[0001] METHOD FOR ELECTRONIC PAYMENT BY USING BLUETOOTH COMMUNICATION, AND SYSTEM THEREFOR [0002]

The present invention relates to an electronic payment method and system using near field Bluetooth communication, and more particularly, to a method and system for electronic payment by interworking a settlement relay server and a merchant settlement apparatus using a near field Bluetooth communication and a beacon sending device of a user terminal ≪ / RTI >

Bluetooth is a short-range wireless technology standard that exchanges information by connecting mobile devices such as mobile phones, notebooks, earphones, and headphones. It is mainly used when a low-power wireless connection is needed in a short distance of about 10 meters.

In the early days, the transmission speed of Bluetooth was only 1Mbps. This was about six times faster than the existing technology, but it was inadequate to transmit high-volume data such as high-quality music or video. Therefore, the popularization of Bluetooth was slower than expected and was used for limited purposes only. But as time went by and a new version of Bluetooth emerged, the speed was noticeably improved. Bluetooth 2.0 up to 3Mbps, Bluetooth 3.0 up to 24Mbps speed up. In recent years, even with the speed of 24Mbps, coin batteries for wristwatches have come up to Bluetooth 4.0, which consumes less power for years.

3 is a flowchart of an electronic settlement method performed in a user terminal 100 supporting Bluetooth communication according to an embodiment of the present invention.

3, an electronic payment method using a beacon technique, which is performed in a user terminal 100 supporting Bluetooth communication, is a method in which a beacon transmission device 400, which is provided in the merchant payment apparatus 300, (S120) of checking the merchant identification information included in the first beacon signal (S120); checking the merchant identification information to adjust the Bluetooth transmission range of the user terminal A step S130 of transmitting a payment information request signal including at least one of user information and merchant store identification information of the user terminal 100 to the merchant payment apparatus 300 corresponding to the merchant store identification information by using Bluetooth communication (S140), acquiring payment information in response to the payment information request signal from the payment relay server 200 (S150), and completing settlement using the acquired payment information (Step S160).

Here, the payment information is generated in the payment relay server 200 based on the merchandise order history, user information of the user terminal 100, and merchant store identification information generated based on the information input by the merchant payment apparatus 300 . At this time, the payment information may be merely the amount that a particular user has to pay to a particular merchant, information that includes the merchandise details, or may be information that includes discount information. Particularly, when the payment information is generated in the payment relay server 200, it can be updated more easily when a discount event or the like is performed in the user terminal 100 or the merchant payment apparatus 300 and can be provided to all the merchants.

In addition, the payment information may be generated in the merchant payment apparatus 300 or in the user terminal 100. [

Here, the first beacon signal further includes an application installation inducing URL information, and when the user terminal 100 receives the first beacon signal, it can support connection to the installation inducing URL. More specifically, conventionally, a beacon signal includes a packet including only an installation inducing URL and a packet including a UUID, but the present invention can use a packet that carries both of them. Accordingly, upon receiving the installation inducing URL, the URL can be displayed in a pop-up form, and the user can access the URL via input such as touch. At this time, a process of confirming whether or not a specific application is installed may be performed in the process of reading the corresponding URL. A more specific installation induction process can be implemented by a general technician in various ways.

Here, the Bluetooth communication may be Bluetooth low energy (BLE). When the low power Bluetooth is used, the battery consumption of the user terminal 100 may be small even in the case of long data transmission, and in the case of the beacon sending device 400, there is an advantage in terms of maintenance.

In addition, the step S130 of adjusting the Bluetooth transmission range of the user terminal by confirming the merchant identification information may be performed by controlling the Bluetooth transmission range of the user terminal 100 within a range of several centimeters to several tens of centimeters, For example, based on at least one of the antenna shape, the antenna impedance, and the transmission power of the user terminal 100.

Here, it may further include restoring the adjusted Bluetooth transmission range after the step (S140) of transmitting the payment information request signal using the Bluetooth communication. By restoring the transmission range, it is possible to prevent a failure in the user terminal 100 performing Bluetooth communication for other purposes.

By reducing the Bluetooth transmission range of the beacon sending device 400 and the user terminal 100 as described above, it is possible to prevent information leakage in a data communication process than a general beacon related technique, thereby improving security performance.

Specifically, the transmission range can be assured by wireless communication using an antenna. The impedance matching is a device part (transmitting side) for generating an electromagnetic wave. Here, the beacon transmitting device 400, Corresponds to the transmitting side, and since the antenna receives the transmitting signal, it corresponds to the receiving side, and the impedances between the transmitting side and the receiving side are equal to each other. This is because the maximum power can be delivered to the antenna by adjusting the impedances of both antennas equally. Therefore, if the impedance of the beacon transmitter side (i.e., transmission side) is artificially changed, And consequently, the transmission power is adjusted.

FIG. 4 shows an exaggerated representation of the shape of the antenna. However, when the shape of the antenna is modified in this manner, the impedance is changed, so that the transmission range can be reduced to a close range. In addition, .

In addition, a method of changing the voltage ratio of the beacon transmitting device 400 and the antenna may be considered. In the conventional antenna, a device called a voltage balun can be installed. In principle, this is used to match the impedance by adjusting the voltage ratio. However, if it is used in reverse, the impedance ratio is reduced by adjusting the voltage ratio, .

Also, a method of reducing the Tx power of the beacon sending apparatus 400 by software may also be used.

In the above-described method, the Bluetooth transmission range in the user terminal 100 can be similarly applied.
