Is the barcode reader connected on the same machine running web2py?
If yes you just need to create a function in the controller that you
can call and reads the value and puts it in the session or
where you need.
something like this (it will be more complex depending on hw):
def barcoderead:
barfile = file('<barcode device>', 'r')
code = barfile.read() # blocks here until data arrives
barfile.close()
return dict(barcode=code)
You can callit as a normal url:
http://your.host.name/barcodeapplication/barcodecontroller/barcoderead
so you
can use anything you like for instance ajax
hope that helps!
