Adobe’s .pdf document format is not only supported by Adobe’s own products, but also by a number of third-party products. Furthermore, there are generally available programming libraries and APIs for the development of individual solutions or for the integration of signing functions into existing products.
Note: Unless otherwise indicated, the following products are chargeable. Prices, purchase conditions and license conditions can be requested directly from the providers.
(a) Individual Signatures
Basically, the products of the Adobe Acrobat series (from version 6.0) enable the use of GLOBALTRUST. Depending on the version, the signature can also be designed and presented differently. The best experience so far has been with Adobe Acrobat Reader DC.
However, the product is only suitable for individual signatures. Each pdf document must be individually signed.

(b) Signing solutions for the desktop
Several companies offer special PDF singer solutions for the desktop. These products either allow the signature of a larger number of documents (mass signature) or work like a pdf printer and automatically add a signature to the pdf print output.

(c) server-based pdf signing solutions
A server-based solution is recommended for large amounts of documents, but also in companies with a large number of users. Instead of being sent directly via a mail server, the unsigned documents are sent to a proxy server, which carries out the signature process automatically and then sends the document.
For the user, this has the advantage of not being burdened with the signature process, the company has the security that all desired signatures will actually take place.
