发明名称 Tuneable radio-frequency identification tag reader and method of reading such a tag
摘要 A radio-frequency identification (RFID) system is provided that includes an RFID reader that is provided with a capacitor apparatus or circuit that may be used to tune the transmitter to a different frequency to improve communication with an RFID tag. The frequency may be changed by the capacitor circuit automatically providing a different capacitance output to the RFID reader. A tape drive reader and magnetic tape cartridge may be provided in combination with such an RFID system. A method is disclosed for reading a data packet stored on an RFID tag by a reader that can be adjusted by changing the capacitance provided to the RFID reader.
