Abstract:
This is a system to assist shoppers through a handheld wireless communications device which is Bluetooth-enabled (as an example) (a registered trademark), connected to a barcode reader to scan Universal Product Code (UPC) barcodes on items in the store. The shopper is required to login to the store&#39;s shopping system using this device once a personal account has created. While shopping, scan the items, view their prices and running total and finally complete the purchase. This system is also capable of (as an example) consolidating a personal shopping list created remotely through vendor&#39;s web site or stored on the personal communication device and the shopping cart to help and enhance the shopping experience.

Description:
[0001]    This is a Cont. of another Accelerated Exam. application Ser. No. 12/020,546, filed Jan. 27, 2008, to issued in November 2008, as a US Patent, with the same title, inventors, and assignee, IBM. 
       BACKGROUND OF THE INVENTION 
       [0002]    Shoppers frequently are not sure of the price of an item on the shelf. It is not clear exactly which item is being referred to for sale prices, whether it is taxable, and the price that actually shows at the register is frequently a complete surprise. In order to get an idea of the cost of your purchases, shoppers bring calculators to the grocery store in order to stay within their budget. Others remove items during checkout after the price is determined. 
         [0003]    Between long checkout lines, and distraught shoppers, the shopping experience has become less enjoyable than it could be. This proposed system tries to address these problems and perform as an assistant to the shopper enhancing the experience and reducing the checkout time. 
       SUMMARY OF THE INVENTION 
       [0004]    When a shopper enters a store or a mall that uses this technology, he is handed a Bluetooth (Reg. trademark) enabled wireless device with a barcode reader that can scan Universal Product Code (UPC) barcodes printed on items in the store. The shopper will then be required to login to the store&#39;s shopping system using the provided device or personal cell phone if the barcode reader could be connected to the personal device. This system is preferably configured to operate with a personal account that was previously setup to begin shopping. 
         [0005]    Through the provided device or the personal cell phone shoppers are presented with several primary functions such as “Price Check”, “Purchase Item” and “Check out” and several secondary functions such as “Show Cart Detail”, “Show Stock Detail”, “Remove Items” and logout. If “Check Out” is selected, shopping cart items are browsed and edited and verified and finally a receipt is printed which could be used with the register checkout counter&#39;s receipt for final verification. If “Price Check” is selected, the final price of the item is displayed which will include any discounts based on a sale price, volume purchase or personal contract with the vendor. If “Purchase Item” is selected, a cart is created if it does not already exist, items are added to the cart as it is scanned and running totals are calculated and presented. 
         [0006]    Other secondary function proposed by this system are: removing items from the cart, showing the cart details, showing the inventory of the store for the scanned item and finally logout option to return the device back to the store. 
         [0007]    Another proposed functionality of this system could be to combine a shopping list that is already stored on the user&#39;s personal wireless communication device with the cart items and display the items that are missing from the shopping cart, if the shopper&#39;s personal wireless communications device is used. This capability could further enhanced, if user could create a shopping list on the vendor&#39;s borrowed communication device or if the shopper could create a shopping list through the vendor&#39;s web site remotely before the shopping begins.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0013]    One of the embodiments is a system and method of shopping using wireless communication which could be used in a shopping center or mall (as an example). This method is comprised of the following steps (as an example): a shopper is using a wireless device to communicate with a network. 
         [0014]    The shopper logs in to a store shopping system network, using a cellular or mobile phone. The shopper scans the bar code or universal symbol printed on a first object using the wireless device, where the first bar code or universal symbol is indicating price, tax, and information about the first object. The shopper adds the first object to the first shopping cart. The shopper removes a second object from the first shopping cart, and she/he calculates a total value of the first shopping cart. She/he is establishing a first shopping list as an alternative to the first shopping cart, and is calculating a total value of the shopping list (while storing the first shopping cart and the first shopping list on the wireless device and the cellular or mobile phone). 
         [0015]    The shopper scans a second bar code or universal symbol printed on a piece of paper or substrate, using the wireless device from a remote location with respect to the physical location of the shopping center or mall. 
         [0016]    The second bar code or universal symbol indicates price, tax, and information about a third object. The shopper adds the third object to a virtual shopping cart. The shopper removes a fourth object from the virtual shopping cart, calculating a total value of the virtual shopping cart, establishing a virtual shopping list as an alternative to the virtual shopping cart, calculating a total value of the virtual shopping list and stores the virtual shopping cart and the virtual shopping list on the wireless device and the cellular or mobile phone. 
