What is Electronic Signature

Every day, each office workflow is going paperless. Implementing electronic signature is one way to make your work easier, more secure, and more efficient.

Wacom provides signature capturing devices and solutions for handwritten signatures. An electronic signature is used to assign an electronic document to its originator, thereby assuring authorship. A qualified signature also safeguards a document’s authenticity (is the document actually from whom it says it is?) and integrity (has the document been changed at any time during the transmission process?).

Electronic Handwritten Signature for Customer-Facing Applications

If you are looking for a solution to develop your own electronic signature system, we are here to help.

With over 30 years of experience making the digital world feel like the real world, Wacom takes the user experience seriously.

Wacom provides a natural, smooth, and responsive digital ink and digital pen experience which is legally binding and it feels like writing and signing on paper. Using Wacom SDKs and signature pads enables your solution to provide a high customer experience and to view text and images clearly on the screen, especially after hundreds of thousands of transactions. Wacom SDKs and signature pads are the most robust, reliable, and durable capture devices available which delivers the lowest total cost of ownership (TCO).

What you can do with SDKs

This is the place where you can find technical information for SDKs. Wacom SDKs open new opportunities for your solution and application.

Signature SDK

Signature SDK is for STU series, pen displays, pen tablets, and mobile devices. This SDK includes the tools necessary for enabling applications to capture biometric handwritten signatures. This SDK requires minimal effort to integrate, and automatically renders digital ink, displays dialog boxes, and captures full biometric signature data.

STU SDK is for signature pads; STU series. This SDK requires more coding effort than the signature SDK, but allows unrestricted access to the data which can be stored in any suitable format. Applications can upload graphical images to the pad display and record the pen movement, including timing and pressure information. It is available for C#, Delphi, HTML and Java.
