Methods, systems, and apparatus, including computer programs encoded on computer storage medium for implementing the advertisement of device status information. In one aspect, configuration data for the second device is obtained, where the configuration data indicating a current operating mode of the second device or a user-specified configuration of the second device. The stored radio transmitter identifier is accessed from the one or more data storage devices. A first advertisement that indicates the radio transmitter address and the radio transmitter identifier is generated. A second advertisement is generated that indicates the radio transmitter address and an encoding of the configuration data for the second device. Using the radio transmitter, a series of advertisements that includes at least the first advertisement and the second advertisement is broadcasted.

The present disclosure provides systems, methods, and computer program products for transmitting data to computing devices via audio communication channels. A computer-implemented method performed by one or more processing devices may include, for example, providing an audio token to a broadcasting device for broadcast via an audio communication channel, receiving the audio token from a user computing device, the audio token being received from the user computing device based on an audio broadcast of the audio token by the broadcasting device via the audio communication channel, and obtaining, in response to determining data that is associated with the received audio token, approval to process a payment transaction by at least in part transmitting the data to the user computing device.

Introduced here are approaches to transferring relevant information from a first electronic device (also called a “source electronic device”) that is presently outputting an interfacing signal that is detectable by a second electronic device (also called a “recipient electronic device”) via modification of the interfacing signal. Such modification causes the relevant information to be appended to the interfacing signal and then transferred to the recipient electronic device. This can be accomplished by superimposing another signal that is representative of the relevant information onto the interfacing signal. Thus, the relevant information can be transferred from the source electronic device to the recipient electronic device by superimposing a signal onto the interfacing signal that is output by the source electronic device.

An information providing system provides delivery information using identification information of an object equipped with a wireless communication function. The information providing system includes a registering unit that registers in advance first link information linking the identification information of the object to the delivery information; a generating unit that generates second link information linking the identification information of the object to delivery information different from the delivery information of the first link information, based on the identification information of the object and identification information of a plurality of information terminals, acquired by communication with the information terminals, which can communicate with the object; and an information providing unit that delivers the delivery information linked by the second link information.

A device, system, and method may provide an audio component of a multimedia stream playing on a video monitor to one or more wireless computing devices. The extracted audio component of the multimedia content may be packetized into data packets and broadcast via a network such that the data packets can be received by the wireless computing devices and the audio component can be played by the wireless computing devices in synchronization with the visual component playing on the video monitor.

Embodiments are provided for syncing multiple electronic devices for collective audio playback. According to certain aspects, a master device connects (218) to a slave device via a wireless connection. The master device calculates (224) a network latency via a series of network latency pings with the slave device and sends (225) the network latency to the slave device. Further, the master devices sends (232) a portion of an audio file as well as a timing instruction including a system time to the slave device. The master device initiates (234) playback of the portion of the audio file and the slave devices initiates (236) playback of the portion of the audio file according to the timing instruction and a calculated system clock offset value.
