    Do you have reason to believe that this protocol is publicly documented. For all I know it could be proprietary. You could also be working at different UART settings than the card reader.
    Also what makes you think a UART is the correct tool for sending and receiving data to and from this device?

    I Googled Wiegand protocol and found several examples of how it works.

    Well that is a start. How about using a UART to send and receive data?
