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.
