Description
Wacom sign pro PDF is the complete professional solution for securely signing and annotating PDF documents in a paperless workflow.

When you use sign pro PDF as your document reader you will also have tools for:

- Electronic handwritten signatures
- Freehand annotations
- Sticky note texts
- Text highlight, underline and strikethrough

PDF files that require signatures or annotations may be transferred to a device through various means. For example, you might receive an email with a PDF file attachment which requires your signature. You can open the file attachment and view its contents directly in sign pro PDF. To sign the document, you can select the signature tool, select a position in the document and then sign using your finger, capacitive stylus or Wacom active stylus. You can then send your email reply with the signed PDF document attached.
Your signed document can be viewed in any PDF reader and your signature will appear exactly as you created it. In addition, sign pro PDF follows industry-standard PDF electronic signature standards so any changes to the document will result in signatures being shown as invalid.
The stylus used to sign determines the type of signature created:

- ‘touch’ signatures created using your finger or capacitive stylus do not contain biometric data
- ‘biometric’ signatures created using a Wacom active stylus contain full biometric data including pen pressure

Poor app. Can't easily add date Scam - ask to pay for each new signs.
★☆☆☆☆ Alan Duncan · Jul 6, 2018
Total waste of time. Installed on Note 8, made all the right noises but failed to work as expected. Just a waste of my time thinking I was doing something wrong.
★★☆☆☆ A Google user · Oct 21, 2018
It requires a new signature each time you sign. No signature library.
