Imagine the grocery store of the future. What would it look like? Some of you may be thinking of flying shopping carts, but many people will imagine improvements on the tedious checkout process. If you consider the process of shopping, the checkout is really one of the worst parts of the whole process.
Imagine: you drove to the store, you found your items, and then you must wait in line for potentially 15 minutes just for the privilege to pay for said items. Sounds more like a Soviet era bread line rather than an optimal customer experience.
