Amazon Go Isn't The Only Game In Town When It Comes To Autonomous Retail

Not all cashierless stores are going to be near the nation's tech hubs like Amazon Go. In Indiana, for instance, convenience store chain Ricker's is rolling out what it calls "frictionless checkout technology" in its 56 locations.

The system is facilitated by an app called Skip that allows customers to scan items as they shop, and then pay by way of a linked credit card as they exit, without the assistance of a clerk.
