MyClass App helps save time in taking attendance inside a classroom, by making use of students' phones, AI (facial recognition) and Bluetooth technologies. Students give attendance using the app from their own (or peers') smart phones during a live session created by the teacher from his/her phone. The app identifies students using facial recognition, and also uses Bluetooth and/or a unique session code to ensure that the students are indeed present inside the classroom. The app can significantly save time of taking attendance for a classroom having a large number of students.
