In the case of a digital receipt, both a method of directly transmitting from the cash receipt issuing apparatus 200 to the user device 100 and a method of transmitting via the internet network or a communication network may be used. As such, when wireless communication is used in the cash receipt issuing system using the user communication device, the use of the digital receipt can be more stably expanded.

Figure 4 is a flow chart showing a cash receipt issuing process of the cash receipt issuing system of the preferred embodiment of the present invention.

Referring to Figure 4 describes the process of issuing a cash receipt of the present invention using the RFID method, first, the cash receipt issuing apparatus 200 receives a user identification code provided by the user device 100.

Receiving the user identification code may be provided by the user (buyer) to provide the goods before or after checking the goods at the counter. In addition, when the RFID communication module provided in the user device 100 is a passive type, the user device 100 is approached to the cash receipt issuing apparatus 200 to induce the fourth communication unit 230 of the cash receipt issuing apparatus 200. The second communication unit 190 of the user device 100 transmits the user identification code by the current. Alternatively, the second communication unit 190 of the user device 100 may be activated by a wake-up element provided in the fourth communication unit 260 of the cash receipt issuing apparatus 200 to transmit in a semi-active type of transmitting an identification code. . Preferably, when the user clicks or touches an element designated as a button on the display / input unit 130 of the user device 100, the second communication unit 190 may be activated to provide a user identification code.

Then, the purchase history of the user input from the seller is transmitted to the user device 100 (S102). In this step, the purchase history transmission may be directly transmitted to the user device 100 through the RFID communication module of the fourth communication unit 260, or the text message or the user device through the Internet network or the communication network. The digital code can be converted into a document format at 100.

Next, when the user confirmation signal and the deposit confirmation signal transmitted from the user device 100 is input (S103), the process proceeds to the next step and transmits the approval request signal to the cash receipt issuing server 300 (S104). The approval request signal may include information about a corresponding cash transaction, such as a user identification code, an identification code of the cash receipt issuing device 200 itself, and a purchase history of the corresponding user.

If the confirmation signal is not received from the user device 100 in step 103, the process returns to step 102 and transmits the purchase history back to the user. This can be done by sending a signal corresponding to the rejection when the user finds an error or needs correction after checking the purchase history. This step can be very useful for the user. For example, in the previous transaction, when there are many purchases, the user checks the receipt later to check whether there is an error, but in the present invention, the user can check at the moment and correct the error. There is this. In addition, the deposit confirmation signal may be a signal input from the seller.

However, the process of receiving the confirmation signal from the above user device 100 may be omitted. For example, the user (buyer) can be confirmed through the display provided in the cash receipt issuing device 200 as in the conventional method.

When the approval signal is received from the cash receipt issuing server 300 (S105), it issues a cash receipt (S106).

In the step of issuing a cash receipt in step 106, the electronic receipt is preferably transmitted to the user device 100. For example, the cash receipt issuing apparatus 200 transmits a digital code which can be converted into an electronic receipt document or an electronic receipt document to the user device 100 through an internet network or a communication network. Alternatively, the cash receipt issuing apparatus 200 may use a method of direct transmission through the RFID wireless signal to the user device 100.

2 and 3 described above mainly describe a method of using RFID wireless communication, the cash receipt issuing system of the present invention can provide a user identification code as an optical code in the user device 100. . For example, the optical code may be provided as a barcode or a QR code as described above. This is to recognize the user identification code by the scanner provided in the cash receipt issuing device 200, and the rest of the process other than receiving the confirmation signal from the user device 100 can be made similar to using the RFID wireless communication.

<Account book system>

It may likewise be a text message, a documented file, or a digital code, and the user device 100 includes information corresponding to the user's income and expenses. Such approval details are preferably formed in a predetermined format so that the user device 100 can extract the contents corresponding to each item and record the content in the corresponding item.

The financial company server 410 or 420 is a financial company server having a user account such as a bank company server or a card company server that records contents of the user's income and expenses. The financial company servers 410 and 420 transmit a digital code of a predetermined format to the user device 100 whenever a user's income and expenses are generated. For example, when an event related to income such as payroll or an event related to expenses such as money transfer or card approval is generated, it is transmitted to the user device 100.

In particular, the financial company server (410, 420) of the present invention, the item corresponding to the digital income and expenditure is automatically sent to the user device 100, which is the server company's approval only to the user device 100 This is different from the conventional method of transmitting. The existing authorization history notification service with the card notifies the user when the authorization is made using the card by text message. The main purpose was to prevent theft of the card or to confirm normal approval. Therefore, most of the users are not able to check in real time when the money is deposited into their bankbook or when the direct debit is made, they have no choice but to connect to the server of the card company or the financial company. However, in the present invention, it can be confirmed in real time, and also has the advantage that can be confirmed in a batch on the user device (100).

The user device 100 is provided with, for example, an account book program or an application. Such an account book program is preferably installed in the user device 100 that the user carries, but is not necessarily limited thereto, and a program or application provided in a web space or other communication or Internet-connected device designated by the user. Can be.

The details sent to the digital code include information on the user's balance, income, and expenditure, and thus the digital code has a predetermined format.

When the user device 100 receives data on income or expenses from the cash receipt issuing server 300 or any financial institution server 410 or 420, the user device 100 extracts the necessary information from the data and automatically writes the information into the book program. Done.

In addition, the account book program or book program described above may be provided in a web space or other computer device specified by the user in addition to the user device, the cash receipt issuing server 300, the financial company server, and the credit card company server to the user specified location Of course, you can also send information about your income and expenses.

In real life where the use of cash is small, the account book system of the present invention can be very effective. In particular, even if the user can not afford to record by hand, since the income and expenses are automatically arranged after setting in advance, it is possible to plan and manage the income and expenses at any time. In addition, the account book system of the present invention provides the effect of viewing the contents of the user account of the financial company server, which is managed at the same time.

In the foregoing detailed description of the present invention, specific embodiments have been described. However, it will be apparent to those skilled in the art that various modifications can be made without departing from the scope of the present invention.
