FIELD OF THE INVENTION
The present invention relates to methods and apparatus for creating and maintaining customer information.
BACKGROUND OF THE INVENTION
Many quick-service restaurants and other businesses have a “drive-through” which allows customers to place an order and also receive the ordered items without exiting their vehicle. A typical drive-through is a roadway equipped with a speaker and microphone to allow a customer in a vehicle to interact with a cashier operating a remote point-of-sale (POS) terminal. A drive-through allows customers to make purchases more conveniently, and consequently businesses with drive-throughs tend to promote customer satisfaction and customer loyalty.
However, applicants have recognized that drive-through customers may be provided with additional benefits. In particular, drive-through customers may be provided with customized benefits in a manner not addressed by the prior art.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide drive-through customers with customized benefits.
In accordance with the present invention, an apparatus is provided for generating an image of a license plate and determining license plate characters from the image. Then, a database is searched to determine if there is a customer record that corresponds to the license plate characters. If so, the customer record is retrieved and information about the customer is available. Otherwise, a customer record is created. The created customer record corresponds to the license plate characters and stores transaction data that represents a transaction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Heretofore, restaurants and other businesses have not been able to differentiate between drive-through customers, much less customize orders (sets of items to be purchased) for drive-through customers or otherwise benefit from the ability to identify drive-through customers. In particular, in accordance with the present invention a database of customer information may be created in a passive, unobtrusive manner without forcing customers or merchants to depart from their existing practices. Applicants are unaware of any such prior art systems for providing additional benefits to drive-through customers. Since customers may be identified by their license plates, the customers can be provided with customized service in a manner not recognized or described by the prior art. For example, customers at a drive-though may be provided with customized services such as (i) custom item prices, (ii) custom menu arrangements, (iii) the ability to collect remotely-ordered items, (iv) the ability to have default orders processed, (v) customized suggestive sale offers, (vi) benefits for participating in many transactions, (vii) benefits for participating in transactions with great frequency, and (viii) the ability to periodically collect items that are complimentary or prepaid.
Referring to FIG. 1, an apparatus 100 comprises a user communication device 110 in communication with a merchant controller 115. The user communication device 110 may be, for example, a computer or a telephone operated by a customer that places a remote order. Accordingly, the user communication device 110 is typically located remotely from the merchant controller 115, and may be located in the customer's home. The merchant controller 115 is a computer or similar control device that directs the operation of various devices of a restaurant or other business, as described in further detail below. The merchant controller 115 is typically but not necessarily located in a store building of the business.
The merchant controller 115 is also in communication with POS terminals 120, 125 and 130. The POS terminals may be, for example, cash registers located in the store building of the business. Although three POS terminals are shown in FIG. 3, any number of POS terminals may be in communication with the merchant controller 115.
A menu board display 135, such as the Digital MenuBoardTM by Siren Technologies of Chicago, Ill., is in communication with the merchant controller 115 and is operable to display items which may be ordered and corresponding prices for the displayed items, as commanded by the merchant controller 115. The menu board display 135 may be positioned to allow drive-through customers to view the menu board display 135 before (or while) ordering in the drive-through. A speaker 137 and a microphone 138 in communication with the merchant controller 115 allow drive-through customers to communicate with store personnel, such as cashiers operating POS terminals, that operate respective speakers and microphones (not shown) for talking to and listening to the drive-through customers in a manner known in the art. The speaker 137 and the microphone 138 need not be in communication with the merchant controller 115, but may instead be solely in communication with the corresponding speaker and microphone of store personnel.
Vehicle sensors 140 and 145 are positioned on opposite sides of a roadway 155 such as a drive-through alley in a fast food restaurant. The vehicle sensors 140 and 145 are adapted to detect the presence and/or the absence of a vehicle 150 located on the roadway 155. The vehicle sensors 140 and 145 may comprise, for example, pressure sensors located beneath the roadway 155 that detect the weight of the vehicle 150. Alternately, vehicle sensors 140 and 145 may comprise, respectively, a light transmitter and a receiving photo sensor (an optical detector) that cooperate to detect the presence of the vehicle 150 when the transmitted light is blocked by the vehicle 150 and thus is not received by the receiving photo sensor. Other means for detecting the presence and the absence of a vehicle will be understood by those skilled in the art.
The merchant controller 115 is also in communication with an imaging sampler 160, which may comprise a video camera that reads (“samples”) an image of a license plate 165 attached to the vehicle 150 and generates a corresponding image signal. The image signal may be a digital image. The image sampler 160 may further be operable to focus on the license plate 165 of the vehicle 150. In alternate embodiments, the merchant controller 115 may direct the focusing on the license plate 165. Generated image signals are transmitted to the merchant controller 115, which is operable to store and recognize the characters on the license plate 165, as described below. For a description of prior art systems for generating images of license plates and determining a set of license plate characters from the image, one of ordinary skilled in the art may refer to U.S. Pat. No. 4,878,248 to Shyu et al.; U.S. Pat. No. 4,817,166 to Gonzalez et al.; and U.S. Pat. No. 5,081,685 to Jones, III et al., each incorporated by reference herein as part of the present disclosure. After the license plate characters have been recognized, the image may be retained for future comparison or analysis, if desired.
