Supermarket launches trial virtual store in UK airport, ensures you've got fresh milk after your trip

UK supermarket Tesco has decided to bring its virtual supermarket screens (successfully trialled in South Korea last year) to Gatwick Airport. There's ten touchscreens in total, dotted around the departure lounge, with eager shoppers able to make a preemptive grocery strike with their smartphone. On-screen barcodes for around 80 items can be scanned by compatible -- that is, Android and iOS -- devices and added to your shopping basket. Following online payment, your bounty of food can then be assigned a delivery date up to three weeks in advance. The virtual shelves will stay up for two weeks; the UK retailer hasn't commented on further roll-out or extension plans. However, in an airport, during summer vacation, is probably the last place we'd muse on what we're going to eat on our eventual return. If you're wondering exactly how to shop with a four-foot touchscreen, Tesco walks you through it at the source link below.
