Walmart's Shelf-Label Tools Log 5 Million Flashes Ahead of Holiday Rollout

Walmart's Shop to Light feature has logged more than 5 million customer flashes since its limited rollout this summer, as the retailer prepares to deploy three new digital shelf-label tools chainwide before the holiday season.

The features — Shop to Light for shoppers, plus Pick to Light and Stock to Light for store associates — all run on the same light-up electronic shelf labels. Greg Cathey, Walmart's senior vice president of digital transformation, said the trio will reach all stores in time for the company's peak shopping period.

"This is a use case that customers have asked us for, associates have asked us for," Cathey said. "It gives them time back, and I think if you look at a lot of what we're trying to do, it's all around convenience and being able to help associates and customers free up that time to invest it where they want."

How do the three tools work?

Shop to Light lets a customer pull up a product on the Walmart app, walk to the correct aisle and trigger a flash on the digital shelf label to pinpoint the item. Pick to Light and Stock to Light give associates the same capability to fill digital orders and restock shelves.

Walmart stores carry roughly 120,000 items, a scale that makes fast product location a daily operational problem. Cathey said the company views the new features as "a big win" for time savings heading into the holidays.

How far has the digital shelf rollout gone?

More than 4,300 Walmart stores already use digital shelf labels, with installation expected to wrap across the chain by year's end. Roughly 90% of sections inside those stores now carry the electronic labels, according to Cathey.

Prices on the labels change overnight, when customers are not in the store. The system has human oversight to ensure it has "robust governance" and does not make mistakes, Cathey said.

Why does the holiday timing matter?

Convenience and speed — especially in delivery and pickup — have become central to Walmart's sales strategy. E-commerce revenue has continued to grow, but the August earnings report stirred investor concern over comparable sales and the revenue outlook, sending the stock lower.

The chain faces its highest-traffic weeks of the year as the rollout completes. Cathey said the new features will be especially important as Walmart heads into the busy holiday season.

Where does this fit in the broader AI push?

The shelf-label features are one slice of a larger technology overhaul. Walmart has rolled out an AI shopping agent, automated parts of its supply chain, deployed radio frequency identification tags, and is preparing for agentic commerce. It has also spent billions modernizing store locations.

On the most recent earnings call, CEO John Furner told investors the company is already seeing significant returns on its technology and AI investments. "We believe AI will improve nearly every part of our business by making shopping better, and our associates' work easier," Furner said.

Cathey framed the strategy in human terms. "We are people-led, tech-powered," he said. "But the way we look at it is AI as a way to help associates do their job and free up time to allow them to invest in what they love to do most, which is spend more time with customers and their fellow associates."

What are the pricing and privacy concerns?

Digital shelf labels and the AI push have drawn backlash over fears of dynamic pricing and surveillance. Several state legislatures, including New Jersey, have passed measures restricting the labels. Walmart said the feature is live in all of its New Jersey stores and called the state policy an "overreaction, as digital shelf labels are not a tool for surveillance pricing and are simply a modern way to display prices."

In an open letter last week, Furner said the company is continuing to "price the product, not the person." He added: "Your income, shopping history, urgency or what we think you could pay won't change the price."

What's next for the store-versus-online debate?

Cathey, who has held his role for nearly a year, said his top priority on taking the position was to accelerate technology while preserving human oversight. "We don't look at it as technology for technology's sake," he said. "So we always have a human in the loop, and we're very focused on human judgment and their ability to make decisions."

Walmart has separately pushed drone delivery, with options in select states including Texas and Florida promising delivery in as fast as 30 minutes. The service has faced its own privacy scrutiny.

Cathey said the new label features reflect a larger conclusion for the company: "It's not one or the other anymore. It's both. We don't look at it as a store or an e-commerce fulfillment. They're actually one and the same."

The three features, companywide by the holidays, will test whether that blended vision can survive the busiest shopping weeks of the year — and whether the labeling technology can hold up against a growing list of state-level pricing restrictions.