Referring to FIG. 2, in an alternate embodiment of the present invention there may be a plurality of merchant controllers, each directing the operations of a different merchant. Furthermore, each merchant controller may be centrally controlled, allowing the merchant controllers to cooperate in a manner described below. A user computer 210 is in communication with an Internet service provider (“ISP”) computer 220. The user computer 210 may perform some or all of the functions of the user communication device 110 (FIG. 1). The user computer 210 is typically a personal computer operated by the customer and equipped to access the Internet or other electronic network. The ISP computer 220 is a computer that enables the user computer 210 to access the Internet in a manner known in the art. Accordingly, the ISP computer 220 may be of the type controlled and/or operated by America Online, Prodigy, or Microsoft for offering Internet connectivity and content to users.
The ISP computer 220 is in turn in communication through the Internet with merchant controllers 230, 240 and 250 in a manner known in the art. In another embodiment of the present invention, the user computer 210 may be provided with access to the Internet by another computer besides the ISP computer 220, while the ISP computer 220 may enable the merchant controllers to access the Internet.
As is also known in the art, the merchant controllers 230, 240 and 250 may control “web sites” that may be accessed by the user computer 210 upon entering appropriate commands. Each merchant controller may perform some or all of the functions of the merchant controller 115 (FIG. 1). In particular, each merchant controller may direct the operations of a different store. Although three merchant controllers are shown in FIG. 2, any number of merchant controllers may be in communication with the ISP computer 220 without departing from the spirit and scope of the present invention.
The ISP computer 220 may perform many of the processes described below as performed by a merchant controller, especially those processes that are performed for more than one merchant controller. The ISP computer 220 may also store data that is used by more than one merchant controller. Accordingly, the ISP computer may centrally control the merchant controllers, as described in detail below.

The default order database 332 may further store default items that are customized versions of conventional items (e.g. a cheeseburger with extra cheese and no ketchup). Such default items could also be displayed by the menu board display 135 (FIG. 1) to the customer.
In general, information stored about a customer is considered to be stored in a “customer record”. Accordingly, each of a plurality of customer records corresponds to a customer. Information that is stored in the customer database 424 may be considered part of a respective customer record. In addition, the data stored in the complimentary item database 328, the custom price database 330 and/or the default order database 332 may also be considered part of a respective customer record. Similarly, the data stored in the complimentary item database 328, the custom price database 330, and the default order database 332 may instead be stored in the customer database 424. Further data may be stored for each customer. For example, each time the an image of a license plate is generated, the image may be stored in the customer record for future comparison and/or analysis.
Referring to FIG. 14, a flow chart 1400 illustrates an embodiment of a method provided in accordance with the present invention. A signal is received from the vehicle sensors 140 and 145 (FIG. 1), in which the signal generally indicates the presence of a vehicle in the drive-through (step 1402). The 140 and 145 vehicle sensors transmit the signal to the merchant controller 115 (FIG. 1). In response, merchant controller 115 directs the imaging sampler 160 to focus on and generate an image of the license plate of the vehicle (step 1404). The imaging sampler 160 in turn transmits a signal representing the image to the merchant controller 115. The merchant controller 115 determines from the image a set of license plate characters of the license plate (step 1406). The merchant controller 115 may perform optical character recognition (OCR) on the image of in order to determine the set of license plate characters. OCR is a process in which an image of characters is analyzed to determine the shapes of the characters by detecting patterns of dark and light. Once the shapes are determined, character recognition methods (pattern matching with stored sets of characters) are used to translate the shapes into computer text. Sometimes OCR is done with special readers, but often it is done using a standard imaging sample and specialized software. The merchant controller 115 may also determines the state of registration of the license plate, for example, with reference to the colors of the license plate.
The customer database 424 (FIG. 4) is searched to determine if there is a customer record that corresponds to the set of license plate characters (step 1408). Typically, if the vehicle has never had its license plate scanned as described above, there will be no corresponding customer record. If no customer record exists, then a customer record is created (step 1410). The created customer record will correspond to the set of license plate characters. For example, referring again to the table 700 (FIG. 7), a new record of the customer database 424 may be created and the set of license plate characters may be stored in the field 702 of the record. Transaction data is received (step 1412) and stored in the corresponding customer record (step 1414).
