The online titan, which has launched the justwalkout.com website to help advertise its tech to potential partners, said it has already signed “several” deals with unnamed retailers.

Customers in shops that use the technology will need to insert a payment card into a gated turnstile in order to enter rather than scanning an app, which shoppers are required to do in Amazon Go stores.

The turnstiles will display ‘Just Walk Out technology by Amazon’, but other branding will be controlled by the retailer.
