Imagine this: you’re shopping in a store and every employee has a small iPod touch and is capable of checking you out from anywhere in the store. Old Navy stores are reportedly using a form of Apple technology called ZipCheck. See the article here. Jim Hamm passes this info along, mentioning he used this checkout system recently at an Apple store. "It is a bit difficult to sign in the small space with no place to rest your hand. On the plus side, there's no waiting in line to checkout. I'm not sure what happens, though, if one wants to pay by cash?"
