For a prolonged period, RFID technology has been the cornerstone of location-tracking applications, owing to its RF-based communication capabilities. However, as advancements in technology progressed, the limitations of RFID in terms of security vulnerabilities and unidirectional communication have become more apparent. Although NFC technology, which is another RF-based communication method, has mitigated some of the security concerns and added bidirectional communication, it is still not a versatile solution for the location-tracking applications that are emerging.
