Walmart and Avery Dennison Pioneer RFID Technology for Fresh Food Categories

Breaking New Ground in Fresh Food Tracking

For years, RFID has been the backbone of inventory management in apparel, home goods, and electronics. Bringing the same precision to fresh food has been a tougher challenge. Cold air, condensation, and metal shelving interfere with standard tags, limiting their effectiveness in refrigerated cases.

Walmart’s collaboration with Avery Dennison solves that problem. Together, they developed a “first-of-its-kind” RFID-enabled label built to withstand the conditions of meat, deli, and bakery departments. The system allows store associates to count inventory more quickly, track freshness, and identify when to replenish or markdown items.

Christyn Keef, Walmart’s Vice President of Front End Transformation, said the goal is to reduce manual work so associates can focus more on customers. The technology gives them faster visibility into what is on hand and what needs attention.

Why It Matters for Walmart’s Operations

This development represents an important next step in Walmart’s journey toward full-store inventory visibility. In fresh food, even small improvements in accuracy can have significant impact.

1. More Reliable Stock Levels
   The new RFID tags improve read rates in cold cases, giving teams a clearer picture of what is actually available. That helps reduce out-of-stocks, which remain one of the biggest pain points in grocery.
2. Reduced Food Waste
   Each RFID label includes a digital use-by date, allowing associates to prioritize rotation and markdowns before products expire. Better visibility into expiration cycles means less unsold food and improved sustainability.
3. More Time for Customer Service
   By automating the most repetitive tasks like scanning or checking dates, Walmart is giving associates more time to focus on service, cleanliness, and presentation.
4. A Stronger Omnichannel Foundation
   RFID plays a critical role in linking store inventory with online fulfillment. As grocery pickup and delivery continue to grow, this technology provides the item-level data needed for accurate orders and substitutions.

What It Means for Walmart Suppliers

For suppliers serving Walmart’s fresh departments, this innovation signals a shift toward greater digital traceability. Walmart’s previous RFID mandates have focused on apparel, electronics, and home goods. With fresh categories now entering the mix, suppliers should anticipate new guidelines on tag placement, packaging materials, and data integration.

The Auburn University RFID Lab, which has collaborated with Walmart since 2022, is expected to support testing and certification to ensure tag performance in challenging environments. Suppliers who prepare early will be better positioned to align with Walmart’s evolving standards and benefit from the same operational gains.

Key Implementation Insights

• Performance in Cold and Moist Conditions: Avery Dennison’s label design addresses known RFID challenges related to condensation and metal shelving, ensuring consistent reads across fresh cases.
• Data and Systems Integration: RFID will generate richer item-level data that must be captured and shared effectively across supply chain systems.
• Cost vs. Return: While RFID tags remain costlier than barcodes, the gains in accuracy, speed, and waste reduction can offset that investment within months.
• Sustainability Considerations: With millions of tags in circulation, recyclability and environmental impact will become part of the conversation.

Looking Ahead

Walmart’s move into fresh-food RFID is more than a single pilot. It is another example of the retailer’s long-term commitment to improving visibility, efficiency, and sustainability across its stores. As this technology rolls out more broadly, it will reshape how suppliers manage freshness, reduce shrink, and plan production.

For Walmart suppliers and sellers, the message is clear: RFID is no longer just a backroom tool for apparel or electronics. It is becoming a standard for how modern retail manages the most perishable part of the business.
