  • Publication number: 20250111348
    Abstract: A payment service system (PSS) can receive an identifier and first transaction information, which can include payment card information, from a first merchant system of a first merchant for a first payment transaction with a customer. An association between the identifier and the first transaction information can be stored. The PSS can receive the identifier from a second merchant system of a second merchant for a second payment transaction with the customer in which the customer provided the identifier instead of a payment card. Based at least in part on the identifier and the stored association, the PSS can identify the payment card information and contact information. A confirmation can be transmitted to a customer device using the contact information, and a confirmation response can be received from the customer device. The PSS can execute a transfer of a payment amount to the second merchant.

  • Publication number: 20250111349
    Abstract: A payment service system (PSS) can receive in a first payment transaction between a customer and a first merchant, from a first point-of-sale (POS) device, payment information from a payment instrument and first biometric input captured at the first POS device in association with reading of the payment information. An association between the first biometric input and the payment information can be stored. The PSS can receive, in a second payment transaction, from a second POS device at a second merchant, second biometric input captured at the second POS device. The PSS can identify, based on the second biometric input and the association, without any additional identifier from the customer, the payment information read at the first POS device. The PSS can facilitate the second payment transaction with the payment information read from the payment instrument.

  • Patent number: 12211024
    Abstract: Described is a technology that enables a customer, who uses a payment card in a transaction and further provides an identifier in the same transaction, to use the identifier as a payment mechanism in future transactions. In some embodiments, the technology involves communication between a customer's user device, a payment service system (PSS), and one or more merchant point-of-sale (POS) systems. A merchant POS system collects information in a transaction between the merchant POS system and the customer, including the customer's contact information (e.g., telephone number), and forwards this information to the PSS. The PSS stores the information as an identifier, and the identifier is stored in association with the payment card. In a second transaction, the PSS sends a verification request to the user device based on the identifier (e.g., a text message), and processes the transaction upon confirmation from the customer.

  • Publication number: 20240193507
    Abstract: In some examples, a system uses a first computational model to determine individual merchants that are predicted to receive orders during an upcoming time period. The system determines respective indicated geographic locations of a plurality of delivery agent devices associated with a plurality of delivery agents. Based at least on the first computational model predicting that a first merchant of the individual merchants is predicted to receive an order for the upcoming time period, delivery agent management logic is executed to receive the current locations of the active delivery agents and select a delivery agent to move to a location to be in position for picking up the order that is predicted to be received by the first merchant. The system sends a message to the delivery agent device of the selected delivery agent to instruct the selected delivery agent to move to the location.

  • Patent number: 11934991
    Abstract: In some examples, a computing device sends, to an application on a user device, item information to cause the application to present a user interface including information about items available from a merchant. In response to receiving a user input via the user interface to select an item from the merchant, the computing device determines that a likelihood that the item will be unavailable exceeds a threshold. The computing device sends a communication that causes the application to present a plurality of selectable options to indicate actions to perform when the item is unavailable. The computing device receives a request to place the order for the item, and an indication of the action to perform. In response to receiving a communication from the merchant device indicating that the item is unavailable, the computing device sends an instruction to the merchant device indicating the action to perform.

  • Patent number: 11915170
    Abstract: In some examples, a processor may access past order information for a plurality of merchants to determine, for an upcoming time period, a number of orders predicted to be received by the merchants. The processor may determine geographic locations of delivery agent devices, each associated with a respective delivery agent. The processor may compare, for the upcoming time period, a number of active delivery agents with the number of orders predicted to be received. Based at least on determining a predicted shortage of active delivery agents for the upcoming time period, the processor selects a first delivery agent of the plurality of delivery agents to pick up a first order from a first pickup location of a first merchant and a second order from a second pickup location of a second merchant, and sends a message to a first delivery agent device associated with the first delivery agent.

  • Publication number: 20240046276
    Abstract: Expedited transaction processing using a database of integrated in-store and online transactions is described. First transaction information associated with a first transaction conducted in a physical store of a merchant and second transaction information associated with a second transaction conducted via an online store of the merchant can be received. The first transaction can be processed based at least partly on the first transaction information and a record of the first transaction can be stored in the database. Based at least partly on the record, the second transaction can be processed using at least a portion of the second transaction information by (i) sending, to a card authorization service, the second payment information and (ii) generating an indication that the first payment information was authorized for the first transaction at the physical store. A computing device of the online store can be notified that the second transaction is allowed.

  • Patent number: 11861581
    Abstract: Described is a technology that enables a customer, who uses a payment card in a point-of-sale (POS) transaction and provides a biometric identifier to the merchant, to use the biometric identifier as a payment mechanism in future transactions. In some embodiments, the technology involves communication between a customer's user device, a payment service system (PSS), and one or more merchant POS systems. A merchant POS system collects information around the time or after the time of the POS transaction between the merchant POS system and the customer, including, among others, a biometric identifier of the customer and forwards this information to the PSS. The PSS stores the biometric identifier in association with the payment card used in the transaction. In a second transaction, the customer may provide the biometric and the PSS may process the transaction based at least in part on the identifier without the customer needing to provide a payment card.
