Abstract

A method for combining decoded scan fragments of a bar code symbol composed of a delimited plurality of bar code elements representing an ordered sequence of data characters. The method includes scanning the symbol along a first scan path that includes a delimiter to obtain a first sequence of data characters; scanning the symbol along a second scan path that includes another delimiter to obtain a second sequence of data characters; comparing the predetermined length to the lengths of the first and second sequences of data characters; and based on the comparison combining the first and second sequences to produce the ordered sequence of data characters.
