Bar Code Scanner System

I am trying to determine the best way of doing this. We are wanting to add a bar code scanner in our shipping department that will intergrate with NAV. We are currently on NAV 2013. I guess my real questions would be what would be the best solution for this in order to keep track of inventory and make sure a order is filled properly? It doesnt necessarily have to integrate directly to NAV it could work in the sql back end if that is fine it would keep us from using another license in NAV. Please give me your thoughts on what product and the best way of going about it.
