For what it is worth, I'm pretty sure that Amazon is already doing this at their Amazon Fresh drive-up stores. When you drive up, a sign lights up to say that your order is coming soon. The experience degrades a little bit if you arrive in a car they've never seen before -- a human stops by your window with a tablet to check you in.

That’s really cool!

Haven’t seen these yet, but Target has a pretty cool system that is app based. Easy to see how they could hook in cars.

Huh. It didn't even occur to me that they could also be using the app on my phone to do the same thing, and do it more accurately.
