Starbucks employees are being encouraged to test out a mobile-only payments store at the coffee company's headquarters in Seattle.

According to Reuters, the trial store will be used to ease bottlenecks during peak periods.

The Starbuck's headquarters serves over 5,000 employees through its two cafes and those coffee-drinkers are already encouraged to use the mobile ordering app.

Mobile orders within the headquarters will now be diverted to a new store where customers simply pick up their pre-ordered and pre-paid drinks from a window.

Starbucks is not the only company to test out new technology-driven stores on employees, at the end of last year, Amazon announced the launch of its Amazon Go stores in Seattle.

The technology giant created a grocery store without a checkout, which revolves completely around a consumer's mobile device. Shoppers scan their mobile device with the downloaded Amazon Go app as they walk into the store and the e-tailer's 'Just Walk Out' technology keeps track of which items they pick up. An array of proprietary technology – which Amazon is keeping pretty tight lipped about – automatically detects when products are taken from or returned to the shelves and keeps track of them in a virtual cart.

Customers simply walk out with their purchases and are charged via their Amazon account.
