VIKEN, Sweden — A late-night rush to find baby food for his crying toddler spurred Robert Ilijason to build Sweden’s first unstaffed convenience store, The Daily Journal reports. The shop, naturally accessible 24/7, does not have a cashier. Customers sign up for the service and download an app, which they then use to unlock the door and scan their purchases. Payment is collected monthly via an invoice.

The store stocks c-store basics, such as bread, canned food, diapers, milk, snacks and sugar, but it doesn’t have tobacco or other high-theft items. “My ambition is to spread this idea to other villages and small towns,” Ilijason said.

He stocks the shelves and ensures everything’s neat and tidy. Six surveillance cameras record activity—and discourage shoplifting—in the 480-square-foot store. A text message alerts him if the door is open for longer than eight seconds or if a break-in is attempted.

His biggest challenge has been convincing some of the town’s older residents to conquer the technology involved in shopping at his store. But overall, customers have embraced the no-service convenience store, especially with its speedy checkout and lack of register lines.

Ilijason might install a credit-card reader as an alternative to the app to open the door, and perhaps hire a clerk to work for a few hours a day to assist customers having trouble with the technology, but for now, he’s content to allow his customers the freedom to shop on their own.
