    Important Notice!

    The scanner RT840 outputs via Wiegand TTL interface, USB and RS232 interface. We have limited experience to guide the connection of RT840 with different brands of access control system since we don't have any terminal system here. If you mind our limited support on making the RT840 work with your terminal system, please consider twice before ordering a sample. The application of USB and RS232 will be easy as those normal scanner modules.
