Intergrating barcode scanners into your warehouse or production operations can give you realtime information as to the status of assemblies and inventories as they move thought your supply and production operations.
Development
Develop display forms and data handling logic that resides between your hardware barcode scanners and your inventory/production database(s).
Testing
Test your scanner logic before deployment with an integrated testing environment. A complete scanner solution can be developed without even having a real barcode scanner present.
Use
Use your real scanner the same as the integrated testing scanner.