Referring to FIG. 15A, a flow chart 1500 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed when a customer located remotely from the store places an order. The merchant controller 115 (FIG. 1) receives a remote order (step 1502) from the user communication device 110 (FIG. 1). For example, a customer may submit a remote order using a computer to access a web site, or using a telephone to access an interactive voice response unit (“VRU”). The merchant controller 115 also receives from the customer the set of license plate characters (step 1504) to identify the customer when the order is collected. The customer may further specify, for example, an intended time of collection of the order and/or a merchant from which to collect the order if more than one merchant may satisfy the order. In response to the information received from the customer, a record is created in the remote order database 324 (FIG. 3). The record would be identified by the set of license plate characters and would indicate the remote order.
Referring to FIG. 15B, a flow chart 1550 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed when a customer collects a remotely-placed order. The merchant controller 115 determines a set of license plate characters of a customer's vehicle (step 1552) as described above. The remote order database is then searched for a record corresponding to this set of license plate characters (step 1554). If it is determined that there is no such corresponding record (step 1556), then the transaction is processed conventionally (step 1558).
Otherwise, the remotely ordered items are determined from the corresponding record of the remote order database (step 1560). The remotely ordered items are then registered as ordered items (step 1562) as if the customer had placed the order at the drive-through. The credit card account (or other financial account) of the customer, if any, is also determined from the remote order record (step 1564). Alternatively, the account of the customer may be determined by referring to a record of the customer database, if the customer had previously used his credit card account to pay for a transaction. The account is charged (step 1566) (or payment is otherwise rendered) in an amount equal to the purchase price of the order, and the merchant controller outputs a command to assemble the remotely ordered items (step 1568), if necessary, to the kitchen staff in a manner known in the art.
Referring to FIG. 16A, a flow chart 1600 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed when a customer desires to make his current order the “default order”, thereby allowing the merchant to sell him his desired items without specifying those items again. The merchant controller 115 (FIG. 1) determines a set of license plate characters of the customer's vehicle (step 1602) and receives an indication of the items the customer is ordering (step 1604) as described above. The customer is asked if his current order should be his default order (step 1606). The customer responds, and the response is received (step 1608) by, for example, actuating a key on a POS terminal. If the customer response is affirmative (step 1610), then the ordered items are stored as the default order of the customer (step 1612). For example, the corresponding customer record may indicate the default order in the field 710 (FIG. 7). Alternatively, an appropriate record of the default order database 332 (FIG. 3) may be created or adjusted to reflect the default order, as well as any restriction on when the default order would be active. The remainder of the transaction is then processed as described above (step 1614). In an alternate embodiment, each item of the order may be designated as a “default item”, rather than the entire order being designated a “default order”.
Referring to FIG. 16B, a flow chart 1650 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed when a default order is registered as the customer's order. The merchant controller 115 (FIG. 1) determines a set of license plate characters of a customer's vehicle (step 1652) as described above. If the corresponding customer record does not indicate that the customer has a default order (step 1654), then the transaction is processed conventionally (step 1656).
Otherwise, the default order of the customer is determined (step 1658) and the customer is asked whether he would like the default order (step 1660). The default order may be read by the cashier to the customer, and/or the default order may be displayed on the menu board display 135 (FIG. 1). The customer's response is received (step 1662) and if it is determined that the response is affirmative (step 1664) then the items of the default order are registered as ordered items (step 1666).
Referring to FIG. 17, a flow chart 1700 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed when a customer is able to purchase an item for a custom price, which is typically less than the retail price of the item. The merchant controller 115 (FIG. 1) determines a set of license plate characters of a customer's vehicle (step 1702) as described above. If the corresponding customer record does not indicate that the customer has one or more custom prices (step 1704), then the transaction is processed conventionally (step 1706). Otherwise, the corresponding items and custom prices are displayed on the menu board display (step 1708). If the customer chooses to order any of the items having custom prices, then the custom prices are charged rather than the retail prices.
Referring to FIG. 18, a flow chart 1800 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed when a customer has an associated custom menu arrangement. For example, based on past transactions of the customer, the most frequently purchased items may be displayed more prominently (e.g. at the top of the menu board display 135 or centrally located on the menu board display 135).
The merchant controller 115 (FIG. 1) determines a set of license plate characters of a customer's vehicle (step 1802) as described above. If the corresponding customer record does not indicate that the customer has a custom menu arrangement (step 1804), then the transaction is processed conventionally (step 1806). Otherwise, the menu board display displays the items and prices according to the custom arrangement (step 1808).
Referring to FIG. 19, a flow chart 1900 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed to provide an offer to a customer based on his past transactions. For example, based on past transactions of the customer, the most frequently purchased items may be offered if it has not been ordered presently, or an item that has never been purchased may be offered.
