I think you just need html and javascript (to check when the size of a
field is full, meaning the code was scaned).
I've done some barcode scaning stuff, and the only difference I see is that
you are using web.
Most of the barcode readers are like keyboards (like you said), so it would
be the same as if the user had typed.

Well, I've done barcoding stuff for a client which would have to type 6
digits, but depending of the volume of service, that helps.
Sorry about my english ;)
