,
