The main objective of this device is to take information about the attendance of students to lectures.

The manual process, signing in a signing sheet is not sustainable and accurate it also takes more time in this process as more the students the more time will be taken so due to these failures of this manual system we tend to see this alternative will make more successful and improves the efficiency of the system.

And also with the development of technology, our method tends to make the system updated with the technology.

The Device's physical look. sorry for the bad housing.
The web UI is ugly because I was built this in a rush :/

The system’s logical view as below;

Block diagram was drawn by using https://draw.io

HOW THIS SYSTEM WORK

What this system does is students will be given with an NFC card, every day before students participate in lectures, via NFC card their attendance will be marked as they swipe their card in our system, along with the time, the date they attend to the lecture.

WHY THIS DEVICE IS BETTER THAN TRADITIONAL MANUAL SYSTEM?

Students can cheat using the current system, by adding false signatures

Inefficient, it takes so much time to fill signatures in a signing sheet when the number of students gets increased.

ADVANTAGES OF THIS SYSTEM

Real-time information of the students

Reduces the time-wasting

Improves environmental quality because don’t use paper sheets or other things.

Increase the efficiency of the administration system

FUTURE WORK

The choice of the example provided for an NFC system implementation is only with regard to a university campus this is because it is most suitable and easy to start. However, the university and the education sector only make a small percentage of the commercial world of K.S.A. In the kingdom of Saudi Arabia it provides services for the whole this is a long-term aim. Dr. Mohammed Mohandes created the Hajj Pilgrim Tracking and Identification system this design system allows the pilgrim to identify him or herself at checkpoints, shop using e-Wallet, and download guidance maps from particular access points. Another good example is the Electronic Point of Sales terminal (EPOS) where customers pay by using NFC enabled phones. This system operates in two major parts. The first one NFC enabled payment terminals (PayPass terminal) provided by banks and the second part is towards the customer. The best example of this is the Google Wallet application. This system is developed by Google for mobile payment that allows its users to store credit cards, loyalty cards, gift cards. Payments can be made fast and convenient by simply tapping the phone on any Pay Pass enabled terminal at checkout.
