If you want the bar code scanning to be independent of where the user is on the UI, then there is usually a serial port emulation available on USB. GET SERIAL PORT MAPPING is useful for this on Mac. You can then run serial comms in a separate process, which is handy if (for instance) the bar code readers are RF and being used at a distance from the computer (which also lets you run multiple scanners per computer). Or I’d guess that there must be some IP wifi based bar code scanners out there by now, so you could (presumably) simply do a TCP_Open.
