When I first read the headline, I wondered what kind of technological capabilities a company like Panera might have. However, seeing that they're going to be using Amazon One things make a lot more sense.

For me, a server-based biometric system for retail purchases is pretty much a non-starter. I wonder how many other retailers will be signing on with this particular system, and what benefits a server-based system brings to them.
