Abstract
A device configured to receive a request, from a server, to provide frequency code information identifying a frequency code. The frequency code includes frequencies to be emitted by a broadcasting device that presents a first content. The device may generate a code based on the request. The device may receive a second content from the server. The device may store the second content and the code so that the second content is associated with the code. The device may generate the frequency code information based on the code. The device may provide the frequency code information for the frequency code to be emitted by the broadcasting device. The device may receive the code from a listening device that detected the frequency code emitted by the broadcasting device. The device may provide the second content associated with the code to the listening device.
