The control unit 6 compares the PROXI card data with the data stored in the PROXI card ROM 9. If the data matches or does not match, the USB access device provides appropriate sound and light indications. From the real-time clock 11, the control unit 6 receives information about the time the card was applied and transmits data to the ROM of history 10. Also, the ROM of history 10 contains information about the parameters of the card and information about the coincidence or mismatch of the card with the identifier. If necessary, the computer can read the required information from the ROM of history 10.
