What technology uses RFID tags for product identification and monitoring?

The choice of Electronic Product Code (EPC) as the correct answer highlights its specific role in identifying and monitoring products through the use of RFID (Radio Frequency Identification) technology. The EPC is designed to uniquely identify a particular item, providing a way to track items across supply chains and inventory systems. RFID tags equipped with an EPC can transmit data wirelessly, allowing for efficient monitoring and management of products without the need for line-of-sight scanning, as is required with barcodes.

In contrast, other technologies mentioned, such as barcode systems and QR codes, utilize visual scanning methods that rely on optical recognition. These methods work well within their context but do not leverage the advantages of RFID technology, such as the ability to read multiple tags simultaneously or at greater distances. While asset tracking systems could potentially use RFID technology, they are a broader category that can incorporate various tracking methods, including RFID and barcodes. This distinction makes the EPC the most fitting answer specifically in the context of RFID tags.
