HTML signature application will not work with Chrome, Edge or Firefox
Our Signature and STU SDKs make use of ActiveX objects and the only Web browser which is still compatible with ActiveX is Internet Explorer.
Currently our Signature SDK HTML samples only work with IE. Alternatively you can either write a Java applet or use our SigCaptX cross-browser which is compatible with IE, Edge, Chrome and Firefox.
If you need to support Chrome and Firefox with our STU SDK we would recommend using our STU SigCaptX cross-browser component.
Please note that Safari is not currently supported.
