Abstract
A method for activating a user interface of a mobile terminal or device having an ISO14443 smart card attached in a ISO7816 reader, where the mobile device monitors the state of the inactive ISO7816 interface, the ISO14443 smart card changes the state of one or more of the ISO7816 contacts when it needs user interaction during contactless communication, and when a state change occurs that did not originate in the mobile device, an interrupt is generated that communicates to the mobile device that smart card requires its services.
