It is connected to the selection switch 11 of item '2' and the combination capable of displaying '2' among the seven segments. Therefore, when the at least one selection switch 11 is turned on, the display unit 13 may display a combination of the seven connected segments connected to the selection switch 11 and the user visually selects the menu.

The determining step of the transmission switch 16 is a step of determining whether the transmission switch 16 is turned on in the radio tag 14. Here, the transfer switch 16 is a touch-type button that is driven by the power supplied from the rectifier 15 to apply a transmission signal to the radio tag 14 when the user turns on.

In the transmitting step S15, when the transmission switch 16 is turned on in the wireless tag 14 and a transmission signal is applied, the wireless reader 20 sends an order signal including menu information selected by the selection switch 11. ). The decoder 12 decodes the selection signal output by turning on the selection switch 11, converts the selection signal into a digital signal, and applies it to the radio tag 14. Accordingly, the radio tag 14 transmits an order signal to the radio reader 20 including a selected menu and a table number on which the radio menu board 10 is located or a unique identification code assigned to the radio tag 14. do.

As described above, the wireless menu board 10 transmits an order signal to the wireless reader 20, and the wireless reader 20 transmits an order signal to the order terminal 30. Thereafter, the order terminal 30 transmits the order details including one or more menus included in the received order signal to the kitchen terminal, and proceeds with the cost settlement and payment. This will be described in the order step (S20) of the order terminal 30 below.

9 is a flowchart illustrating a payment step of the order terminal 30 in the order method using the wireless menu board according to the present invention.

9, the payment step (S20) of the order terminal 30 according to the present invention is an order receiving step (S22) for receiving the order signal received through the power-on step (S21) and the wireless reader (20). And, a storage step (S23) for storing the received order signal, a display output step (S24) for outputting the order history, and a sending step (S25) for transmitting the order history to the printing or kitchen terminal 70 and It includes a payment judgment step (S26) for determining the order amount and determining whether the payment is made, and a receipt output step (S28) for outputting a receipt of the amount paid after the payment determination step (S27).

The order receiving step (S22) is a step in which the control unit 32 receives the order signal through the communication unit 31. In this case, since the wireless reader 20 and the order terminal 30 are connected by wire or wirelessly, the wireless reader 20 receives the order signal of the wireless menu board 10 through the wireless reader 20.

In the storing step S23, the control unit 32 stores the order signal received through the communication unit 31 in the storage unit 33. The controller 32 stores the number of the table included in the order signal, the ordered menu, and the quantity in the storage unit 33 together with the date and time. Here, preferably, the control unit 32 calculates and stores a payment scheduled amount by calculating a price for each menu included in an order signal received through the wireless reader.

The display output step (S24) outputs to the display 34 the order details including the menu name and quantity stored in the storage step in the storage step, the table number, and the payment amount calculated on the price of the ordered menu. It's a step.

In the transmitting step, the control unit 32 applies an order signal received from the wireless reader 20 to the printer 60 to output an order document including the order details and / or to transmit to the kitchen terminal 70. Step. The control unit 32 transmits an order signal transmitted from the wireless reader to the kitchen terminal 70. Here, the kitchen terminal 70 is a display installed in the kitchen and receives and outputs the order details by wire or wireless communication with the order terminal 30.

Or in the present invention is provided with a printer (60) that can output the order when not connected to the communication terminal or the kitchen terminal 70 in the order terminal 30 as described above. At this time, the control unit 32 outputs the order history stored in the storage unit 33 to the printer 60 and the user directly delivers the order.

In addition, the order terminal 30 calculates the price of each ordered menu, and stores the total amount and payment in the order details. In this case, the user may input the payment amount and type (for example, card payment or cash payment) by operating the input unit 35 when the customer pays with the card terminal 50 or cash. The control unit 32 stores the payment amount and type input from the input unit 35 in the control unit 32.

The present invention is a standby time from the customer because the customer proceeds through the wireless menu board having a circuit block such as the wireless tag 14 and the rectifier 15 by the electronic ink and roll-to-roll printing technique as described above Can be reduced. In addition, on the store side, the customer's order can be delivered directly to the kitchen through communication.
