An engineering college in Bengaluru has hit upon a solution for the attendance devised not by the college management, but by the students themselves.Students of MVJ College of Engineering have designed a Bluetooth-based attendance-tracking system called ‘BT Proxy’. It helps to track a student’s whereabouts in the classroom, with the help of a low-energy Bluetooth module embedded in identity cards.As students walk into the classroom, the teacher will open an application on his or her smart phone and activate the ‘scan’ button. The app shows a message “discovery started”, and will detect all the signals sent out by identity card chips, which have been linked to a University Serial Number. The battery in the Bluetooth module is expected to run for an entire year.Gautam D. Hariharan, along with three of his friends Akhilesh Sridhar, NareinRao, and Jason Joy Manoj, developed this as a project during a competition last year.Many students resorted to malpractices by being proxies for their classmates and using imprints of fingerprints on dried glue, though the college has biometric attendance. They wanted to ensure that the entire attendance system is handled by a machine and there is very little manual intervention. All the ID cards will be scanned and registered on the app and the teachers would only have to do a headcount to ensure that none of the students brings the identity card of a friend. Presently, the software is in the testing phase. At present, the attendance of 60 second-year students in Electronics and Communication Department is being captured in this manner. The system will be implemented across the college for the 2018–19 academic years, depending on logistics and feedback from teachers and students.
