An electronic device may generate a matrix code that includes information for performing an interactive activity related to content, combine the matrix code with the content, and transmit the combination of the matrix code and the content to a display device. Subsequently, the displayed matrix code may be captured by a matrix code reader in order to initiate performance of the interactive activity. In some implementations, the content may be a sporting event and capture of the matrix code may initiate performance of an activity corresponding to a fantasy sporting event league associated with the sporting event. In various implementations, the matrix code reader's initiation of performance of the interactive activity related to the content may utilize one or more other electronic devices located in a user location.
