When you are at an event, using Data Harvesting's Mobile Event Capture from the Student CRM, you want to prevent students using the Home button to close down the app and do something else.
The last thing you need is for a student to close the app and browse to something, well shall I just say 'something less desirable' for the next visitor to your stand to see.
OK, you have 2 choices: a) Cover the iPad's home button (many lockable iPad stands do this) b) Lock the iPad's home button (if your stand does not cover it, or if you don't use a stand).
