The typical Walmart store has more than 120,000 products on the shelves with thousands of individual price tags. Every week, the company said, workers spend hours updating prices for new items and markdowns.

That’s changing soon, however. The nation’s largest retailer announced it is scrapping its traditional paper price tags for new high-tech electronic labels. Developed by Vusion Group, the new system  – known as Digital Shelf Labels or DSLs – will allow Walmart to update prices at the shelf level using a mobile app, reducing the need for workers to change tags by hand.

“DSLs allow us to update prices with a few clicks. A price change that used to take an associate two days to update now takes only minutes with the new DSL system. This efficiency means we can spend more time assisting customers and less time on repetitive tasks,” Daniela Boscan, Food & Consumable Team Lead, Hurst, Texas, said in a blog post.

DSL also has a “Stock to Light” feature so workers can flash an LED light on the shelf tag via their mobile device, signaling locations requiring attention and making it easier to identify locations when stocking. Also, a “Pick to Light” feature will guide workers directly to items needed for online orders, speeding up that process.

Walmart said DSLs will be installed at 2,300 of its 4,600 stores by 2026.
