Abstract
The invention relates to a system of automatic correction where certain errors are accepted while others are recognized as errors. This applies specifically to non-machine readable inputs or to optical character recognition when reading or transcribing codes. When entering certain characters, this system would allow certain similar character combinations and number of errors from that set while still maintaining integrity of identification codes.
