Smart  electronic  feedback  system  to  save  paper  and  time  using  RFID technology

Abstract:

There are many situations and occasions where we need to take the feedback especially in colleges we need to take the feedback of each and every faculty and we need to take the feedback of some event conducted by colleges. These feedbacks help us in evaluating one’s performance and to give better performance for next time. But in these procedures take lot of time and lot of paper usage is involved and we cannot keep these papers for long time. It is every human responsibility to follow “go green” and echo friendly systems as we know day by day how our environment getting polluted. One of the echo friendly systems is avoiding paper usage as much as possible. In this digital world this can be achieved easily with help of advancement in technologies. 

The main of this project is to reduce the time and manpower and eliminate the paper usage.

Now a day’s so many technologies are coming out to make our lives more comfort, user-friendly and luxurious. In this project we are replacing current paper based feedback system with our electronic based user friendly feedback system. This is a complete stand alone system in which we store all the feedbacks given by the students or participants in micro controller. 

The user has to show his RFID card and enter his feedback choice using respective switches and micro controller will receive this data and display on LCD then it will store in micro controller memory.

If anybody wants to give feedback more than one time this system will not allow them for more than one time
