This Store Doesn't Have Any Cashiers

A convenience store in Viken, Sweden relies on technology, and customers' good faith, to pay for items. There are no cashiers -- instead, shoppers use their phones to scan each item's barcode and receive an invoice later on.

Robert Ilijason, the store's owner, had the idea when he ran out of baby food one night and had to drive miles to find an open store. He wanted a 24/7 convenience store in his town, but since hiring an around-the-clock staff was expensive, he opened a members-only store. The store has been so successful that Ilijason is planning to open more.
