Question: What is the difference between 1-Pass and 2-Pass?

This workflow provides a centralized perspective—typically a single scanner with pre-sorted content. It is a bit slower than the distributed 2-pass workflow, as each item is processed individually and at the time of scanning. It is used most often with single check to single stub sorted content or when read-and-key is needed.

This workflow indicates that the ability exists to ‘distribute’ work, whether it is from multiple scanners, or for multiple individuals performing various aspects of the work. This is the fastest method of processing as each item is processed on a separate server so the scanning device can read items as quickly as possible. Distributed workflow has the ability to manually perform verification and encoding.
