In-store mobile payment

## Abstract

An in-store mobile payment system and method can facilitate the use of a user's mobile device to facilitate payment for products purchased at a store. The user can take a picture of a product being purchased or can take a picture of a bar code for the product. The picture can be taken with the user's mobile device and can be used to identify the product. A payment provider can provide a unique PIN code for the transaction. The user can enter the PIN code into a keypad of the merchant and/or can swipe a card with a card reader of the merchant to complete the transaction. Thus, the user can avoid the inconvenience of waiting in line at a checkout counter and the merchant can reduce the store's overhead by eliminating at least some checkout counters and checkout clerks.

## Background
BACKGROUND
Technical Field
The present disclosure generally relates to electronic commerce and, more particularly, relates to a method and system for facilitating in-store purchasing using a mobile device.
Related Art
Various methods are commonly used for making in-store purchases. For example, products to be purchased can be brought by the customer to a checkout counter. At the checkout counter, a clerk can scan the products and accept payment. However, such a contemporary checkout can be slow and inconvenient. Often, a customer must wait in a line to reach the checkout counter.
In an attempt to overcome the disadvantages associated with such a contemporary checkout, some stores now provide self-service customer checkout terminals. According to the self-service customer checkout process, a customer scans the purchased items and then uses an automated system to pay for the purchased items. Often, waiting in line can be avoided because there are typically a sufficient number of self-service customer checkout terminals to provide substantially immediate access to customers. More self-service customer checkout terminals than contemporary checkout counters can be used because self-service customer checkout terminals require much less attention by store personnel and are therefore much less labor intensive.
However, many customers are unfamiliar and uncomfortable with self-service customer checkout terminals. Such customers are reluctant to use the self-service customer checkout terminals and therefore use the contemporary checkout counters, thus increasing the length of the line and wait time for the contemporary checkout counters. As such, it is desirable to provide an improved system for facilitating in-store payment.
SUMMARY
According to an embodiment, methods and systems are provided for employing a user's mobile device to facilitate payment for products purchased at a store. The user can take a picture of a product being purchased or can take a picture of a bar code for the product. The picture can be taken with the user's mobile device and the picture can be used to provide a product identification. A payment provider can use the product identification, combined with other information, to provide a unique PIN code for the transaction. The user can enter the PIN code into a keypad of the merchant and/or can swipe a card with a card reader of the merchant to complete the transaction.
According to an embodiment, a system can comprise a payment server having a memory and one or more processors. The memory can store account information for a user in a user account. The account information can include a user identification. The processor(s) can receive a communication from a mobile device of the user including the user identification, a store identification for a store where the user intends to make the purchase, and a product identification for the product which the user intends to purchase. The processor(s) can access the user account and verify, from the account information, that the user is authorized to purchase the product. The processor(s) can send a communication to the user and/or the merchant authorizing the purchase if the user is authorized to purchase the product. The communication can include a PIN code of the transaction.
According to an embodiment, the processor(s) can run a batch process to facilitate payment for the user's purchase to the store. The batch process can facilitate payment for a plurality of users to a plurality of stores. The batch process can be run at the end of a day, week, or month, for example. The batch process can be run, for example, on the payment server. The batch process can be run by a billing service.
According to an embodiment, the processor(s) can send a communication to the mobile device including a request that the user verify a desire to purchase the product, receive a communication from the user verifying that the user desires to purchase the product, and send a communication to the user authorizing the purchase only if the communication from the user verifying that the user desires to purchase the product is received.
According to an embodiment, the product identification can be a picture of the product. According to an embodiment, the product identification can be a picture of a bar code of the product. In either instance, the processor(s) can be operable to identify the product from the picture. The picture can be taken with a mobile device of the user.
According to an embodiment, the processor(s) can verify that a card of the user was swiped at the store, verify that the PIN code of the transaction was entered at the store, and include payment for the product in the batch process only if the card was swiped at the store and/or the PIN code was entered at the store.

DETAILED DESCRIPTION
An in-store mobile payment system and method can facilitate the use of a mobile device to provide payment for products purchased at a store, according to an embodiment. With the mobile device, a user can take a picture of a product being purchased or can take a picture of a bar code for the product. The picture can be used by the mobile device, a merchant device, a payment server, or the like to identify the product. Identifying the product can include determining a stock keeping unit (SKU) for the product.
