Code Reliability

Code reliability describes the possibility of incorrect interpretation during scanning and evaluation of the code. Most barcodes include a self-test function, meaning the number of barcode symbols (barcode symbol) per encoded character is checked. The number of symbols (e. g. bars and spaces (space)) is the same for each encoded character included in the barcode. The use of a check digit which is appended to the information characters allows for the recognition of substitution errors. Some barcode types require the use of a check digit.
