If a patient is unaware of an implanted RFID tag’s existence, or is unable to impart any information about it, what would be the logical next step when attempting to pair said tag to an effective and compatible interrogator?
You would need to determine what company manufactured the RFID transponder, as well as the standard it uses for the air-interface protocol at which the tags and readers communicate. You could then purchase a reader on the Internet that operates at the proper frequency and employs the correct standard. Perhaps the patient has a record of where he or she visited to get the transponder implanted, and that company might be able to provide the required information.
