Radio Frequency Identification (RFID) is a technology that uses electromagnetic fields to automatically identify and track tags attached to inventory items. RFID systems improve inventory visibility and accuracy by enabling real-time tracking without manual scanning, reducing human error and labor costs. RFID is particularly useful in complex supply chains with high volume or high-value goods. It enhances inventory optimization by providing detailed insights into stock movement, location, and status, enabling better demand forecasting, faster order fulfillment, and improved loss prevention. Implementing RFID requires upfront investment but can yield significant efficiency gains.
