Abstract
An automatically-activated laser scanning 2-D bar code symbol reading system for use in a work environment, wherein a hand-supportable 2-D bar code symbol reader is arranged in two-way communication with a base station operably connected to a host system. The 2-D bar code symbol reader includes (i) a bar code symbol data detector for automatically detecting each line of said 2-D bar code symbol, and producing a line of scan data for buffering in a buffer memory, (ii) an audible data capture buffering indicator for automatically generating audible sounds as each line of bar code symbol data is captured and buffered in said buffer memory, and (iii) a decode processor for automatically decode processing an entire set of scan data collected in said buffer memory and corresponding to a scanned 2-D bar code symbol, and generating a symbol character data string representative of said read 2-D bar code symbol.
