Description

1. FIELD OF THE INVENTION

The present invention relates to a method for ordering food and performing a payment using local wireless communication, and more particularly to a system and a method for ordering food using RFID in which when a customer selects a menu item and makes a payment for it by using a mobile terminal having a built-in RFID device or an external RFID device, this is registered to a kitchen server and a completion message is transmitted to the mobile terminal when the food is completed, or a menu item ordered by the mobile terminal is simply authorized through a tag stored in the mobile terminal, so that the customer can easily take out the ordered food.

2. DESCRIPTION OF THE PRIOR ART

Conventionally, a customer should wait for his/her turn in line for ordering food in a fast food restaurant such as McDonald's or Burger King. Therefore, it takes much time for determining and ordering a menu item when the restaurant is crowded, and when the customer is not sure of a previous knowledge for the menu items, so that a next person in line should wait for an even longer time.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First Exemplary Embodiment

FIG. 1 is a diagram illustrating a system for ordering food using RFID according to a first exemplary embodiment of the present invention.
RFID is one field of an auto-ID, such as bar information, magnetic stripes, and an IC-Card, which employs a method of wirelessly identifying information of an object using radio frequency.
A principle of the RFID is to receive tag information including information of a corresponding object through an antenna so as to use the tag information for obtaining the information on the corresponding object, which uses an electric wave. Therefore, the RFID is resistant to an environmental influence, can be identified at a high speed and at a remote distance, and a unique information number is assigned to a tag during manufacturing of the tag, thereby preventing counterfeiting.
A system for ordering food using the RFID according to a first exemplary embodiment of the present invention provides a system by which a user entering a fast food restaurant or a restaurant can order the food, i.e. a product, using the RFID. The system includes a mobile terminal 100, a mobile communication network 300, an RFID system 400, a main server 500, a credit card company server 600, and a Point of Sales (POS) system 700.
The mobile terminal 100 reads a tag 220 provided to a menu item 200 while being connected to a built-in RFID module or an external RFID device (so-called a round 105).
The mobile terminal 100 transmits the read information of the tag 220 to the RFID system 400 through the mobile communication network 300, a relay server 410 of the RFID system 400 transmits the tag information received from the mobile terminal 100 to a User Agent Profile (UA profile) 420 so as to authorize a subscriber, and when the authorization is completed in the UA profile 420, the tag information is provided to an Object Directory Service (ODS) server 430.
The ODS server 430 manages an Object Identification Service (OIS) address corresponding to the tag information and a service URL and provides the OIS address and service URL to the relay server 410.
The relay server 410 access the OIS and an Object Tracking Service (OTS) through the OIS address and inquires information related to the tag information. Here, an example of the information related to the tag information is the tag issuance, the tag discard, events that occurred during the distribution, or the like.
The relay server 410 provides service URL information obtained from the ODS server 430 to the mobile terminal. Here, the service URL information is an URL of the main server 500 storing information on the food, i.e. the product corresponding to the tag information, and is transmitted to the mobile terminal 100.
The main server 500 stores and manages the product information corresponding to the tag information of the RFID so as to provide it to the mobile terminal 100, performs the payment according to the product order by the mobile terminal 100, and transmits the payment result to a Point Of Sales (POS) server 720.
For example, the main server 500 is a center management server of the fast food restaurant, such as McDonald's or Burger King and is connected to the POS system 700 of a branch restaurant.
The main server 500 transmits a payment methods list to the mobile terminal 100. When the mobile terminal selects and requests a payment of a payment amount being added to a charge of the mobile terminal 100 in the payment methods list, the main server 500 transmits a payment amount according to the order item to an accounting server (not shown) of the mobile terminal 100.
If the main server 500 receives a registration notice message of the payment amount from the accounting server, the main server 500 assigns an order number to the order item and transmits the order item, the order number, and a phone number of the mobile terminal to the POS server 720 of the POS system 700.
If the mobile terminal 100 requests a cash payment in the payment methods list transmitted from the main server 500, the main server 500 transmits the order number corresponding to the order item together with the order list to the POS server 720 and the mobile terminal 100 at the same time. Therefore, payment completion information indicating that the user of the mobile terminal 100 completes the cash payment through an OFF-Line terminal 740 of the POS system 700 is registered, and the main server 500 transmits the payment completion information to the POS server 720.
If the mobile terminal 100 requests a card payment in the payment methods list transmitted from the main server 500, it is inquired whether a card payment history of the mobile terminal 100 is stored in memory of the mobile terminal 100 or the main server 500. If the card payment history is stored, the main server 500 reads the information of the card, identifies the user, and performs the payment. The main server 500 is linked with the credit card company server 600 so as to identify the user, and transmits the payment information to the credit card company server 600 after completing the payment.
At this time, if the card payment history is not stored or if the user wants to make the payment with another card, the main server 500 provides a WAP page for inputting information of another card on a payment screen of the mobile terminal 100, and authorizes the card while being connected to the credit card company server.
At least one POS system 700 linking with the main server 500 includes the POS server 720, the Off-Line terminal 740, and the kitchen server 760.
