Patent number: 8495617Abstract: Disclosed are an interworking system between a user terminal and a smart card for executing a widget and a method thereof. The interworking system is configured to enable the user terminal to manage the download setup information for a widget UI (user interface) program installed in the smart card. The user terminal is able to download widget UI data to be updated from a program provision server based on the download setup information even if there is no additional request from the smart card. Therefore, the system is able to prevent periodic communication between the user terminal and the smart card when updating the widget UI program.Type: GrantFiled: July 29, 2009Date of Patent: July 23, 2013Assignee: SK Planet Co., Ltd.Inventors: Jin Tae Kim, Eun Su Jung, Hoo Jong Kim
