Amazon is making its Just Walk Out cashierless technology available to other retailers.

The tech, which combines computer vision, sensor fusion and deep learning, detects what consumers remove or return from shelves, tallying them in a virtual cart. Purchases can be made with credit cards — mobile apps aren’t required — and consumers who need a receipt can retrieve one via email from a store kiosk.

Using the same credit card on future trips will automatically trigger an emailed receipt.

“Since launching Amazon Go years ago, many retailers have expressed an interest in offering similar checkout-free shopping experiences to their customers,” Amazon states on its website. “We’re excited to now offer the ability for retailers to leverage Just Walk Out technology from Amazon in their stores. By extending our technology to other retailers, more customers will delight in the Just Walk Out experience as they can take what they want and leave without stopping to check out.”

Installation of Just Walk Out can take as little as a few weeks once Amazon is provided store access. It will work with retailers on new store builds, or it will install the technology to existing operations “while minimizing impact on current operations.”

Amazon will also provide 24/7 phone and email support. Data collection will be limited to what’s needed to provide consumers with their receipt.

Although the company is making cashierless technology available, it doesn’t mean Amazon Go stores are becoming a franchise opportunity; Amazon notes specifically that retailers can’t open Amazon Go stores.
