Inside Walmart’s Tech Stack | Consumer Goods Technology

Walmart has been quietly building a sophisticated AI-driven infrastructure — and it’s shifting automation and intelligence closer to the store floor, directly affecting how products are stocked, promoted and purchased.

Here’s a look at some of the key tools and technologies Walmart is deploying across its ecosystem:

Digital Twin Technology

Walmart uses digital twin simulations — virtual replicas of stores and operations — to model supply chain scenarios, plan store layouts and improve product flow. These simulations help forecast demand more accurately and enable smarter inventory decisions in real time.

Computer Vision

Cameras and AI software monitor shelf conditions to detect out-of-stocks, misplaced items or planogram compliance issues. This data feeds directly into Walmart’s inventory systems to help associates restock more efficiently and improve product availability.

Augmented Reality for Associates

Store employees are using AR tools — often through handheld devices — to locate products, restock shelves and manage in-store tasks with greater precision.

RFID Tagging

The retailer has expanded its use of RFID (radio-frequency identification) tags on products to increase inventory visibility and speed up item tracking in stores and warehouses. This supports faster fulfillment and more accurate stock management. 

Walmart is also pairing RFID with AR tools, allowing employees to scan product codes and quickly see where items are located — whether on the sales floor, in the backroom or in transit.
