What specific technology has Walmart required its top 100 suppliers to use for product cases?

Walmart's requirement for its top 100 suppliers to use RFID (Radio-Frequency Identification) technology for product cases reflects the company's strategic initiative to enhance supply chain efficiency and inventory management. RFID technology allows for automatic identification and tracking of inventory without the need for direct line-of-sight scanning, as is required with traditional barcode scanning.

By implementing RFID, Walmart can achieve real-time visibility of its inventory across the supply chain, significantly reducing out-of-stock situations and improving the accuracy of inventory data. This technology enhances the overall efficiency of logistics operations, as it facilitates faster check-ins and check-outs at distribution centers and stores, leading to streamlined processes. The use of RFID also helps to minimize human error and labor costs associated with manually scanning barcodes.

This initiative underscores Walmart's commitment to leveraging advanced technologies to optimize its supply chain and ultimately ensure better product availability for customers. The decision to focus on RFID is indicative of the company's strategic approach to maintaining its competitive edge in the retail market.
