Barcode recognition is the most efficient way to capture index data printed on documents. Some documents already have key information in barcode format on them. In many cases adding a barcode to a document is as simple as changing or adding a font. Adding barcodes to new documents is preferable as all the index data is on the document at the time it is created and in a format that can be read with near 100% accuracy.
As an alternative to placing barcodes on the individual documents, it is possible to print out a barcode cover page and place it on the file before it is scanned. The Simple Coversheet application was designed to make this easy by providing a simple interface for selecting index values and printing a standard coversheet that contains these values in barcode format.
Barcode recognition can also be useful when you have documents with a variable number of pages that will all receive the same index values. If it is not possible to generate an indexed coversheet for these at the time they are created, a generic barcode coversheet can be used to separate the scanned images into multi-page files, one for each document. A second process can then be used to index these images, one file at a time instead of one page at a time, greatly increasing output.
