Payment system and method for automatic apparatus operated without a network

The present invention relates to a payment system and a payment method for an unmanned device operating without a network. More specifically, a payment terminal capable of short-range communication with a user terminal is mounted on an unmanned device that is not provided with a network connection means and can only pay in cash. The present invention relates to a billing system and a payment method of an unmanned device operating without a network that enables payment of a usage fee of the unmanned device without cash.

Unmanned devices have been provided to sell beverages and industrial products, or to provide printing and laundry services. In the unmanned device, a user pays a relatively small amount of usage fee on site and uses it. It was possible to pay the usage fee by inserting a small amount of cash into the electricity slot or banknote slot installed in the unmanned device.

However, as the use of cards as a socially common payment method increases, users often do not carry cash. As a result, there are frequent situations in which the user cannot use the unmanned device due to lack of cash. To solve this inconvenience, an unmanned device capable of card payment has been developed, but in order to add a card payment function, an unmanned device having no functional problem must be replaced.

Even if the unmanned device is replaced, a replacement cost due to the replacement and a network installation and maintenance cost for using the card payment function occur. In addition, when paying by card, since a payment fee is generated for each payment, a fee fee is also added. In particular, in a commercial environment, such as a coin laundry room, an arcade room, or a doll-drawing room, where a large number of unmanned devices are operated, installation and operation costs may be high when each individual device operates a card payment machine. For this reason, from the point of view of a business operator operating an unmanned device, it is more profitable to operate an unmanned device that can only pay in cash at present compared to the cost incurred to add a card payment function, so unmanned devices with a card payment function are widely used. it's not happening

5 is a diagram illustrating a communication waveform for each band frequency of the sound wave communication of the communication unit according to an embodiment of the present invention.

Referring to FIG. 5 , the communication unit 220 of the payment terminal 200 illustrated in FIG. 3 may communicate with the user terminal 300 using sound waves. Here, the sound wave may be an ultrasonic wave.

When the payment terminal 200 and the user terminal 300 transmit data using ultrasound, the data may be separated and transmitted using ultrasound of different band frequencies. For example, when data '124312243' is transmitted, the data '124312243' is separated, data of '124' using 100 kHz ultrasound, data of '312' using ultrasound of 150 kHz, and ultrasound of 200 kHz Thus, data of '243' can be transmitted. When transmitting ultrasound, the payment terminal 200 and the user terminal 300 may transmit each data at once using ultrasound obtained by synthesizing frequencies of different bands. The data may be separated based on a predetermined number of data digits. According to an embodiment, it is described that ultrasound of one band includes three-digit data, but the present invention is not limited thereto and may include data of one or more digits according to an embodiment.

5 (a) is a synthesized ultrasound of one or more frequency bands, and FIG. 5 (b) is an ultrasound divided into a frequency band of 100 kHz. FIG. 5(c) is an ultrasound divided into a frequency band of 150 kHz, and FIG. 5(d) is an ultrasound divided into a frequency band of 200 kHz. In an embodiment, the ultrasonic waves transmitted to each terminal are transmitted as synthesized ultrasonic waves that are the waveforms of FIG. 5(a), and the terminals receiving the ultrasonic waves are shown in FIGS. 5(b), 5(c), and 5(d). As described above, by separating the ultrasonic waves for each frequency band, the data may be received and combined back into the original data based on a predetermined standard.

When the communication unit 220 of FIG. 3 separates the data by each digit and transmits the data as ultrasonic waves of different frequency bands, the ultrasonic waves of each frequency band may overlap data included in other frequency bands. For example, if the actual data to be transmitted is '1234567890', the communication unit 220 may transmit data '1234567', '4567890', and '7890123' to ultrasonic waves of different frequency bands, respectively. That is, the communicator 220 may transmit data included in other frequency bands by overlapping 4-digit data at the rear end of data transmitted in each frequency band. When the user terminal 300 receives ultrasonic waves of each frequency band and combines the separated data, the user terminal 300 may check whether there is an error in the received data by checking overlapping data. Through this, it is possible to prevent data transmission errors that may occur in ultrasonic communication.

6 is a diagram illustrating a communication waveform for each area of sound wave communication transmitted by a communication unit according to an embodiment of the present invention.

Referring to FIG. 6 , the communication unit 220 of FIG. 3 may transmit the ultrasound to follow a specific rule when transmitting the ultrasound. Here, the specific rule may be that the transmitted ultrasound includes a start area 701 , a blank area 702 , and a counter area 703 . More specifically, the specific rule may be that the start area 701 includes a predetermined waveform indicating the start of data, and after the blank area 702 for a predetermined time, an ultrasound including actual data is transmitted.

The user terminal 300 may receive the ultrasound according to the specific rule and interpret the data. In particular, in order to interpret the actual data, the user terminal 300 may count the peaks or valleys of the ultrasonic waves of the counter area 703 and convert them into data. For example, if the result of counting peaks or valleys for 0.5 seconds in the 150 kHz band is '25241', the '25241' to be transmitted in the 150 kHz band may be a data value.

The communication unit and the user terminal of the payment terminal described with reference to FIGS. 5 and 6 may perform roles opposite to each other according to the direction in which data is transmitted/received.
