Just Walk Out is a recognition platform developed by Amazon to facilitate cashierless checkout experiences in retail environments. The technology first debuted in February 2020 with the opening of Amazon's first Amazon Go grocery store in Seattle, Washington.[1][2]

The technology works by using what its website describes as a multi-layered system of inputs,[3] including:

  1. A digital twin or 3D map of the store
  2. Integration of the product catalog
  3. Weight sensors for added precision for small, palmable items
  4. Overhead-mounted cameras

Implementation of the technology may vary by retailer, but at minimum, the process is as follows: a shopper enters the store, authenticates themselves in some form or another, and begins to select and take items off of store shelves. The items can be carried throughout the store by whatever means is most convenient for them, and AI-enabled cameras will recognize the shopper's exit as a trigger to charge the payment method associated with them.[3]

User privacy

[edit | edit source]

In a 2023 press release on the technology, Amazon explained that unlike Amazon One terminals, Just Walk Out was designed to operate without the need for collecting detailed biometric information on shoppers.[4] Rather than tracking the identity of a person themselves, a signature would be derived from their image and as they moved through the store, paired with a code generated upon entry into the store and deleted upon exit.

Nevertheless, like any other recognition platform, Just Walk Out necessitates the use of on-site devices to track and monitor the practices of a consumer using computer vision technology, in order to calculate what to charge them.[3] The normalization of such technology reinforces the cultural norm that treats privacy as a currency to be traded for convenience.

Business model

[edit | edit source]

Amazon's model for their Just Walk Out technology has seen frequent changes throughout its lifetime as its viability faces market challenges.

A month after its debut, in an effort to curb competition, Amazon began to offer the technology as a service to its rivals in the grocery space.[5][6] However, with competitors such as Grabango having beaten Amazon to the punch on what was already an experimental service, the few retailers showing interest in the technology were slow to outsource their checkout needs to Amazon's new alternative.[7]

In 2026, Amazon announced that it would be closing its in-person Amazon Go and Amazon Fresh grocery stores in a pivot toward an exclusively delivery-based grocery service, and with them, Just Walk Out would naturally no longer be used in these spaces.[8] While these changes coincided with the discontinuation of Amazon One, Amazon clarified that they would continue to market the service to third parties.[9] Since then, Just Walk Out has most often been implemented in stadiums and college campuses.[10][11][12][13]

Incidents

According to an April 2024 report by The Information, about 700 out of 1000 transactions made in 2022 through the Just Walk Out system had to be monitored by human contractors in India in order for the technology to operate reliably.[14] When Business Insider reached out to Amazon for comment, a spokesperson argued that the contractors were merely tasked with training the AI model that would perform the same task. They continued, "Associates may also validate a small minority of shopping visits where our computer vision technology cannot determine with complete confidence an individual's purchases."[15]

Two weeks after the initial report made headlines, Amazon published a press release touting the successes of their checkout-free technologies, which closed with a brief address of the incident[16] It read:

The erroneous reports that Just Walk Out technology relies on human reviewers watching from afar is untrue. Most AI systems, including the underlying ML models behind these technologies, are continuously improved by annotating synthetic (AI generated) and real shopping data. Our associates are responsible for this labeling and annotation step. Associates don’t watch live video of shoppers to generate receipts—that’s taken care of automatically by the computer vision algorithms. This is no different than any other AI system that places a high value on accuracy, where human reviewers are common.