A payment provider can act as an agent between the store, e.g., the point of sale, and the shopper. The payment provider can provide a unique PIN code for the transaction. The PIN code can be generated from the SKU, an identification of the user (e.g., a user ID), and/or an identification of the store (e.g., a store ID). The user can enter the PIN code into a keypad of the merchant and/or can swipe a card with a card reader of the merchant to complete the transaction. The user does not need to purchase the product via a contemporary checkout counter. Thus, the user can avoid the inconvenience of waiting in line at a checkout counter and the merchant can reduce the store's overhead by eliminating the expense associated with at least some checkout counters and checkout clerks.
FIG. 1 is a block diagram of an in-store mobile payment system, according to an embodiment. The system can include a merchant device 110. The merchant device 110 can be a merchant checkout terminal, a computer, a smart phone, a computing tablet, and/or a server, for example. The merchant device 110 can include a memory 111, a processor 112, a card reader 113, and a keypad 114.
The system can include a mobile device 120. The mobile device 120 can be carried by the user. The mobile device 120 can be a cellular telephone, a smart telephone, a hand held computer, or a tablet computer, for example. The mobile device can include a processor 121, a memory 122, a global positioning system (GPS) 123, and a camera 124.
The memory 122 can store a software or firmware program or application, e.g., an in-store payment app 126, for the in-store mobile payment system and the app 126 can be executable via the processor 121. The memory can store a digital wallet 127 for the user. The digital wallet 127 can store and retrieve information regarding the user's credit, debit, or payment provider account. This information can be used in making the purchase.
The app 126 can have a presentation layer, a communication layer, and the digital wallet 127. The presentation layer can facilitate application presentation. The presentation layer can facilitate image processing, such as to do machine vision and/or barcode scanning/decoding. The communication layer can facilitate communication between the user device 120 and the payment server 130. The communication layer can facilitate communication between the user device 120 and the merchant device 110.
The system can include a payment server 130. The payment server 130 can be a server of a payment provider, such as Paypal, Inc. The payment server 130 can be a single server or can be a plurality of servers. The payment server 130 can include a processor 131 and a memory 132. The memory 132 can store a user account 133 and a merchant account 134.
The memory 132 can store a user account 133 for each user that subscribes to the payment server 130. The user account 133 can contain information such as a user ID, a credit limit, a spending limit, a balance, and a purchase history. The memory 132 can store a merchant account 134 for each merchant that subscribes to the payment server 130. The merchant account can contain information such as a merchant ID and a transaction history.
The processor 131 and the memory 132 can cooperate to provide the in-store mobile system described herein. The merchant device 110, the mobile device 120, and the payment server 130 can communicate with one another via a network, such as the Internet 140. The merchant device 110, the mobile device 120, and the payment server 130 can communicate with one another via a plurality of networks, such as local area networks (LANs), wide area networks (WANs), cellular telephone networks, and the like.
FIG. 2 is a block diagram showing some functions for the system for in-store mobile payment, according to an embodiment. Once a user is in a store 151 and has selected one or more products for purchase, then the user can initiate in-store mobile payment. For example, the user can select an Apple iPad for purchase. The user can initiate in-store payment by starting the app 126 and then imaging the Apple iPad or its bar code, as shown in step 152. If there is a bar code on the Apple iPad, its packaging, or its in-store display, then the bar code can be imaged (either instead of imaging the Apple iPad or in addition thereto). The image can be taken with the camera 124 of the user device 120. Thus, for example, the user can start the in-store payment app 126 on the user's cellular telephone and can image the Apple iPad and/or the barcode for the Apple iPad using the user's cellular telephone.
The image or information representative of the image (such as the camera's stock keeping unit (SKU)) can be communicated from the user device 120 to the payment server 130. Thus, the app 126 can determine an identification of the product. The app 126 of user device 120 can perform image recognition to determine that the image is an image of an Apple iPad. If the app 126 cannot determine the identification of the product or needs further information to do so, then the app 126 can query the user.
