  • Patent number: 11227275
    Abstract: A payment processing method involves a server receiving a payee identifier, and linking the payee identifier to a device identifier identifying a payee device. The server receives from a payor device a payment initiation request identifying a specified payment amount and a payor identifier, links a unique token to the specified payment amount and to the payor identifier, and provides the payor device with the token. The token excludes the payor identifier and particulars of the associated payor. The server receives a payment completion request including the payee identifier and the token, and excluding the payment amount, the payor identifier and payor particulars. The server uses the payee identifier to confirm that the payment completion request was signed with the device identifier, uses the payee identifier to locate a payee account, and uses the token to determine the specified payment amount and a payor account associated with the payor identifier.

  • Patent number: 10803516
    Abstract: A method and system for recommending a physical location at which to complete an electronic activity are disclosed. In some examples, the system identifies an incomplete portion of an electronic activity initiated at a first device, and identifies a plurality of candidate locations for completion of the electronic activity based on at least one characteristic of the incomplete portion. When a prior location of the first device is closer to a first one of the candidate locations than to a second one of the candidate locations, the system selects the first candidate location for the completion of the electronic activity and provides activity data characterizing the electronic activity to a second device disposed at the first candidate location.
