Apparatus and associated methods may relate to a coded contact information exchange made between source and target electronic devices. In an exemplary embodiment, the coding scheme may be a non-industry standard coding scheme. In an illustrative example, one or more contact fields comprising user contact information are encoded in a barcode format for exchange between the devices. In some examples, the barcode may be transmitted over a non-optical communications link. In other examples, the encoded barcode may be transmitted over an optical communications link. In some examples, the barcode may comprise a two-dimensional barcode. In some examples, the source and target devices may comprise handheld devices, such as mobile phones.

System for the Exchange of Optically-Encoded Information

A method and apparatus for generating and accessing a coded centralized dynamic database via a computer or computer network with the latest product and service information for use by retail establishments, manufacturing facilities, and product distributors.

Method and Apparatus to Provide Centralized Information Database for Retailers, Manufacturers, and Distributors in Target Industries and Markets

A composite signal having frequencies within a sonic first frequency bandwidth may be received from a communication media on a receiver. The composite signal may include an audio base signal and at least one code signal. The code signal may be encoded with a code. The composite signal may be output on a speaker, the speaker converting the composite signal into sound. While outputting the composite signal, a signal processing device may detect the output sound corresponding to the code signal. The code may be determined from the detected output sound corresponding to the code signal. Data associated with the code may be retrieved from a data storage device that is internal to or remote from the signal processing device. The retrieved data, when displayed on a display device, may be selected by a user. The signal processing device may automatically send signal-processing-device-specific data to a remote server when the code is determined or when the user inputs an input using the displayed code-associated data.

Coded acoustic signal communication with separate code-associated data communication

Interactive data communication with acoustic signal communication

A system (10) for distributing barcode information. The system (10) includes a plurality of terminal systems (16 a to 16 n) in communication with a database system (12). The database system (12) includes a database (22) of item information related to a plurality of item identifiers representative of barcode information. At least one of the terminal systems (16 a) requests barcode information from the database system (12). The request including an item identifier representative of a barcode, and in response, the database system (12) transmits barcode information associated with the requested item identifier to the at least one terminal system (16 a).
