    Yes, create a driver or a central application which will handle the actual
    scanning and then figure out how to distribute the data to the right
    application. That is, application A and application B both talk to
    application/driver C, which is the *only* one actually controlling or
    communicating with the scanner.

    You might be able to do this without code if each application can just take
    the data as though it was typed at the 'keyboard', rather than talking
    directly to the scanner control/library. That is, if you have a text field
    on one of our devices, and that field's application is in front and the
    field is focused, you can set things up so that the scan result is 'wedged'
    into the keyboard stream and the control gets data just as though it was
    typed there.
