Most barcode scanners can be programmed to send a 'preamble' string before the data that you scan. This is how I differentiate input sources in my barcode app.
Another trick is to ensure you reset the focus to a text field after you are done processing the input.

If the scanner comes in via serial cable, then it is a set of data that your program needs to gather and deal with. In that case, the data is separate. For us, it's just a fast alternate keyboard that is used to enter specific information into one specific field. Once that information is entered, a script processes the bar code data and the cursor gets moved to another field where keyboard entries are done. Then when that set of data is saved, a new blank page gets created and the cursor goes into the field for the bar code data, and the scan process starts over.
