Selected items of part information which together form information to be registered, transferred and stored, are registered in that the corresponding bar codes are read by means of a bar code reader (4) and are entered into a computer (6). The computer is caused to print the inputted bar codes and the corresponding items of part information in clear on a sheet of paper (8).
