At the beginning of the year Amazon launched an experimental Go store in Seattle that featured no cashiers, payment tills, and a skeleton staff that simply stocked the shelves.

Now the tech giant is aiming to expand its convenience store plans, with a second location opening up in Seattle later this year.

According to GeekWire, the new Amazon Go store is located across town from the original, and the company plans to have it up and running sometime in Q3 this year, although a precise date is not mentioned.

The cashier-less concept is certainly an interesting one, and it appears as if customers are keen on the idea too, with sensors embedded in the shelves and NFC-enabled technology tracking all the items picked up and taken out of the store.

From there, the customer’s gets billed via the Amazon Go app, which is a godsend for those who don’t want to have any human interactions during their food shopping experience.

The additional implication of this experiment is the potential effect it could have Whole Foods, which is owned by Amazon, with the cashier-less system possibly being integrated into the chain’s current model.

With Microsoft also looking to go the till-free route for its own convenience store, this could be the next battleground for big tech companies to fight it out over.
