Which type of technology can be used to monitor every product in a warehouse to enable real-time inventory tracking and updates?

Radio-frequency identification (RFID) technology is specifically designed for tracking products and inventory efficiently in real-time. RFID uses electromagnetic fields to automatically identify and track tags attached to objects. Each tag contains a unique identifier that a reader can scan from a distance, allowing for instantaneous updates to inventory levels without requiring physical contact with the items.

This technology significantly enhances inventory management by making it possible to monitor stock levels continuously and accurately, reducing the risk of human error that can occur with manual tracking methods. Consequently, businesses can optimize their supply chain operations and meet demand more effectively by always knowing the precise status of their inventory.

In contrast, the other options listed do not directly provide the same level of real-time tracking capabilities as RFID. Wide area networks (WAN) facilitate larger geographical data transmission but do not inherently include specific inventory tracking functions. Mobile utility applications can assist in various business functions but do not specifically focus on real-time inventory management. Operations management systems encompass broader processes in managing production and logistics but may not include the automated tracking capabilities that RFID offers.
