RFID technology uses electromagnetic fields to automatically identify and track tags attached to objects. The main privacy threat posed by RFID is that it can be used to track people or consumer products without their knowledge or consent. This occurs because RFID tags can be read from a distance without the individual's awareness, potentially revealing their location or other personal information. This type of tracking can lead to significant privacy invasions. According to the IAPP, understanding and mitigating such privacy risks is essential for ensuring the responsible use of RFID technology in various applications.
