This particular technology would mean you need not worry about remembering a passcode to unlock your iPhone 5S, and it also doubles up as a means to authenticate purchases that are made from iTunes. It remains to be seen whether Apple will eventually make the decision to open up this technology to developers down the road, so I guess we will just have to play the wait and see game. If you were a developer and gained access to the Touch ID technology, what would you do with it? I suppose other than for verification purposes, it might not do much at all, but then again I am not a developer who has some money making ideas, right?
