Abstract: The present invention is embodied in a system for synchronizing a mobile device with video output by a video output device. In one embodiment, the system comprises a data reader, a remote control, and a router. The data reader is configured to be connected to a video output device for reading digital codes associated with video or audio signals output by the video output device. The remote control has a user input mechanism and is configured to transmit an activation signal to the data reader after activation of the user input mechanism. The router is configured to be connected to a wide area network for transmitting data from the data reader to a remote data server. The router is also configured to establish a local data connection between the data reader and a mobile device.

Abstract: A machine readable game card is provided which has a display surface and a readable surface, at least two terminals, and at least one path arranged on the readable surface between the two terminals, the path having an attribute of a predetermined value measured between the two terminals, and an image arranged on the display surface to which the predetermined value is associated. A reader for reading the machine readable game card is also provided which has a board with a surface, a plurality of pairs of terminals arranged on the surface, a connector, a plurality of circuits connecting each of said pairs of terminals to said connector, in which a pair of terminals on a machine readable game card contacts a pair of terminals on the reader when the machine readable game card is placed on the surface.
