Abstract: A method executed by a local computing device communicatively coupled to a signature device includes launching a signature device control instance including a local web server. The control instance controls the signature device and receives signature data from the signature device, and listens to a localhost and a first port corresponding to a first URL. The method further includes retrieving, by a web browser executing on the local computing device, a web page from a remote server with a second URL. The web page includes a document indicating a context for a signature to be input by the signature device, and a cross-domain reference indicating the first URL. The method further includes, by the web browser, establishing a connection with the first port listened to by the control instance using the first URL; controlling the signature device; and receiving signature data from the signature device.