The POS server 720 transmits the order information according to the payment result received from the main server 500 to the kitchen server 760.
The POS server 720 lists up the order items through the mobile terminal 100 and the OFF-Line terminal 740 in a time sequence of the payment completion, manages them in total, and transmits the order list to the kitchen server 760 so as to make the food to be prepared.
The kitchen server 760 adds an order waiting state item on the order list received from the POS server 720 so as to display it on the screen. When the product according to the order, i.e. food, is completed, the order waiting state item is changed to an order completion item to be registered, and the kitchen server 760 transmits a guide message informing the order completion of the food to the POS server 720. Then, the POS server 720 transmits the guide message to the mobile terminal 100 through the mobile communication network 300, and when the user of the mobile terminal 100 receives the food, the order information is deleted on the order list. The guide message includes a text message, a voice message, a multimedia message including at least one text, image, and moving picture.
The operation of the present invention configured according to the first exemplary embodiment of the present invention will be described in more detail.
The tag information is read from at least one tag 220 matching to each of a plurality of products of the menu 200 using the mobile terminal 100 having the built-in RFID module or the external RFID device 5310.
The mobile terminal 100 transmits the tag information to the RFID system 400, obtains the URL information of the main server 500 storing and managing the product information corresponding to the tag information from the RFID system 400, and accesses the main server 500.
The main server 500 transmits the product information corresponding to the tag information to the mobile terminal 100 S320. As shown in FIG. 5, the product information includes at least one of a product name, a product price, the place of origin, ingredients used in the product, and total calories if the product is food.
When the mobile terminal 100 fills out the number of the product and transmits an order request message to the main server 500, the main server 500 performs the payment according to the payment request S330 and S340.
There are three payment methods performed in the main server 500 as follows.
First, when the mobile terminal 100 selects the cash payment in the payment methods list, the order number corresponding to the order item are transmitted together with the order item to the POS server 720 and the mobile terminal 100, and when the user of the mobile terminal 100 receiving the order number makes the cash payment, the payment completion information is registered to the POS server 720 and the main server 500.
As shown in FIG. 6, a window for selecting the payment method is popped up on a screen of the mobile terminal 100, and if an item [1. cash] is selected in the popped-up window, the guide message is displayed on the screen of the mobile terminal 100 together with the order number.
Second, the mobile terminal 100 selects a phone bill of a payment amount being added on the charge of the mobile terminal 100 in the payment methods list received from the main server 500, the main server 500 transmits the payment amount of the order item to the accounting server of a mobile communication company to which the mobile terminal 100 belongs. Referring to FIG. 7, the WAP page authorizing for identifying a service charge added when the payment amount is summed up to the charge of the mobile terminal and the person in question is displayed on the screen of the mobile terminal 100.
At this time, the main server 500 receives a message informing the registration of the payment amount from the accounting server, assigns the order number to the order item, and transmits the order item, order number, phone number of the mobile terminal to the POS server 720, so as to make the food corresponding to the order item to be prepared.
Third, when the mobile terminal 100 selects the card payment in the payment methods list, it is inquired whether the card payment history of the mobile terminal 100 is stored in the memory of the mobile terminal 100 or the main server 500. If the card payment history is stored, the card information is read and the payment is performed after identifying the user. FIG. 8 illustrates the WAP page implemented to display the information on the credit card on the screen of the mobile terminal because the credit card used for paying the charge of the mobile terminal is stored in the main server, authorize the user, and make the payment.
However, as shown in FIG. 9, if the card payment history is not stored or if the user wants to pay with another card, the user inputs the card information on the payment screen of the mobile terminal 100. If the result of the authorization performed by the credit card company server is authorization, the order item and the phone number of the mobile terminal 100 are transmitted to the POS server 720.
When the payment is completed through one of three methods, the POS server 720 connected to the main server 500 transmits the order item to the kitchen server 760 S350. For example, when the payment for the order is completed or the order is requested, the order number is generated and the generated order number are transmitted together with the order item between the POS server 720, kitchen server 760, and the mobile terminal 100.
The order item is displayed on the screen of the kitchen server 760 together with the [order waiting] item, and when the product, i.e. the food, is completed and the order completion is registered to the kitchen server 760, the order completion message is transmitted to the POS server 720, and the POS server 720 displays the order number on a display unit or transmits the order completion message to the mobile terminal 100 S360 and S370.
If the order items through the mobile terminal 100 and the OFF-Line terminal 740 are registered to the POS server 720, the POS server 720 lists up the order item in a time sequence of the payment completion, manages them in total, and periodically transmits the order list to the kitchen server 760.
Before the kitchen server 720 transmits the order completion state to the mobile terminal 100, it is possible that the mobile terminal 100 transmits the message requesting the cancel or change of the order item to the POS server 720.
The main server 500 transmits a message inquiring the additional order to the mobile terminal 100. When an additional order request is received from the mobile terminal 100, the main server 500 transmits the WAP page according to the additional order request to the mobile terminal 100.

