Abstract

A vending-type machine for goods and/or services, and a method of operating the same. The machine has a computer that is connected via a data communication line with a central computer located in a central office. In order, despite the absence of an intermediate cash box for bills received during an interrupted payment process, to be able to protect against fraudulent refunds for equivalent values on vouchers issued by such machines, a plain language as well as machine-readable coded data entry is printed on the voucher, with this data entry, in addition to the value of the bill, also containing the location indication of the particular machine, and the actual date and time in seconds. This data entry is entered in a data-protected memory of the machine, and is entered via the data communication line in a data-protected memory of the central computer. Upon redemption of the voucher at the central office, the coded data entry is read and this is compared with the data stored in the memory of the central computer prior to paying out the equivalent value.

Claims

1. In a method of operating a vending-type machine for goods and/or services, with said machine having a computer that is connected via a data communication line with a central computer located in a central office, with said machine further including a bill-checking mechanism, bill-conveying mechanism for conveying a bill or bank note to a cash box, as well as a printer, which, upon interruption of a payment procedure after the transfer of at least one bill into said cash box, prints out a voucher for the equivalent value of the received bills as proof of entitlement for receiving a refund in said central office, the improvement including the steps of:

printing on said voucher a plain language as well as machine-readable coded data entry that in addition to the value of said bill, also includes the location indication of said machine, and the actual machine operation date and time in seconds;

entering said data entry in a data-protected memory of said machine and also entering said data entry, via said data communication line, in a data-protected memory of said central computer; and

upon presentation of said voucher for redemption at said central office, reading said coded data entry on said voucher in a data reader and comparing this read data with said data stored in said memory of said central computer, and paying out said equivalent value when said comparison has determined that the data entry on said voucher is the same as the data stored in said memory.

2. A method according to claim 1, which includes the step, after transfer of said data entry to said data-protected memory of said central computer, of printing out said data entry via said printer.

3. A method according to claim 1, which includes the step, after transfer of said data entry, via said data communication line, to said memory of said central computer is completed, of clearing said data entry in said memory of said machine.

4. A method according to claim 1, in which said data entry additionally includes a recognition mark of a particular machine operator.

5. A method according to claim 1, which includes the steps of:

limiting the maximum value of said voucher; and

issuing at least one additional voucher to take care of a value for received bills that exceeds said maximum value.

6. A method according to claim 1, in which refund of money in said central office is effected with the aid of an automated money return machine.
