Abstract: Symbological communication operates to communicate information and data between mobile and electronic devices. Using certain information, an optical symbology is generated and displayed on the display screen of the mobile device. The optical symbology is read by an optical scanner coupled to the electronic device to read the optical symbology and decode the information contained therein. The electronic device uses the decoded information for different tasks, including providing authorized access to additional functionality of the electronic device by the user. After user interaction with the electronic device, it generates another optical symbology for on its display screen. The user of the mobile device would then capture the image of this optical symbology using the camera function of the mobile device. Applications operating on the mobile device decode all of a part of the additional information for local use or to communicate further to remote servers for additional use or tracking.
