Bluetooth-Based Smart Attendance System

Recently, there have been many attempts to develop offline classrooms to enhance educational efficiency. One of these attempts is the introduction of IT systems in colleges to replace existing attendance management systems. Existing systems authenticate students’ lecture attendance by simply using login data, but this has inherent issues involving substitute attendance and not being able to identify whether students are really present in the lecture room. To solve these problems, we have implemented a Smart Attendance System using Bluetooth, which is supported by most smartphones. This system consists of a student’s smartphone app, a lecture room terminal (referred to as Raspberry Pi hereafter), and a management web page. This Smart Attendance System is used to manage attendance and related academic administration by using Bluetooth, HTTP, and RESTful (web services that follows the representational state transfer) technologies.
