Sorry if this has been discussed previously, but I am really concerned about security if I activate Touch ID in my iPad. Shouldn't be? Apple says no but I am not convinced. Hackers these days are way too much capable to break into anything. Any insight on this issue? PS: by security I mean the possibility for someone to reverse engineer the actual fingerprint stored in the iPad. Apple says no way but I think it is a matter of time for this to happen.
