Interesting Comments at the end.

This would put a lot of people out of a job.

I wonder why it has to be an open store instead of a series of vending machines.

Now the 39-year-old IT specialist Robert Ilijason runs a 24-hour shop with no cashier.

Customers simply use their cellphones to unlock the door with a swipe of the finger and scan their purchases. All they need to do is to register for the service and download an app. They get charged for their purchases in a monthly invoice.

The shop has basics like milk, bread, sugar, canned food, diapers and other products that you expect to find in a small convenience store. It doesn't have tobacco or medical drugs because of the risk of theft. Alcohol cannot be sold in convenience stores in Sweden.

"My ambition is to spread this idea to other villages and small towns," said Ilijason. "It is incredible that no one has thought of his before."

He hopes the savings of having no staff will help bring back small stores to the countryside. In recent decades, such stores have been replaced by bigger supermarkets often many miles (kilometers) away.

Ilijason receives deliveries at the shop and stacks products on the shelves. Then he lets the customers do the rest.

He has installed six surveillance cameras to discourage shoplifting in the 480-square-foot (45-square-meter) store. Also, he is alerted by a text message if the front door stays open for longer than eight seconds or if someone tries to break it open.

I also wonder if someday people could order through the app and have a self-driving car deliver what they need to them.
