Just finished a really cool implementation for a large commercial property management company.

The sheet runs lookups to their Term Store, and auto-builds the managed metadata columns as 2D barcode elements. Here is a sample sheet:
So, using PSI:Capture, you can then auto-extract the barcode elements and map them to columns. It even supports multi-level term sets. Below is the end result in SharePoint:
I will get a video demo posted of this Scanning, Barcodes and SharePoint demo soon.
