Use Barcode to Access Unique ID

Hi,

Is there a way we could use the barcode scanner widget to populate fields based on the unique number scanned? 

(i.e. the barcode scanner will scan a serial number, and the Description and Control Number will automatically populate)

My question is, can we use the barcode to access the unique identifier? (and then to populate the form...)

Thank you!
