i picked up an iPad Mini to use with Square for employees to take payments. I'm not too concerned with them using the iPad for other things, but thought if possible I'd lock them out of everything besides Square.app. Is this still not really possible with iOS? I'm also thinking I'd like to use the ipad to keep records for each game, I run a paintball field. I'd like to have an app, maybe just Numbers, that employees can enter all the info. But, what I'd like to do is have it sync with my iPad without things from my iPad syncing with that one. Is there something that will do that? Or do I just need to maybe setup an email account on it they can use to send the spreadsheet after each game?