For example, the app 126 may be able to determine that the image is of an Apple iPad, but may be unable to determine the model of the Apple iPad. In this instance, the app 126 can query the user by presenting the user with the models of Apple iPad which are sold by the store and asking the user to select the one of these models that is being purchased. By imaging the bar code, such ambiguity and further clarification of the identity of the product being purchased can be avoided.
Image recognition or decoding of the barcode can be done by the app 126 in the user device 120, by the merchant device 110, by the payment server 130, or by any other device at any location. Image recognition or decoding of the barcode can provide an SKU which can be communicated from the user device 120 or the merchant device 110 (from wherever the image recognition or decoding was performed) to the payment server 130. The SKU can be communicated from the user device 120 or the merchant device 130 to the payment server 130 via the Internet 140, for example.
The user device 120 can also communicate information representative of the store ID to the payment server. The store ID can be obtained by the user by imaging a barcode, sign, display or any other indicia representative of the store ID. The store ID can be communicated from the merchant device 110 or from another device of the merchant to the user device 110 via a wireless network, WiFi, or Bluetooth, for example.
The store ID can be obtained by geo-location as shown in step 152. For example, the store ID can be obtained by using the GPS 123 of the user device 120. A GPS location provided by the GPS 123 of the user device can be used by the app 126 or by the payment server 130 to determine the store ID. For example, the app 126 can reference a database of GPS locations and store ID's that are stored in the memory 122 of the mobile device 120. The store ID can be communicated from the user device 120 to the payment server 130 via the Internet 140, for example.
After receiving the communication from the user device 120, the payment server 130 can access the user account 133 and determine if the user is authorized to make the purchase. For example, the payment server 130 can verify that the user has not exceeded a spending or credit limit (taking into account the proposed purchase) and that the store is one for which purchases are authorized. If purchase is authorized, then the payment server 130 can send a communication to the mobile device 120 and/or the merchant device 110. The communication can optionally include the PIN code of the transaction, which can be numbers, letters, symbols, or a combination thereof. The PIN code can optionally provide an added layer of securing and is not necessarily required.
The PIN code can be sent from the payment server 130 to the mobile device 120. The PIN code can be displayed on a screen of the mobile device 120. The PIN code can be read off of the screen and entered, such as by the user, into the merchant device 110 via the keypad 114. The PIN code can be transmitted from either the payment server 130 or the mobile device 120 to the merchant device 110 to avoid having the user manually enter the PIN code into the merchant device 110. According to an embodiment, the PIN code entered by the user must match the PIN code provided by the payment server 130.
The PIN code can be constructed from information regarding the store, the user, and/or the purchased product(s). For example, the PIN can be constructed from or can contain information representative of the store ID, the user ID, and the SKU of all of the products being purchased by the user during this particular transaction. For example, the PIN code can be a hash of information regarding the store, the user, and/or the purchased product(s). In another embodiment, the PIN code can be a randomly generated code associated with the transaction. The PIN code can be generated by the processor 131 of the payment server 130. The PIN code can function to inform the merchant/merchant device 110 that the purchase transaction is authorized. The PIN code can contain or can define an authorization code that informs the merchant/merchant device 110 that the purchase transaction is authorized. Optionally, use of the PIN code can be omitted.
A receipt for the purchase can be printed and given to the user and/or can be communicated from the merchant device 110 to the user device 120, as shown in step 153. For example, an electronic receipt can be communicated to and stored in the digital wallet 127 of the mobile device 120.
Optionally, a credit card or a payment provider card can be swiped via the card reader 113 of the merchant device 110, as indicated in step 155. The payment provider card can be a card of the user or a card of the store. The payment provider card can belong to either the user or the store.
The card can provide further evidence that the transaction is authorized, e.g., not fraudulent. The card can optionally store information regarding the user, the store, the purchase transaction, and/or previous transactions. The payment provider can match information from the card with transaction details to determine if the transaction is authorized. For example, the payment provider can determine if the user name on the card matches the name of the user making the purchase. Alternatively, the card can belong the merchant and can merely provide an identification of the merchant, e.g., a store ID.
