iPad Screenshots


pDoc Signer is a complete standalone app for securely signing PDF documents on an Apple iPad running iOS 10 or later. pDoc Signer for iOS is unique among signature apps because, like handwritten pen-on-paper signatures, every pDoc Signer signature is distinguishable, unlike most other apps which “sign” with copies of signature images or text that can result in potential fraudulent use. Furthermore, each pDoc Signer signature is encrypted within the document at the instant of signing; pDoc Signer snapshots the document for every signature (not just once after all signatures) so that the contents of the document are preserved at the time of signing. To provide additional security, pDoc Signer signs PDF documents right on your iPad; the documents are not sent to a vendor’s server for signing. For valuable electronic transactions that must stand up to scrutiny, pDoc Signer’s biometric signatures are the gold standard for professional applications in business, finance, health care, law, real estate, etc.

With pDoc Signer you can: 

• Sign existing digital signature fields in PDF documents, using the PDF Digital Signature standard
• Create, place, and sign new digital signature fields in PDF documents without having to use expensive PDF document applications
• Fill in standard form fields: text boxes, check boxes, radio buttons, list boxes, and combo boxes
• Document signatures collected in pDoc Signer can be independently validated by Adobe Acrobat or Adobe Acrobat Reader to verify that the document has not been altered after it was signed. 

pDoc Signer, being a complete stand-alone app, does not require an Internet connection to capture and embed a signature, so in mobile applications where an Internet connection is not available, you can still fully complete the signature transactions, and then distribute signed documents at a later time. Purchasing a license for pDoc Signer for iOS is a one-time event; there are no recurring charges or usage charges.

Tech support is horrible

I bought this program a year and a half ago just about and now it is no longer working. I have been on the phone with this company trying to get help to figure out what I can do to get it running again but I am just getting a run around with this company. Every time I call I am told the developers are out to lunch and they will give me a call back or I need to request a call back from tech support that never calls back. Don’t waste your money on this program the company is horrible to deal with.
