<p>The invention provides a human error preventing system wherein a worker is provided with a work slip indicating data as to the work to be performed in a form readable by the worker and with a work instruction bar code representing the work data. The worker performs the work and is provided with a result representing bar code representing the result of work performed by the worker with reference to the work slip. The worker uses a bar code reader to read the result representing bar code and the work instruction bar code. The reading signals from the bar code reader are transferred to a work control computer. The work control computer collates the work instruction bar code and result representing bar code reading signals and the worker is notified whether the result of collation is appropriate.</p> |
