ABSTRACT:
The reading and decoding of two-dimensional bar codes in a bar code reader are simplified and field loading of different data character sets is enabled. Decoding of bar/space patterns of a bar code is simplified by deriving T-sequence data representative of the bar/space pattern and then processing a majority of the T-sequences directly into decoded values representative of the bar/space pattern. Dynamic loading of new data character sets fully or partially superseding a factory installed default character set correlation listing is enabled by use of loadable correlation listings keyed to foreign language characters, symbols, words or phrases relevant to particular applications. The loadable correlation listings can be encoded into a two-dimensional bar code and loaded via a reading of the bar code by the bar code reader.
