"First self-service store selling jeans opened in Seoul, Korea last October."
From the outside of the store, we cannot see anything inside, that is how the exterior looks like. Inside the store, it is very similar to other fashion stores, but no staff. Customers can come in with their credit card check-in and purchase their jeans via the prepared tablet inside after they try in the fitting room.
More self-service store will come in 2019 due to high minimum wage. It has increased around 30% last 2 years, reaching USD7.50 per hour this year. Big franchise like Lotteria and McDonald already start deploying Self-order Kiosk.
