Real Digital Signatures on Android with qPDF Notes 2.2

April 12, 2012 - PRLog -- Android device users finally have the ability to validate and apply true digital signatures to PDF documents with the new 2.2 release of qPDF Notes, Qoppa Software’s PDF Android app.  Also in this release are improved editing of annotations properties, and additional user interface improvements.  

qPDF Notes 2.2 is the only Android PDF tool with the ability to apply true digital signatures directly from an Android device.   The app allows the user to choose which digital signing certification to use: create self signed certificates, or import digital certificates issued by a certificate authority such as Verisign or Thawte.  Digital certificates are PKCS files with a .p12 or .pfx filename extension.  

qPDF Notes also enables the digital signature's appearance to be fully customized by adding a handwritten signature (through a finger gesture) and by overlaying an image such as a company logo.

“Qoppa’s suite of tools to validate and apply electronic signatures on PDF documents is now extended to mobile devices.   Our users have been signing documents on Windows, Mac and Linux with our desktop tool PDF Studio for years. They can now sign PDF documents on the go with qPDF Notes.“ says Qoppa President Gerald Holmann.

Qoppa Software also makes these new features available in the latest version of qPDF Toolkit for Android developers to integrate PDF features into their own apps.
