Abstract

The invention relates to a process for scanning a bar code which includes acquiring a first bar code scanning along a scanning line, identifying the family of the bar code, determining the width of at least one of the synchronism characters, calculating the estimated width of each character of the code being examined, based an the width of the synchronism character considered, determining a character following one of the synchronism characters by counting a number of m elements equal to the number of elements that make up each character in the family identified, determining the width of the following characters, checking whether the width of such following character differs from the estimated width of a lower quantity with respect to a prefixed tolerance. If the check gives a positive result, identifying the character and reiterating the steps until the other synchronism character has been reached. If the check gives a negative result, label the following character as an “undecodable character”.
