There is a trend right now in SharePoint Scanning and Capture, and I really see organization leveraging MFPs and copiers to provide scanning to the masses. As you can well image, this could be an absolute nightmare without the use of document capture software that can provide the ability to standardize the posting of information to Document Libraries.
The trend right now is the use of barcode cover sheets and/or OMR routing sheets. The routing sheets seem to be the hot method at this point in time, because they provide the user the ability to have a pre-printed stack near the copier, and when they need to scan, they grab a sheet and a sharpie, color in the boxes that determine the metadata, and then scan. Below is a link to an example OMR sheet for a law firm. Note that the check boxes are mapped to document library, and also are utilized to create file folder and file naming.
I will go over some barcode sheet examples in a later post.
