if I understand it clearly in API doc, currently there is no way how to display PDF (operate methodPDFLoad from SignoPAD-API) like through WebSocket Pad Server?

Will be there this option in future versions?

Thanks for answer,

We are always working on new features and improvements. Currently, you need to render the PDF document by yourself and load the images to the pad using TOKEN_CMD_API_DISPLAY_SET_IMAGE.

WebSocket Pad Server removed from MENU

Why was WebSocked Pad Server removed from MENU Software? Users have trouble finding it.

Hello, we changed the name from the product. This was done because of the user feedback for the old name. We will add the old name for a limited time with a hint for the new name. Thank you for your comment!

Hi, unfortunately not.



Is this compatible with Evolis Sig100 tablet? We need to capture the client's signature and sign (image) a pdf document from a web interface and then save the signed pdf document.

Is the API sign or the PAD_API sign necessary?

all our software is compatible with the Evolis signature pads!

Hello, we support originally purchased signature pads only. These pads must be purchased direct from us or from one of our partners/resellers. We don't support the distribution via unknown third parties on eBay.

Hello, this issue should be fixed with the current version here on this website. Please ensure that you use min 1.0.16.


Do you have more information about TOKEN_PARAM_SIGNATURE_SIGN_DATA? The WebSocket pad server indicates it is a encrypted, compressed, biometric data format.

Is it possible unencrypt/uncompress and view the actual biometric details?

Hi, inside our signoAPI we have libs to decrypt and view the signature. We provide an analyze tool for the biometrics as well. As an alternative you can use TOKEN_CMD_SIGNATURE_POINT

WebSocket Pad Server for Linux


Is there an alternative for WebSocket Pad Server in Linux environments?

Hello, the question is not related to the operating system. Even more to the web-browser technology: How to get access to a hardware through a web-browser? NPAPI or ActiveX is an alternative, but discontinued from the browser manufacturer. More here:
