Interesting, I thought I'd tried that before and it didn't work because it wasn't near a reader. I'll try again, thanks!

I'd argue that it's still a slightly more complicated interaction than with TouchID, though, requiring a bit more mental preparation, perhaps.

As for TouchID: Yes, that's how it works. It's a more fluid action because typically you'll have added your thumb as the fingerprint, and it's easy to hold the phone with your thumb on the home button while holding it near the reader.
