Abstract
During a communication technique, an electronic device receives an audio signal from a remote electronic device, such as another electronic device that is proximate to the electronic device. This audio signal may include information that specifies an identifier. The electronic device may analyze the audio signal to extract the identifier, and may provide the identifier to a pre-defined location via a network, such as a web page on the Internet. In response to providing the identifier, the electronic device receives the operation from the pre-defined location via the network. For example, the operation may include an instruction to open a document (such as a web page) on the network.
