PeopleSoft Supply Chain Processing Document Capture Solutions

We have manual processes in place that satisfy audit requirements for multiple inventory processes (Express Issues, WO Issues, Receipts, consumables, etc) that require storage of different documents for respective processes. Documents include packing slips, issue tickets, pick plans, photos taken by the user, and other things depending on the process. We need to be able to store these documents electronically and include a digital signature pad where employees can "sign for" the product they are receiving. Is there anyone using this type of solution and can integrate it with PeopleSoft? We don't own Mobile Inventory so the signature capture would be coming from a USB signature pad or similar. Thanks for any help you may provide.
