Abstract
A graphically based encoded image, symbol or icon that can serve as a link from physical material or visual displays to electronic data to retrieve specific or general information. In one example, a graphic image is encoded with a value that is linked to a reference lookup table. For example, a numeric value may be encoded to form an encoded image by providing a primary image, such as a logo, and by positioning one or more secondary images or shapes in reference to the primary image, wherein the position of the secondary image relative to the primary image corresponds or relates to the numeric value. Generally, the encoded image may be in the form of any shape, figure or logo, and may be associated with, for example, an advertisement, web site, marketing program, corporate promotion, product promotion, sweepstakes, business cards, personal information, and other mediums for the exchange of information.
