What is "radio-frequency identification" (RFID) used for?

• A. To monitor employee attendance
• B. To track and identify items
• C. To secure online transactions
• D. To manage customer relationships

Answer: (B)

Radio-frequency identification (RFID) is a technology used primarily for tracking and identifying items. This system employs radio waves to transfer data between a reader and a tag attached to an object. RFID tags can hold information about the item and can be read from a distance, which makes it highly efficient for inventory management, supply chain operations, and asset tracking. In industries such as retail, logistics, and manufacturing, RFID technology allows businesses to monitor the movement of goods, manage stock levels in real-time, and streamline their operations by automating the logistics process. This capability reduces manual errors associated with traditional identification methods, such as barcode scanning, and enhances overall efficiency in material management. The other options—monitoring employee attendance, securing online transactions, and managing customer relationships—while they may utilize various technologies, are not the primary functions of RFID, which is specifically designed for item tracking and identification.