Second Exemplary Embodiment

FIG. 2 is a diagram illustrating a system for ordering food using RFID according to a second exemplary embodiment of the present invention.
The system for ordering food using the RFID according to a second exemplary embodiment of the present invention is a system implemented to order the food and make a payment for it in advance before the user desiring the take-out arrives at the fast food restaurant or the restaurant, and authorize the user within a short time using the tag built-in the mobile terminal when the user arrives, so as to enable the user to take out the ordered food.
The system for ordering food includes the construction elements similar to those of the first exemplary embodiment, but the construction of the POS system 700 is different from that of the first exemplary embodiment.
Further, the mobile terminal 120 according to the second exemplary embodiment stores unique tag information and it is not necessary for the mobile terminal 120 to include a built-in or an external RFID device reading the tag, like the first exemplary embodiment.
The main server 500 provides the mobile terminal 120 with a menu for ordering the food, provides the payment screen according to selecting the menu item, calculates an expected arrival time based on location information received from the mobile terminal 120, and performs the user authorization based on the tag information. If the user authorization is completed, the main server 500 transmits the information on the order, the expected arrival time, and the tag information to the POS server 720.
For example, when the mobile terminal 100 accessing the main server 500 transmits the tag information and the location information, the main server 500 transmits the tag information to the RFID system 400, authorizes the mobile terminal 120 based on the tag information, and receives the authorization result from the RFID system 400. That is, the main server 500 authorizes the mobile terminal 120 and then transmits the WAP page related to the product order to the mobile terminal 120.
The POS system 700 includes the POS server 720, an RFID reader 780 reading the tag information stored in the mobile terminal 120, and the kitchen server 760.
The RFID reader 780 is resistant to an environmental influence and can recognize the RFID at a high speed. Therefore, for example, if the user of the mobile terminal 100 orders the menu item while driving and arrives at the fast food restaurant or the restaurant, the RFID reader 780 can read the tag information stored in the mobile terminal 120 without the user getting out of the car.
The POS server 720 compares the tag information transmitted from the RFID reader 780 with the tag information provided from the main server 500 and determines the authorization. If it is determined to be authorized, the POS server 720 transmits the order information to the kitchen server 760.
The function of the kitchen server 760 is identical to that of the first exemplary embodiment, so the description thereof will be omitted. Further, the payment method according to the order of the user in the main server 500 is identical to that of the first exemplary embodiment, so the description thereof will be omitted.
The operation of the present invention configured according to the second exemplary embodiment of the present invention will be described in more detail.
The mobile terminal 120 accesses the main server 500 through the mobile communication network 300 before the user arrives at the fast food restaurant or the restaurant equipped with the POS system 700 S410.
At this time, the mobile terminal 120 accesses the main server 500 through the mobile communication network 300, selects the menu item, and makes the payment for it so that the order is completed S420. The payment method through the main server 500 is identical to that of the first exemplary embodiment so the description thereof will be omitted.
The mobile terminal 120 completing the payment transmits the unique tag information and location information of the mobile terminal 120 to the main server 500 S430.
The main server 500 calculates the expected arrival time based on the location information and authorizes the user based on the tag information S440. For a practical example, the expected arrival time can be registered to the main server 500 by the mobile terminal 120.
When the user authorization is completed, the main server 500 transmits the order information, the expected arrival time, and the tag information to the POS server and the POS server 720 transmits the order information to the kitchen server 760 so as to make the food according to the order information to be prepared in the kitchen S450 and S460.
When the order completion is registered to the kitchen server 760, the order completion message is registered to the POS server 720 and is transmitted to the mobile terminal 120.
The tag information stored in the mobile terminal 120 is read through the RFID reader 780 connected to the POS server 720 and the POS server 720 compares the tag information provided from the main server 500 and the tag information read from the mobile terminal 120. If the information corresponds to each other, the POS server 720 authorizes the user and provides the user of the mobile terminal 120 with the completed product, i.e. the food, S470 and S480.

