This project named “RFID BASED ATTENDANCE SYSTEM” is based on RFID as the name suggests. In this project our aim is to make a note of every employee entering the room and also to calculate the amount of time person resides in room. Before company used to enter the data in register and it was bit clumsy.  Company then thought of going for barcode but barcode was not that much durable? Barcode requires continuous line of sight, low data capacity, cannot be rewritten etc. due to this problems barcode cannot be used. So RFID is the solution of all problems. It is quite easy to work with. Tags con be reconfigured if read/write tags are used. Range can be improved by using high frequency reader. It can also add to security. By programming many other facilities can be added.
