Wacom STU-SDK

The STU SDK is the most basic version of available Wacom SDKs and is designed to integrate Wacom’s STU signature pads into Windows applications. It requires the most development effort, but due to its basic functionality it also gives the developer the freedom to fully customize their application the way they need it. The Low Level SDK collects raw pen data and allows images to be loaded to the screen. The Low Level SDK does not require a license key and is free of charge. It supports Windows and Linux operating systems.

Wacom Signature SDK

The Signature SDK – Signature Component makes integrating signature capture very easy with minimal development work. With this SDK it’s possible to collect, store and display forensic handwritten signatures. It includes data-hashing functions which securely bind the signature to signed content, such as a document. The Signature Component can be used to collect signatures on any of Wacom’s signature pads or graphics tablets. A license key is required to deploy this SDK and it will not be free of charge / will imply a license fee. The Signature SDK – Wizard Component is based on the Signature Component and gives greater flexibility in the interaction with Wacom signature pads. It provides the ability to easily implement soft controls, including push buttons, check boxes and numeric key-pads. A license key is required to deploy this SDK and it will not be free of charge / will imply a license fee. The component interfaces are designed to be simple to use and to ensure that all the information necessary for a legally binding signature on an electronic document are collected and stored. The data include the full record of the pen movement during signing, the pen position and pressure within time, as well as forensic information such as the ID of the computer and pad being used. Signatures collected with the Signature SDK components can subsequently be examined using Wacom’s analysis tool SignatureScope. Wacom Signature Scope is only available for Forensic Document Examiners and visualizes the dynamic Signature data which can help to proof the authenticity of a handwritten electronic signature.

Signature SDK for Windows

Our signature SDK includes the tools necessary for enabling applications to capture biometric handwritten signatures using any of Wacom's signature pads, pen tablets or pen displays. This SDK requires minimal effort to integrate, and automatically renders digital ink, displays dialog boxes, and captures full biometric signature data. It is available for a range of programming languages including C, C++, HMTL/JavaScript, Delphi, C#, VB.NET and Java. Signatures are stored in a format that can later be analyzed by qualified authorities, such as Forensic Document Examiners, using our Signature Scope application.

Signature SDK for Android

This SDK provides the same functionality as the signature SDK for Windows, but works on pen-equipped Android devices. Java is currently the only supported language for this SDK.

STU SDK (aka Low Level SDK)

The STU SDK is a software development kit that allows applications to capture pen data using any Wacom STU-series signature pad. 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, which is needed to collect biometric handwritten signature data. It is available for C, C++, HMTL/JavaScript, Delphi, C#, VB.NET and Java.
