Optimize workflows and increase productivity

Our OCR feature allows incoming faxes to be seamlessly integrated into existing workflows. The text and barcode recognition feature is extremely accurate - up to 99 percent of the material contained in the fax is correctly recognized. This allows you to easily automate your fax process. There is no more re-keying of data or correcting mistyped entries. The OCR feature also permits extraction of key fields, like zip codes, customer number, or any other unique identifier so you can route the messages exactly where they need to go. If you have a need to archive and index your faxes for compliance, the OCR feature is a perfect fit.