The merchant controller 115 (FIG. 1) determines a set of license plate characters of a customer's vehicle (step 1902) as described above. The past transactions of the customer are determined (step 1904), typically by referring to the customer database 424 (FIG. 4). Transaction data is then received (step 1906) as described above. An offer that is based on previously ordered items is then generated (step 1908). For example, if a previously-ordered item does not match any of the ordered items, that previously-ordered item may be offered to the customer. Similarly, the offer may be for an item that has never been ordered. An indication of the offer is output (step 1910), for example by displaying text on a POS terminal which may be read by the cashier. If the offer is accepted (step 1912), then the offered item is added to the order (step 1914). Then, the transaction is processed conventionally (step 1916).
Referring to FIG. 20, a flow chart 2000 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed to determine if a customer is a frequent patron of the merchant or if the customer has rarely or never frequented the merchant. The merchant controller 115 (FIG. 1) determines a set of license plate characters of a customer's vehicle (step 2002) as described above. The merchant controller 115 then determines the number of past transactions (step 2004) that the customer has had with this merchant (step 2004), typically by referring to the customer database 424 (FIG. 4).
If the number of transactions is below a first predetermined threshold (step 2006), then the customer is an infrequent customer, and it would be advantageous to prompt future patronage. Accordingly, the customer may be provided with a bonus (step 2008) such as a coupon redeemable at the merchant. In an alternate embodiment, the customer may be provided with an offer, such as an offer for a supplementary product in exchange for an amount of change due him. If the number of transactions is above a second predetermined threshold (step 2010), then the customer is a frequent customer, and it would be advantageous to reward the customer for his patronage. Accordingly, the customer may be provided with a bonus (step 2012) such as a discount.
In a related embodiment, the number of transactions of the customer and the number of merchants visited by the customer may be determined from the customer record. It can be especially advantageous to determine if and how often the customer has participated in transactions with any of a set of merchants, such as different franchisees of a particular retailer. If the customer has participated in transactions with more than one merchant of the set more than a predetermined number of times, a bonus could be provided to prompt future patronage at one of the merchants. For example, if a customer has participated in transactions with more than one merchant of the group of related franchisees more than three times per month, a bonus could be provided to prompt future patronage at one particular franchisee. Other variations will be apparent to those skilled in the art.
The above-described embodiment is especially advantageous when a set of stores are commonly owned and the owner would like customers to be directed to one of the stores (e.g. the one with the lowest sales). Often, an owner of several stores all within a short distance of the others will find one store to suffer much lower sales than the rest. The owner could assure that customers would be provided with a bonus to prompt future patronage at one, but not the remaining, commonly-owned stores.
Referring to FIG. 21, a flow chart 2100 illustrates an embodiment of a method provided in accordance with the present invention. In particular, the illustrated method is performed to allow a customer to periodically collect items that are complimentary or prepaid. The merchant controller 115 (FIG. 1) determines a set of license plate characters of a customer's vehicle (step 2102) as described above. The merchant controller 115 then determines if the customer is eligible for any complimentary items (step 2104), typically by referring to the appropriate record of the complimentary item database 328 (FIG. 3). For example, the number remaining must be greater than zero and no complimentary item may have been received within the specified time period. If the customer is not eligible, the transaction is processed conventionally (step 2106).
Otherwise, the complimentary item is added free of charge to the order (step 2108), thereby registering the complimentary item as an ordered item. The appropriate record of the complimentary item database 328 is updated (step 2110) to reflect the new number remaining (field 1122) and the new date the complimentary item was last received (step 1124). If desirable, a third party is charged for the complimentary item (step 2112). For example, a set of complimentary items may be purchased for the customer on behalf of a third party who is charged initially or when the complimentary items are received. In another embodiment, the set of complimentary items may have been purchased in advance by the customer. Accordingly, no third party would need to be charged.
Customers may change license plates. For example, a customer may buy another vehicle that has a new set of license plate characters on its license plate. Rather than having a new customer record created for the new set of license plate characters, the customer may associate the new set of license plate characters with the customer record that corresponds to the old set of license plate characters. For example, the new set of license plate characters may be stored in the field 702 (FIG. 7) of the corresponding customer record. The new license plate characters may be entered in a number of ways, such as by the customer via a kiosk or a web site, or by a cashier operating a POS terminal.
The present invention may be used to collect information about customers and their patronage. Such information may in turn be advantageously employed by various merchants to determine “repeat customers”. The above-described databases may be searched to determine, for example, how many customers visit the store more than once per month and how many of the customers that visited the store in the current month had also been to the store last month. In such an embodiment, the imaging scanner and vehicle sensors may be located in an alley through which vehicles must pass to enter a parking lot. Thus, even customers that do not place orders in a drive-through may have their license plates read and processed as described above.
Although the present invention has been described with respect to a preferred embodiment thereof, those skilled in the art will note that various substitutions may be made to those embodiments described herein without departing from the spirit and scope of the present invention.
