Tesco trials virtual grocery store at U.K. airport

 U.K. supermarket chain Tesco has begun testing out a new kind of grocery shopping -- going all-virtual in Gatwick airport.
The BBC reports that Tesco has been pondering a familiar problem -- you go on holiday, kids in tow, but the practicalities of the return home are still on your mind. Will there be food in the house when you get back, and if not, can you face a trip to the supermarket?
In response, Tesco has decided to install a "virtual grocery store" in the departure lounge of London's Gatwick airport.
The virtual store has four interactive screens, which users can swipe between by hand, each displaying approximately 80 products. If travelers want to buy an item, they will need to download a dedicated mobile app and then scan each product's bar code with their smartphone.
Once the virtual shopping trip has been completed, holidaymakers can choose to have their purchases delivered on the day they arrive back in the country.
