Touch ID

During today's quarterly financial conference call, Apple's Tim Cook fielded a question about using facilitate purchases. Cook said "It's clear there's a lot of opportunity there." The answer was as open-ended as the question, which is to say that Apple sees their Touch ID solution as simple and elegant, proven by engagement by iPhone 5s users in the App Store, and they see opportunity in the mobile payment space, and not necessarily tethered to Touch ID.

Still, Cook was predictably tight-lipped beyond that, and didn't have anything new to announce on that front. How do you guys think Apple could get involved with mobile payments? Might they finally pick up NFC in a device?
