Attend Class vs Hello Vietnamese

Attend is a biometric and location-based attendance platform built for university students and lecturers. Instead of paper sheets, manual call-outs, or easily manipulated sign-in processes, Attend lets students mark their own attendance directly from their phones ; verified by their face and their location ; while giving lecturers a real-time, trusted record of who is present. How it works for students: 1. Open the app at the start of class 2. Verify your identity with a selfie 3. Your attendance is marked instantly and securely How it works for lecturers: 1. Start a session for your course 2. Watch attendance populate in real time 3. End the session when class is done Attend is built with fraud prevention at its core. Each student is tied to their own device. Location is verified at the point of marking. Proxy attendance (where one student marks attendance for another ) is detected and blocked automatically.
