The exact locations of these stores aren't known, but it's likely one is coming to SF's Union Square, according to a report by The San Francisco Chronicle. As to what exactly makes these stores so exciting and futuristic: All you have to do is scan your phone on the way in, take whatever you want off the shelves -- food, drinks, other sundries -- and then leave. No making change, or eye contact with another human being. The store is canvased with cameras and sensors that keep track of what's leaving the premises, and you're automatically charged for whatever you've taken.
There are still employees at the store, however, with some preparing fresh food in a kitchen, plus a greeter and someone to check the IDs of those buying alcohol. Job listings are up for store manager positions at both locations, and we imagine that role will be a little different than managing a standard convenience store.
