Increased speed with added security

The barcode-reading technology of the Relay inserter accelerates the mailing process. Plus, it adds an extra layer of security to ensure that the right documents are sent to the right person. The advanced camera reads instructions that are contained in the barcode to automate variablepage mail. This eliminates the need to manually sort documents by page count. Your mail will be processed with superior accuracy without sacrificing speed. Pitney Bowes document enrichment software options make adding security simple. Our SaaS or on-premise software adds barcodes directly to your existing documents without the need to involve your IT department. You can take advantage of additional value by being able to correct address data, qualify your mail for postal discounts, enhance formatting and even create and send digital versions of your documents.
