To securely sign PDF documents, you need software. We offer different products and programming interfaces depending on the operating system and application areas.
If you want to sign PDF documents on your PC, we recommend one of our signature pads and our signature software signoSign/2. The signoSign/2 application also works with Windows tablet PCs, such as Microsoft Surface. A pad is then of course not necessary.
Our products for PDF signatures ensure document integrity (protection against changes) and make the authenticity of the signer verifiable.
There are also other products available for mobile operating systems or integration purposes. You will find an overview under the menu item Software solutions.