The digital wallet 127 can contain an electronic card, e.g., information representative of a credit card, debit card, or payment provider card. Information from the digital wallet 127 can be used instead of or in addition to the credit card. The information can be communicated from the digital wallet 127 to the merchant device 110 via a local area network (LAN, Bluetooth, infrared (IR) communication, or in any other manner. The information can be displayed on a screen of the mobile device 120 and scanned into the merchant device therefrom. For example, the digital wallet 127 can contain an electronic card having an account number, a user name, an expiration date, and any other desired information. The information of the electronic card can be displayed on the screed of the mobile device and can be captured by a camera of the merchant or can otherwise be communicated to the merchant and/or the payment provider.
During a later batch process, the payment server 130 and/or a billing service 208 can facilitate payment for the purchased product(s). For example, the payment server 130 can cooperate with the billing service 158 to transfer money from a payment provider account to an account of the merchant who owns the store 151, as indicated in step 157.
FIG. 3 is a flow chart showing a method for in-store mobile payment, according to an embodiment. The user can take a picture of a product being purchased and/or a bar code of the product being purchase, as shown in step 201. The picture can be used to identify the product. For example, the picture can be used by the mobile device 120, the payment server 130, the merchant device 110, or any other device to determine an SKU or other identification for the product. As discussed herein, products can be recognized and associated with the SKU via the use of machine vision, the bar code, or any other identifying characteristic or mechanism. If the picture is inadequate to identify the product, then the user can enter information into the user device to identify or help identify the product.
For example, the image can be communicated to the payment server 130, as shown in step 202. A processor 131 of the payment server can run a machine vision recognition algorithm on the image if the image is an image of the product being purchased. If the image is an image of the barcode of the product being purchased, then the payment server 130 can run a barcode decoding program on the barcode.
The user can be prompted by the app 126 to pay for the product(s) being purchased. For example, after the products have all been properly identified by the in-store mobile payment system, then the user can be asked to begin the payment process. The user can begin the payment process by selecting “Yes” to a question displayed on the mobile device 120 such as “Pay for purchases now?”
The payment server 130 can verify that the user is authorized to purchase the product, as shown in step 203. The payment server 130 can check the user account 133 to obtain information that is indicative of the user's authorization to purchase the product. For example, the user account 113 can contain an account record that indicates whether or not the user is in good standing with the payment provided, the user's credit limit, whether or not the merchant subscribes to the payment provider, and the like. The payment server 130 can use such information to determine whether or not the user is to be authorized to make the purchase.
The payment server 130 can verify that the user desires to purchase the product, as shown in step 204. This can be done by the payment server 130 communicating a query to the user. The query can ask the user to verify the user's desire to make the purchase and can include a total price for the purchase.
The payment server 130 can communicate a unique PIN code of the payment transaction to the user, as shown in step 205. This can be the PIN code discussed above. Thus, the PIN code can be used by the merchant to verify that the payment service will pay the merchant for the product.
The user can swipe a credit card or payment provider card and enter the PIN code at the store 201, as indicated in step 206. The card can be swiped via card reader 113. The PIN code can be entered via the keypad 114. Payment for the purchased can be authorized by the payment server 130 in response to receipt of the picture, upon entry of the PIN, upon swiping of the card, or when any combination of these steps has been completed.
The store 151 can issue a receipt to the user, as shown in step 207. The receipt can be a paper receipt or an electronic receipt, as discussed herein.
The payment server can run a batch process to pay the store, as shown in step 208. Both the user and the store can subscribe to the same payment provider. The user and the store can subscribe to different payment providers.
FIG. 4 is a flow chart showing operation of the app 126 of the method for in-store mobile payment, according to an embodiment. A presentation layer of the app 126 can provide the user with a graphical user interface, as shown in step 301. Alternatively, the user can be presented with a text interface. From the user interface, the user can make a selection to take a picture of the product or barcode. Two different options can be presented to the user. For example, the user can select either “Take a picture of the product” or “Take a Picture of the Barcode”, such as from a drop down menu. The app 126 can facilitate imaging of the product or barcode, as shown in step 302.
The app 126 can process the image to identify the product, as discussed in step 303. Alternatively, the payment server 130, merchant device 110, or any other device can process the image to identify the product.
The app 126 can communicate with the payment server 130, as indicated in step 304. For example, the app 126 can communicate the image of the product or barcode to the server 130 for processing thereof.