Third Exemplary Embodiment

FIG. 10 is a flowchart illustrating a method for remotely ordering food using RFID according to a third exemplary embodiment of the present invention. According to FIG. 10, the user also can select a neighboring franchised restaurant using the location information of the mobile terminal.
Here, the mobile terminal 120 according to the second exemplary embodiment stores unique tag information and it is not necessary for the mobile terminal 120 to include the built-in or external RFID device reading the tag, like the first exemplary embodiment.
The mobile terminal 120 drives an application for the remote order and transmits its location information to the main server S510 and S520. If the mobile terminal 120 does not have the application or needs to be version-updated, the mobile terminal 120 downloads the application from the main server 500.
When the mobile terminal 120 selects the menu item provided by the application, the menu item and a the franchised restaurants list corresponding to the location information are displayed on the screen of the mobile terminal 120 S530.
As a practical example, when one restaurant in the franchised restaurants list is selected, sub-menu items corresponding to the franchised restaurants are displayed, and when one of the sub-menu items is selected, the payment request message is transmitted to the mobile terminal 120.
As another practical example, when the mobile terminal 120 selects the franchised restaurant in the franchised restaurants list, the location information of the franchised restaurant is displayed on the screen of the mobile terminal 120. At this time, if the location information of the franchised restaurant is not stored in the mobile terminal 120, the main server 500 provides the location information of the franchised restaurant S540.
When the main server 500 transmits the payment request message for the menu item to the mobile terminal 120 and the payment is completed S550 and S560, the main server 500 transmits subscriber information stored in the RFID tag of the mobile terminal 120 and the order item to the POS system 700 S570.
The subscriber information includes at least one of a Mobile Identification Number (MIN) and Mobile Directory Number (MDN) of the mobile terminal.
The POS system 700 reads the subscriber information from the RFID tag and compares it with the subscriber information received from the main server 500. If the subscriber information corresponds to each other, an accept message of providing the product corresponding to the order item is displayed on the screen of the POS system 700 and the accept message is also provided to the mobile terminal 120 in the practical example S580.
Further, when the payment is completed, the main server 500 calculates the expected arrival time based on the location information of the mobile terminal 120 and the franchised restaurant so as to transmit it to the POS system 700, and the location information of the franchised restaurant is displayed as a map on the screen of the mobile terminal 120. Further, if the mobile terminal 120 requests a road guide service through the main server 500, the main server 500 provides a route from the location of the mobile terminal 120 to the franchised restaurant.
It is possible that the main server 500 receiving a preparation complete message of the product corresponding to the menu item from the POS system 700 transmits the preparation complete message to the mobile terminal 120.

Fourth Exemplary Embodiment

FIG. 11 is a flowchart illustrating a method for remotely ordering food using RFID according to a fourth exemplary embodiment of the present invention and FIG. 12 is a diagram illustrating a WAP page displayed on a mobile terminal. In FIG. 11, it is possible to use the information of the franchised restaurant by using the location information of the mobile terminal as in FIG. 10.
Referring to FIGS. 11 and 12, the mobile terminal 120 drives the application for the remote order and selects the menu item and a brand prior to arriving at the franchised restaurant of the fast food restaurant or the restaurant equipped with the POS system 700 S610 and S620.
FIG. 12 specifically illustrates an example of the screen for selecting the menu item and brand. Here, the user selects a kind of food, such as coffee, a hamburger, or the like. When the user selects the coffee, the user selects the brand of coffee. Then, if the user selects the brand Starbucks, the list of the menu item provided from the brand Starbucks is displayed so that the user selects the menu item in the displayed list again. The method of selecting the menu item is merely an example, and is not limited the above method.
Returning to FIG. 11, the menu item and the information of the franchised restaurant selected by the mobile terminal 120 are transmitted to the main server 500 through the mobile communication network 300, and the main server 500 transmits the payment request message corresponding to the selection to the mobile terminal 120 so as to perform the payment S630 and S640.
After the payment is completed, the main server 500 measures the location information of the mobile terminal 120 using a location positioning server (not shown) and then downloads the location information to the mobile terminal S650. Then, the main server 500 downloads the information of the franchised restaurant corresponding to the location information S660.
Then, the franchised restaurants list corresponding to the location information is displayed on the mobile terminal 120. If the mobile terminal 120 selects the franchised restaurant in the franchised restaurants list, the location information of the franchised restaurant is displayed on the mobile terminal 120.
Further, as the mobile terminal 120 selects the franchised restaurant, the main server 500 transmits the subscriber information stored in the RFID tag of the mobile terminal 120 and the order item to the POS system 700 S670.
