PURPOSE:To reduce the complexity of management and to prevent the generation of mismanagement by managing a used slip by slip numbers previously printed on the slip. CONSTITUTION:Slip numbers 3, 4 previously printed on slip paper 10 are read out, and when the slip numbers 3, 4 are normally read out, data relating to a transaction are printed out on the slip paper 10. The data relating to the transaction are managed by the read slip numbers 3, 4. In addition to unused slip paper, used slip paper 10 is also managed by the slip numbers 3, 4 previously printed on the paper 10. Consequently, the complexity of management can be reduced and the generation of mismanagement can be prevented. |
