From using RFID devices in student identification cards to track attendance at university classes to card-based customer loyalty programs, controversies around the use of RFID center on the balance between privacy and information. "RFID, and electronic storage and transmission of information more broadly, often evokes concerns about breaches of privacy. In practice, the technology often replaces tracking methods prone to security lapses," Rebecca Walberg writes in a report published in The Vancouver Sun. While some experts suggests RFID is not a threat to privacy, given that programs such as customer rewards require user consent, others, like Prof. Yeona Jang of McGill University, caution, "there are privacy issues that need to be addressed accordingly, as technology advances."
