How do you Detect Fake GPS Usage in App Inventor for Attendance Validation?

MIT App Inventor Help

Hello everyone,
I’m developing an attendance application using MIT App Inventor. I want to ensure the user is using a real location and not manipulating it with apps like Fake GPS.

My questions are:

  1. Is it possible to detect Fake GPS usage directly in App Inventor?
  2. If not, are there workarounds (e.g., checking location provider, speed, accuracy)?

My goal is to allow attendance only when the user’s location is authentic.

Thank you in advance!

Two factor authentication ? Along with GPS, provide a daily (or shorter) qr code for attendees to scan.
