Description

The invention relates to methods and devices for data processing, used mainly in retail enterprises in cash transactions.

There is a known method of digitizing a document that is a cash receipt for retail customers, consisting of obtaining an electronic identifier of a user ID (online address), sending a digital copy of the cash receipt to the buyer (at his online address), sending a digital copy of the message of departure and the method of sending a digital copy of the cash receipt to the buyer and the accounting service (US patent application No. US 2013/0060713, publ. 03/07/2013). The method is implemented using scanning means (image forming apparatus 105 and 106) for processing a digital copy of a cash receipt with the possibility of saving it in a database and retrieving, if necessary, at the corresponding index. In addition, the optical device is used to generate an electronic user identifier (barcode) in the optical data format, while it is possible to manually enter the user identifier. The method involves the use of a printer for preliminary single printing of a cash receipt and user ID on paper. Management and implementation of the method provides a programmable host unit, to which all optical equipment and a printer are connected.

The disadvantage of this method is the mandatory printing of paper cash receipts and user identifiers, as well as the use of the Internet throughout the customer service cycle, sending an electronic cash receipt to the buyer. Using additional expensive scanning equipment to digitize a paper receipt at each cycle of each customer.

Also known is the "Method and system for archiving data contained in a printed document (cash receipt)", which are used by retailers (French patent No. FR 2982389, published on 05/10/2013, bull. 13/19). The known method includes the formation of an electronic cash receipt by scanning barcodes of goods with the possibility of manual entry, non-cash payment for a purchase using an electronic wallet and an electronic identifier of the buyer’s payment system (bank card), information about which is recorded in the cash receipt. Further, in accordance with the software of the cash register controller, archiving and transfer using the created virtual printer, controlled by the programmable device (101) of the cash register, the generated cash receipt is sent to the data archiving server using the created virtual printer. An encrypted file is sent to the drive of the customer’s mobile device, containing the details of access to the archive server containing encrypted data about the operation performed by the buyer. At the same time, the buyer has the opportunity to store electronic files with access details on an external remote file server (cloud storage) and receive electronic cash receipts from there by his unique electronic identifier generated by the software programmed device of the cash register, as well as store checks on a regular usb flash drive (a storage device that uses flash memory connected via usb ports as a drive) and view the check using a stationary personal About the computer using the details obtained on the usb flash drive.

To scan barcodes from labels of goods forming a cash register receipt, a scanner (104) is used, which allows to automatically identify the purchased products and determines the total purchase amount. To determine the identifier of the buyer, an electronic payment device (103) is used, which ensures payment by credit card and using a mobile electronic wallet accessible via NFC (Near Field Communication). To create an electronic cash register receipt (file), a virtual printer (105) with the ability to print a paper receipt is used, since, firstly, the possibility of using a thermal printer is mentioned, and secondly, the software installation of the device 102 (or the program of the cash register controller 101) about choosing the requirement for printing paper. To transfer the generated file with access details to the data archiving server and receipt information to the customer’s portable device (smartphone), a programmable electronic cash receipt transfer device (102) is used, containing a processor, communication interfaces with a cash register (101) and communication with a smart phone, as well as a card reader (SD card reader). All of the devices mentioned are connected to the cash register, for example, via the USB Universal Serial Bus. The archiving system additionally includes a file server (107), which provides the customer, at his request, with an additional service - storing electronic cash receipts not on a mobile device, but using the network cloud infrastructure for these purposes. Data exchange with the server (107) is performed via the Internet.

The disadvantage of this method is that the user receives on his portable device the details of access to the electronic check, which is stored on the remote server, and is a data set, not a single file. Another drawback is that access to the electronic check, which is stored on the remote server, may be limited (Internet failures or technical problems).

The task to which the claimed invention is directed is to create an electronic cash register receipt with the possibility of quick and reliable transfer of it to a user's portable device via wireless communication.

The problem is solved due to the fact that the method of creating and transmitting an electronic cash receipt includes inputting information about a product by means of a cash register input device and converting information into a digital data stream necessary for generating an electronic cash receipt in the form of a file. The digital stream is transmitted through the serial port to the corresponding port of the controller associated with the device for displaying and inputting information and using the controller, from the received digital data stream, creates a file that is an electronic cash register. The created electronic cash register receipt is stored on the controller’s internal drive, which activates an interactive graphic user interface on the information display and input device, through which users request an electronic cash register and establish a wireless connection between their portable device and the controller. At the command of the controller software, the electronic cash receipt is transmitted, and its reception and display on the screen of the user's portable device is subject to a one-time preliminary download and installation of a special program that provides a secure wireless mode. Next, the user sends a confirmation of receipt of the electronic cash receipt to the controller, which, in turn, transmits the user confirmation in the form of a digital signal to the cash register.

The cash register and controller can be connected via serial communication ports or through LPT ports, as well as via a wireless communication channel.

A cash register as an input device may have a barcode scanner, a QR code or other product code, or a keyboard, or a touch screen.

Software for a mobile device is downloaded from the mobile app store or software developer site.

The controller contains a radio module for wireless communication.

The method is illustrated by the following drawings:

in FIG. 1 is a structural diagram of equipment used in the implementation of a method for creating and transmitting an electronic cash receipt;

in FIG. 2 - an algorithm for creating and transmitting an electronic cash receipt;

in FIG. 3 - a fragment of the interactive graphical interface of the controller.

The method is as follows.

The implementation of the method is possible subject to the preliminary installation on a portable device of the user (buyer) of specialized software downloaded from the application store or from the developer's site, information (links) of which are distributed additionally.

Using an input device 1 (for example, a keyboard) of a cash register 2, a data stream is generated corresponding to the amount of information of at least a standard cash register. The digital data stream through the serial port of the cash register 2 (for example, USB) is fed to the corresponding serial port of the programmable controller 3. The last of the digital data stream creates a file, which is an electronic cash register, stored on the controller’s internal drive 4. At the same time, an interactive graphical user interface 6 is activated on the information display and input device 5 (Fig. 3), by which the user requests an electronic cash register receipt. In this case, the controller generates a command to establish a wireless connection with the portable device of the user 7. Then, by the command of the controller 3, the created electronic cash receipt in the form of a file is transferred to the portable device of the user 7 and stored on its storage device.

Upon receipt of the electronic cash register receipt on the mobile device of user 7, its image is automatically displayed on the screen (Fig. 3), and upon the command of the previously installed program, the portable device 7 sends a confirmation signal of receipt of the electronic cash receipt to the controller 3, which in turn sends a similar signal to the cash register apparatus 2.

If it is not possible to establish a wireless connection with the portable device of the user (buyer), the controller 3 sends the electronic cash receipt created in the form of a file to the printer 8 (for example, FPrint-11) for printing on paper. The connection of the controller 3 with the printer 8 can occur via serial communication ports or via LPT ports, as well as via a wireless communication channel.

The advantages of the described method is safety due to the autonomy of the system.

An additional advantage is the availability and versatility of the system for the buyer, which allows receiving electronic cash receipts in all stores.

Another advantage is the reduction in operating costs by canceling the printing of paper receipts, as well as the reduction in the cost of implementing the system, since the controller is installed in the existing cash system. Also, reducing financial costs is achieved by eliminating the possibility of intentional violation of cash discipline by the seller’s employees (printing blank checks, do not print the check at all).
