Walmart rolls out digital shelf labels in U.S. stores as public reaction remains mixed

Walmart is rolling out digital shelf labels to replace traditional paper price tags, a change that some shoppers and lawmakers say could affect whether customers get fair pricing. The retailer said in March that about half of its stores have the technology, with the rest expected to adopt it within the next year. The rollout has prompted multiple lawmakers to file bills aimed at limiting the use of electronic labels for surveillance pricing or surge charging, including a New York State proposal that would prohibit electronic shelf labels in stores.

How paper price tags are updated

At a Walmart supercenter in Portage, Wisconsin, staff were installing digital shelf labels while much of the store still used paper tags. Employees described a process that can require extensive labor during price-change periods. Walmart employee Elizabeth Nigh said the store had nearly 1,200 prices to change across departments on Tuesday morning.

In Walmart’s system, prices are set by corporate headquarters in Bentonville, Arkansas, and store workers manage updates using an app on their devices. For paper labels, employees use small portable printers. Each four-foot section of the store has a code that employees scan to pull up the labels needed for that location. Workers remove the old label from its plastic sleeve and insert the new one.

When shelf pricing and register pricing differ, consumer protection laws generally require retailers to honor the lower price. Nigh noted that customers typically do not complain when they are rung up for less than expected, but price increases that have not yet appeared on shelves can create problems for shoppers and retailers.

Because the printer can handle up to 10 labels at once, larger runs are completed in batches. Nigh said categories with many variations—such as health and beauty—can require many different labels. She also noted that a typical Walmart supercenter carries around 120,000 products, and prices in some departments, including grocery, can change within days based on market conditions.

Digital shelf labels: setup, power, and pricing updates

In the toys and games section, Derek Gordon described installing digital shelf labels. He said it takes about six minutes to adapt a standard shelf section for electronic labels. He characterized the upfront work as modest, adding that it can save time later compared with paper labels.

Gordon said a rail clips onto the shelf face in a few clicks. The rail includes an integrated battery that can power the electronic labels for up to eight years. A Walmart spokesperson said the design is more economical than placing a battery in each individual label.

To ensure accuracy, Gordon scans the tag’s barcode with an app to confirm it is assigned to the correct product. As with paper tags, each four-foot section follows a specific plan that store employees must match.

Gordon said the digital labels are designed without sensors or cameras that could capture information about who is shopping. He said that means the labels cannot gather or transmit personal information about shoppers. He also referenced a New York State bill that would ban retailers from using shoppers’ personal information to adjust prices selectively.

Once set up, Gordon said employees tap a button after scanning, and the tags flicker on to display the prices stored in Walmart’s system. Walmart told him prices are set by the corporate office in Bentonville and pushed to stores overnight. Some social media videos have shown price changes appearing on electronic labels in the early hours before most stores open.

Store controls, durability, and error handling

Employees described operational differences between paper and digital labels. Gordon said the store uses alerts if a tag breaks or goes offline, notifying staff through the app. Another store manager, Zach Zeman, said he has authority to lower prices to stimulate sales, but cannot raise them above the range set by headquarters. He said there is an error alert if someone accidentally enters a number above the authorized price.

Zeman also said store prices generally match what is displayed on Walmart.com. Workers at another location said the digital tags are more durable than paper labels against shopping carts and other hazards, though they can still be damaged.

Finally, employees said the new tags are less likely to slide side to side on the rails, which they said helps keep displays aligned with the planned layout.
