This projects enables colleges to take accurate and honest attendance as it eliminates any and all human-manual entries. Every table including the teachers table will have a NFC tag present on it. When a teacher wants to start his/her class, he/she will only have to tap his/her phone onto the NFC tag which will then note down the time of class beginning and also notify students of the respective classroom that the class has began. The NFC chips are loaded with the unique URL of a student. When this student taps his/her phone on the NFC chip present on his table, it links to a data base where his/her sign-in/sign-out time is noted. The students are given a buffer of 8 minutes to get to class and sign in with their NFC tag. The web app will also be able to calculate when a student is late to class(>8 mins) and registers it as an offense. When a student commits 3 offences, 2% is deducted from his attendance percentage and their parents are notified. Students can view their attendance in real-time as it does not have to be manually entered by anyone, rather gets updated automatically via the web app.

For this project we used components such as NodeMCU and NFC chips which are both relatively cheap and thus provides to be a economic solution. NFC chips also do not require any kind of power supply as it is simply just a sticker with coils on it. NFC chips can practically be used forever as long as the coil on it remains intact, which can be achieved by adding a protective layered above the NFC tag. NFC tags are also very fast at their working.
