Abstract
Document information is encoded in a graphic symbol applied to the document. The symbol is read to retrieve the document information which is then translated into a humanly discernible form different from that appearing on the document. In one embodiment of the invention, a symbol is applied to sheet music and encoded with the music score printed thereon. The symbol can then be read to produce an audio rendition of the music score. Also, a symbol can be applied to a printed text page and text encoded. The symbol can then be read to produce a vocal reading of the text. Other applications using encoded symbols to uniquely identify or memorialize persons named on credit cards and business cards are disclosed.
