A system for item and location information distribution utilizes a mobile device, at least one wireless information node, and a data server. The information node actively broadcasts a node identification (NID) via a wireless communication signal. When a user brings the mobile device within range of the wireless communication signal, the signal is received by the mobile device, allowing it to receive the NID. The mobile device then requests data related to the node from either the data server or a locally stored database generated from data previously retrieved from the data server. Software on the mobile device may then display headings and subheadings on the screen of the mobile device. The user may select a particular heading or subheading to display the content of the associated chapter or subchapter on the screen of the mobile device. |
