Description

 The invention relates to methods for monitoring and collecting information, including about unauthorized access to a cash register, to systems including one or more remote cash registers interacting with a central information processing device (computer), and can be applied at various points of trade enterprises and public services, and also used by tax authorities.

 Up to 70% of all tax payments to the Russian budget are accounted for by trade and service enterprises, therefore, any change in the quality of control over cash flow in these areas of the economy has the most direct impact on the state financial policy.

 The main means of control are cash registers.

 A known method of collecting information about cash receipts by printing reports on a receipt tape. Revenue information is stored in the fiscal memory (FP) of the cash register. The fiscal memory unit is a non-volatile information storage medium long-term storage device (memory), which is part of the cash register and is designed to register reporting summary information on a receipt tape. Access to information must be protected programmatically and with an appropriate password. To obtain this information, the tax inspector must enter his identification code (password) into the cash register and perform the necessary actions in accordance with the individual algorithm of each cash register. For further processing of information, the tax inspector must manually enter the data received on the receipt tape into a computer device.

 The disadvantage of this method is the low productivity and the likelihood of errors during manual information through a computer keyboard. The tax inspector needs to know the operation algorithm of various types of cash registers and the corresponding passwords for access to their operating modes. In this invention, access and transfer of information about cash receipts is achieved using portable non-volatile storage device, which has its own individual identification code, as well as communication channels for input and output information. Revenue data is accumulated in non-volatile memory included in the FP unit 5. Through the communication channel, revenue information is sent to a computer device and after processing it receives revenue and tax data in a convenient form.

 A known method of controlling the revenue of electronic cash registers, based on the registration of information and its accumulation by means of a fiscal memory unit with the exception of the possibility of changing, entering information into a computer device for subsequent information processing.

 Also known is a revenue control system comprising an electronic cash register that includes a microcomputer, a fiscal memory unit containing a non-volatile memory device, RAM and ROM, and a computer device for processing information.

 Known method and device are described in patent JP, N 64-6519, class. G 07 G 1/12, 1989.

 The technical result of the invention is to increase the labor productivity of tax inspectors, reduce the requirements for their qualifications, eliminate errors in processing information.

 In addition, the proposed solution allows you to automate the process of information retrieval and its processing.

 The technical result is achieved by the fact that in the method of controlling the revenue of electronic cash registers, based on the registration of information and its accumulation by means of a fiscal memory unit with the exception of the possibility of changes, entering information into a computer device for subsequent processing of information, the identification code of the non-volatile portable storage device is sent through the channel communication to the fiscal memory unit of the corresponding electronic cash register, in which it is compared with a predetermined and other if they coincide, they transmit information via a communication channel to a non-volatile portable storage device, while the fact of access is recorded and this information is also transmitted, the information transferred from the fiscal memory blocks of electronic devices is accumulated in an independent portable storage device, and information stored in non-volatile portable storage device, and enter into a computer device for processing the received data.

 In addition, in the revenue control system of an electronic cash register, consisting of an electronic cash register, including a microcomputer, a fiscal memory unit containing non-volatile memory, random access memory and read-only memory, a computer device for processing information in the fiscal memory block a microcontroller is introduced with the ability to compare the identification code of a non-volatile portable storage device with a given input - the output of which is connected to the output-input of a non-volatile memory device, a non-volatile portable memory device connected via a communication channel with a microcontroller of the fiscal memory unit and a communication line to a computer device is introduced into the system.

 In FIG. 1 shows a functional diagram of the system; in FIG. 2 is a flow chart of an electronic cash register operation algorithm and a computer device operation algorithm.

 The system contains electronic cash registers 1, each of which includes a microcomputer 10, a fixed memory unit (FP) 5, containing a microcontroller 4 and non-volatile storage device 6, random access memory and permanent storage device 12 and 11, a computer device 7, a communication channel 3 and a communication line for inputting and outputting information 13 associated with non-volatile portable storage device 2.

 The computer device 7 comprises a circuit 8 for comparing codes and a data processing unit 9.

 The system that implements the method works as follows.

 Data (information) of the cash proceeds from the storage device (memory) 6 in the FP unit 5 of the electronic cash register 1 through the communication channel 3 is supplied to a portable non-volatile memory device (memory) 2 in which it is stored. In the computer device 7, the information is received practically without the participation of the operator through the communication line 13 using a portable non-volatile memory 2 having its own identification code. When registering an electronic cash register for the first time, the identification code of a portable non-volatile memory 2 (tax inspector code) is automatically entered into its memory through communication channel 3. This information is stored in the memory of the non-volatile memory 6 included in the FP unit 5. Information about the revenue is accumulated in the memory 6, which is controlled by the microcontroller 4, also included in the FP unit 5.

 When taking evidence of cash proceeds, the tax inspector sends his identification code to the FP 5 block through a portable non-volatile memory 2. Microcontroller 4 compares it with a code originally stored in the memory of an electronic cash register. If the codes match, the data is transferred from memory 6 to memory 2. Having one portable non-volatile memory 2, you can get revenue data from 400 cash registers.

 The information accumulated in the memory 2 from numerous electronic cash registers is transmitted via a communication line 13 to a computer device 7. After comparing the identification codes in the code comparison scheme 8 of the computer device 7, the information is sent to the data processing unit 9 and as a result, data on revenue and taxes are obtained in a convenient form. With each operation of accessing the memory of the memory 6, the microcontroller 4 fixes the memory reading process and this information, together with the data of the FP 5 block, is recorded in the non-volatility memory of the portable memory 2.

 In case of unauthorized access to the cash register in case of selecting a code by an unauthorized person, the tax inspector will detect this when working with portable non-volatile memory 2 when processing information on a computer. After processing data on a computer, information in a portable non-volatile memory 2 can be erased and then memory 2 is ready for further use.

 In FIG. 2 presents a block diagram of the algorithm of the electronic cash register. When the "Redemption" mode is executed, the information about the cash proceeds is transferred to the FP unit 5. When a portable non-volatile memory unit 2 is connected to the FP unit 5, the microcontroller 4 identifies the code of the portable non-volatile memory 2 and, when matching with the code recorded during registration in the fiscal memory block, information transfer from the FP unit 5 to the memory 2. In the electronic cash register information is retrieved. To obtain data from a portable memory 2, it is connected to a computer device where information is input, the computer device 7 identifies the code of the portable memory 2, and when it is identified in the code comparison circuit 8, information is transferred from the portable memory 2 to the data processing unit 9, where total revenue, tax amount are calculated and a database is formed for each cash register controlled by a tax inspector.
