  • Patent number: 11080771
    Abstract: An online shopping concierge service allows shoppers to purchase items on behalf of customers and checkout using a mobile application, circumventing traditional point-of-sale check-out systems. A customer places an order using a mobile application or website associated with the online shopping concierge service. The online shopping concierge service charges a payment instrument of the customer in the value of the selected items. The system transmits the order to a shopper, who receives an order for fulfillment on a mobile device. The shopper collects and scans items using a mobile application. The mobile application transmits an identification of the items for purchase and their total cost to the online shopping concierge service, which transmits payment to the retailer. Alternatively, the mobile application encodes an identification of the items for purchase into an encoded image, which is scanned by a cashier, allowing the shopper to complete an accelerated check-out.

  • Patent number: 10817926
    Abstract: An online concierge system receives an order from a customer with a list of items and allocates the order to a retailer at which the items can be picked. The retailer is associated with a payment processing system having a corresponding tokenization process. The online concierge system uses the tokenization process for the retailer to generate a payment token for the customer based on stored payment data and transmits the payment token to the payment processing system. The online concierge system determines a first payment amount from the customer to the retailer based on items picked at the retailer and a second payment amount from the retailer to the online concierge system. The payment processing system charges the customer a sum of the first payment amount and the second payment amount using the payment token. The online concierge system receives the second payment amount from the payment processing system.
