Barcode ErrorsWhat if there is a printing error in a bar code?In any bar code, a printing error which cause multiple mutations in a barcode could lead to unintended character encodings and accidental transmission of the wrong information. Most of the time however, a printing (or scanning) problem will only cause one error. For some types of barcodes, a single error anywhere can end up looking like a different (and wrong) but valid, readable character. Other types of barcodes can be "self-checking". In a self-checking barcode, one single error can not lead to another valid character code. Simply, no two chracters codes are that similar, by design. In a self-checking barcode, errors can be detected but not automatically corrected. Back |
