Abstract: A first device listens for a communication token across an audio bandwidth covering a transmit frequency one or more audio frequency broadcasting device. The first device receives at least one token broadcast from the one or more broadcasting devices. The first device demodulates and decodes each received token. One or more computing devices validates each decoded token. The first device determines, based on the validating, a broadcasting device of the broadcasting devices with which to establish a communications channel. The one or more computing devices generates a response token based on the token received from the determined device. The first device broadcasts the generated response token in a response band of the determined device. The determined device demodulates decodes, and validates the token broadcast from the first device. Upon determining the token broadcast from the first device valid, the first device and the determined device establish a wireless communication channel.

Abstract: A user device receives a service device identifier via a Wi-Fi scan at a location and transmits the received service device identifier to an management system via a network. If the management computing system receives multiple service device identifiers from the user computing device, the management computing system receives location data of the user computing device and signal strength data associated with each of the service device identifiers. The management system receives location data from the user computing device and determines a particular service device identifier from the multiple identified service device identifiers having a strongest signal strength where the user computing device location data also indicates the user computing device to be located within a geofence boundary associated with the service device. The management system transmits user account information to the selected service system computing device.

Abstract: A first computing device is configured to broadcast a first audio token comprising a first identifier over a first audio frequency channel, activate a first microphone component, and receive a first audio response token generated by a second computing device via the first audio frequency channel. A second computing device is configured to receive an input indicating a request to receive data, activate the second microphone component, receive the first audio token over the first audio frequency channel, receive one or more other audio tokens over one or more other audio frequency channels, determine that the received first audio token comprises a valid audio token, restrict the range of received audio inputs to comprise only the first audio frequency channel, generate the first audio response token, and communicate the first audio response token to the first computing device via the first audio frequency channel.

Abstract: An information system generates data, generates an audio token, associates the audio token with the data, and transmits the audio token along with the data to the account management system. The information system configures a broadcasting computing device to broadcast the audio token at a location. User computing devices at the location via an audio communication channel receive the broadcast token and retransmit the audio token to the account management system via a network. The account management system receives the audio token from a particular user computing device along with a request for data associated with the audio token, extracts the data associated with the audio token data, and transmits the data associated with the audio token to the particular user computing device.
