OpenLimit SignatureService
OpenLimit SignatureService is the perfect all-in-one solution for enterprises wanting to sign large volumes of documents such as invoices or digital inboxes quickly and with full legal compliance.The server-based service signs your files automatically and in a matter of seconds after entering a PIN number just once at the card terminal.
Simply expand your process chain with the „Signature“ module
OpenLimit SignatureService can be conveniently adapted in line with generic enterprise processes. Standardised interfaces allow for seamless integration in existing systems. Running as a directory-based solution, OpenLimit SignatureService automatically loads the files from pre-defined folders, signs them, and then stores the legally compliant signed files where external applications can continue processing them.
Profit from a centralised solution
As a Windows service, OpenLimit SignatureService can be conveniently and securely controlled from the system management console. It has multi-client capability, is practically maintenance-free and requires very little hard disk space. As all kinds of signature cards and several card readers can be used at the same time, it is ideally suited as a centralised solution for enterprise groups with offices at different locations.
Send out a clear signal – with visible signatures
Decide for yourself where you want your signature to appear on the document. Choose an individual design for your signature, for example by incorporating your company logo in keeping with your corporate design. Or add your scanned hand-signature to your documents to make it clear that even in the digital world you have signed them personally.