         [0017]    Some of the capabilities of this system are, but not limited to: combining the data from the virtual shopping cart and the virtual shopping list on the wireless device and cellular or mobile phone with the data from the first shopping cart and the first shopping list on the wireless device and the cellular or mobile phone. It is also capable of checking the available inventory at the store shopping system, checking the available sales and coupons at the store shopping system, displaying all the objects selected by the shopper, comparing all the objects selected by the shopper with each other and with a database. It is also capable of receiving a discount based on a volume of purchase, obtaining a contract between the store shopping system and the shopper, receiving a discount based on predetermined prices given in the contract between the store shopping system and the shopper, where the contract further comprises a pre-approved list of items and pre-approved credit. ( 410 ,  412 ,  414 ) Also checking out objects from the store shopping system, returning a fifth object to the store shopping system and receiving a receipt from the store&#39;s shopping system. 
         [0018]    Another embodiment of this system is depicted in  FIG. 1-5  and is as follows: A shopper walks into a store and mall and uses a wireless device such as a cell phone or a vendor provided equipment and logs into the providers network using and existing personal account ( FIG. 1 , step  110 ). The main functionality presented to the customer could be the following but not limited to: “Customer Checkout”, “Price Check”, “Purchase Item” and “Other Actions”. “Other actions” could be the group of the following options but not limited to: “Remove Item”, “Show Cart Detail”, “Show Stock Detail” and “Log Out”. 
         [0019]    If “Customer Checkout” option is selected ( FIG. 1 , step  112 ), customer is instructed to proceed to the checkout ( FIG. 3 , step  310 ), cart items are presented to the customer in step  312  of  FIG. 3  for review and verification. If cart contents is verified ( FIG. 3 , step  314 ), a receipt is printed, customer is logged out of the network and process ends. This would be the verification of the purchase and account and the quick check at the checkout counter is to flag items that are not in the cart or not in the list which could be added or removed quickly. If the cart contents is not verified ( FIG. 3  step  314 ), cart contents can be edited ( FIG. 3 , step  316 ) and items added and removed. At this stage customer is presented with “Purchase Item” option, which will be described in the following paragraphs (with a receipt option ( 318 )). 
         [0020]    If “Price Check” option is selected ( FIG. 1 , step  114 ), Contracts database, discounted items list, quantity purchase discount or any other special pricing schedules are consulted to provide the final discounted cost of the purchase of the item to the customer. If no special price was found and no special contract for this customer was located, the normal store catalog is consulted and the price is displayed. At this stage, the “Purchase Item” option is displayed to the customer and is discussed in the next paragraph. 
         [0021]    If “Purchase Item” option is selected ( FIG. 1 , step  116 ), the system verifies that a cart for this purchase exists ( FIG. 5 , step  510 ). If a shopping cart does not exit, it is created ( 512 ) and then the item is added to this cart ( FIG. 5 , step  514 ). If the shopping cart already exists, this item is simply added to the existing shopping cart. At this stage, customer is presented with the “Purchase Item” option again for scanning of the next barcode. This loop continues until the customer is completed with scanning and selects no for the last “Purchase Item” option which will then presented with “Other Actions” option which is discussed in the next paragraph. 
         [0022]    “Other Actions” option is presented in  FIG. 1  step  118 , once the customer selects “No” for the “Purchase Item” option. At this stage, if the customer selects “No” again to this option, the main option menu is presented with “Customer Checkout” option at the top. If customer selects “Yes” for “Other Actions” option, the second set of options is presented which could be the following and not limited to: “Remove Item”, “Show Cart Detail”, “Show Stock Detail” and “Log Out” ( FIG. 2 ). 
         [0023]    If “Remove Item” option is selected ( FIG. 2 , step  210 ), the current cart item is removed from the list ( FIG. 2 , Step  212 ), cart item list is updated and customer is presented with “Other Actions” option again. 
         [0024]    If “Show Cart Detail” option is selected ( FIG. 2 , step  214 ), shopping cart items detail is presented ( FIG. 2 , step  216 ) and customer can scroll through the list of the shopping cart and view the details and prices for each item until the end of the list is reached and customer is again presented with “Other Actions” option. Exiting this mode could be done simply by reaching the end of the list or hitting a special function key such as ESC, left or right arrows or any other special key. If the customer has already created a shopping list remotely through the vendor&#39;s web site or on its personal communication device, this verification of the cart which is the consolidated list could show the items that are missing and not in the shopping cart and must be shopped. 
         [0025]    If “Show Stock detail” option is selected ( FIG. 2 , step  218 , store&#39;s inventory list is presented and customer can view the detail of items in the inventory. Once the end of the list is reached, customer is again presented with “Other Actions” options. Exiting this mode could be done simply by reaching the end of the list or hitting a special function key such as ESC, left or right arrows or any other special key. ( 220 ) 
         [0026]    If the “Log Out” option is presented ( FIG. 2 , step  222 ), customer has an option of simply accepting (selecting “Yes”), which terminates the connection and logs the customer out and wireless device is ready for the next use. If “No” is selected, “Other Action” option is again presented and customer can continue.
