Abstract

The invention concerns a control unit (12), a control system (10) and a method for the checking of transactions carried out in a cash register (11). The control unit (12) has interfaces (27, 28) for connection to at least one cash register (11) and at least one receipt writer (13), and it is characterised in that it comprises at least one regulatory unit (21) in which encryption algorithms (22) are stored, which encryption algorithms (22) are used to generate a unique code based on transaction data (24) from the cash register (11), which unique code is sent to the receipt writer (13) to be printed onto the receipt. The authenticity of all receipts that are generated by the system can in this way be subsequently checked.

Claims

1. A control unit (12) with interfaces (27, 28) for connection to at least one cash register (11) and at least one receipt writer (13), characterised in that the control unit (12) comprises at least one regulatory unit (21) in which encryption algorithms (22) are stored, which encryption algorithms (22) are used to generate a unique code based on transaction data (24) from the cash register (11), which unique code is sent to the receipt writer (13) to be printed onto the receipt together with transaction data (24), whereby the authenticity of the receipt can be checked without the need to read the information that is stored in the control unit (12).

2. The control unit (12) according to claim 1, further comprising at least one internal storage unit (23) in which transaction data (24) from the cash register (11) is stored.

3. The control unit (12) according to claim 2, further comprising at least one further interface (29) for connection to an external computer or an external computer network.

4. The control unit (12) according to claim 1, which has been arranged with external protection (26), through its design, for example, as a sealed unit.

5. The control unit (12) according to claim 1, in which the regulatory unit (21) comprises some form of programmable logic device.

6. The control unit (12) according to claim 5, in which the regulatory unit (21) comprises an FPGA (field programmable gate array).

7. The control unit (12) according to claim 1, in which the encryption algorithm is an asymmetric encryption algorithm that uses keys.

8. The control unit (12) according to claim 7, in which the encryption algorithm is an RSA algorithm.

9. A control system (10) for checking transactions carried out in at least one cash register (11), which control system (10) comprises at least one cash register (11), at least one receipt writer (13), and at least one control unit (12), which control unit (12) is connected through interfaces (27, 28) to the said at least one cash register (11) and at least one receipt writer (13) characterised in that the control unit (12) comprises at least one regulatory unit (21) in which encryption algorithms (22) are stored, which encryption algorithms (22) are used to generate a unique code based on transaction data (24) from the cash register (11), which unique code is sent to the receipt writer (13) to be printed onto the receipt together with transaction data (24), whereby the authenticity of the receipt can be checked without the need to read the information that is stored in the control unit (12).

10. The control system (10) according to claim 9, in which the control unit (12) is a control unit further comprising at least one internal storage unit (23) in which transaction data (24) from the cash register (11) is stored.

11. A method for checking transactions carried out in a cash register (11) with the aid of a control unit (12), whereby the control unit (12) is connected through interfaces (27, 28) to at least one cash register (11) and at least one receipt writer (13) characterised in that the control unit (12) comprises at least one regulatory unit (21) in which encryption algorithms (22) are stored, whereby the method comprises the steps:

the transfer of transaction data (24) from the cash register (11) to the control unit (12) through the interface (27);

the use of the encryption algorithms (22) for encryption of transaction data (24) such that a unique code is generated;

the transfer of the unique code, together with transaction data (24), to the receipt writer (13) through the interface (28); and

the printing of a receipt in the receipt writer (13) comprising not only transaction data (24) but also the unique code, whereby the authenticity of the receipt can be checked without requiring reading of the information that is stored in the control unit (12).
