Bar code reading terminal with video capturing mode

A method to train bar code reading terminal operators comprising the steps of:

• providing a bar code reading terminal;
• providing a bar code to be read by said bar code reading terminal;
• imaging said bar code using said bar code reading terminal;
• storing a plurality of images into a buffer memory;
• recalling each image of said plurality of images one at a time from said buffer memory;
• attempting to decode said each image of said plurality of images to extract bar code data;
• determining if said attempt to decode said bar code data was successful;
• if said attempt to decode said bar code data was unsuccessful, transferring at least a subset of said plurality of images subjected to decoding for later viewing, wherein an attempt to decode is determined to be unsuccessful if a decoding fails for N successive frames, wherein N>1, and wherein the N successive frames include a most recent frame of the N successive frames, and
• subjecting the at least a subset of said plurality of images to video viewing to evaluate an imaging technique employed by an operator of said bar code reading terminal, wherein the at least a subset of the plurality of images includes a frame taken before the most recent frame of the N successive frames.
