interfacing with USB barcode scanner NOT as keyboard

[Ben Butler]

Hi Marc,

What about scanning and saving image / meta info to file system and then
having an Omnis timer that reads the files within the save directory and
pulling them into Omnis / save in DB?  Presumably you will be using some
client ware that came with the scanner / does the clientware have an Api
you can use to drive the scanner?

Kind regards

Ben
