    Thank you so much.



  • @mookai1973 that RFID reader spits out a string of characters, it does not act like an HID (more like someone typing fast on a keyboard). If the computers cursor is directed into a text entry box you may be able to identify different cards, but this would be a very dodgy setup (if you move the cursor it will not work).

    Some RFID readers like this also offer the ability to add extra keystrokes and commands to the string they output, this may help make a reliable system. Most can also output serial or telnet, either of those protocols would be better to work with.

     @Fred Thank you so much for reply and then I will try to check RFID for serial and test it.
