Auto sense and encode printer system for multiple classes of RFID tags

摘要

An RFID printer system and method interrogates or accesses RFID tags automatically using a user-defined sequence of settings for different RFID tags or classes. Once a successful interrogation is completed, the settings are saved and the saved settings are used for interrogation on the next tag. Each new roll of tags/labels,starts interrogation with the first of the settings. Consequently, the printer system can read from and write to tags of more than one class without hardware or software changes in the printer.
