I know about all the security concerns people have with the fingerprint scanner, but are there any reasons why Apple don't make it public, so that all apps can choose to require the fingerprint rather than an ordinary password? I'm more than certain it could be done without compromising the users' personal data security (in this case, their fingerprint) more than it already is. Other apps would only send a request to touch ID whether or not the fingerprint is the correct one. There wouldn't be any harm done. My point is, if you sell a device with such a nifty feature, why not make it actually usable in more ways than just to unlock your phone? I have a banking app, an app where I store passwords, and Amazon and eBay aren't exactly shy to request a password each time I use the apps, either. So what are your thoughts on this? Just as an option. Or am I missing something?
