Part Instance update from barcode reader

We are looking at a system where a As-Operated structure is set up in Windchill using Part Instances with a barcode attribute. We then want to be able to conduct an audit of the site using a barcode reader and automate update of the As-Operated structure from the barcode reader.

Has anybody setup something similar to this? I'm looking at whether it is possible and, if so, what sort of effort was involved to do it.
