Abstract: A segmented 2D matrix symbol may be formed by dividing data into a plurality of segments, separately encoding the plurality of segments as corresponding arrays of cells, and arranging the arrays of cells in an abutting relationship. The segmented symbol may be reproduced, for example by receiving a bitmap corresponding to the formed symbol followed by printing; by copying a printed symbol; or by scanning a printed symbol and printing a copy. The reproduced symbol may be scanned, and data from only decoded segments, for example audio data, may be output.

Abstract: A bar code symbol may include decode network response state configured to cause a bar code decoder to transmit a decode acknowledgement to a networked server computer corresponding to an acknowledgement address.
