Radio Frequency Identification (RFID) technology is primarily used for what purpose?

Radio Frequency Identification (RFID) technology is primarily utilized to track and identify objects without the need for physical contact. This capability is achieved through RFID tags, which can store information and communicate wirelessly with RFID readers using radio waves. This process allows for quick and efficient identification of items, whether they are products in a retail environment, assets in a warehouse, or even livestock on a farm.

The advantage of RFID technology lies in its ability to provide real-time visibility and automate tracking processes, which can enhance operational efficiency across various industries. By using RFID, large volumes of items can be scanned simultaneously, reducing the time and effort required for inventory management and monitoring.

The other options do not align with the primary function of RFID technology. Encrypting sensitive information pertains to protecting data confidentiality, which is unrelated to RFID's purpose, as RFID focuses on identification and tracking. Enhancing network security typically involves technologies and practices focused on securing data transfer and communication, not tracking objects. Transmitting audio and video signals relates to multimedia technologies rather than RFID, which specializes in object identification and tracking.
