Systems, methods, and interfaces to facilitate use of a retail point of sale machine to fund an electronic payment pending with an electronic payment system

A system comprising:

• a retail point of sale (POS) machine that includes at least one of a physical currency payment acceptor, a card payment acceptor, or a user interface, that is communicatively coupled, by way of a network, to a payment funding system communicatively coupled to an electronic payment system, and that:
• receives user input representative of a transaction identifier;
• sends data representative of the transaction identifier to the payment funding system for use by the payment funding system to verify that the transaction identifier corresponds to a pending electronic payment in the electronic payment system that is to be made to a third party;
• receives, from the payment funding system, data representative of information about the pending electronic payment that corresponds to the transaction identifier, the information indicating an amount to fund the pending electronic payment;
• presents the information about the pending electronic payment to a user of the POS machine;
• receives the amount to fund the pending electronic payment by way of at least one of the user inserting physical currency into the physical currency payment acceptor of the POS machine, the user providing a card with respect to the card payment acceptor of the POS machine, or the user interacting with the user interface of the POS machine to provide the amount from an account of the user;
• and
• sends, to the payment funding system, a confirmation indicating that the amount to fund the pending electronic payment to the third party has been received by the POS machine.

A method comprising:

• receiving, by a computer-implemented system and from a retail point of sale (POS) machine, data representative of a transaction identifier received by way of user input at the POS machine, the POS machine including at least one of a physical currency payment acceptor, a card payment acceptor, or a user interface;
• using, by the computer-implemented system, the transaction identifier to query an electronic payment system;
• receiving, by the computer-implemented system and from the electronic payment system in response to the query, data representative of a pending electronic payment that is to be made to a third party, that is associated with the transaction identifier, and that is awaiting funding;
• sending, by the computer-implemented system and to the POS machine, data representative of information about the pending electronic payment, the information indicating an amount to fund the pending electronic payment;
• receiving, by the computer-implemented system and from the POS machine, a confirmation that the POS machine has received the amount to fund the pending electronic payment by way of at least one of a user inserting physical currency into the physical currency payment acceptor of the POS machine, the user providing a card with respect to the card payment acceptor of the POS machine, or the user interacting with the user interface of the POS machine to provide the amount from an account of the user;
• notifying, by the computer-implemented system, the electronic payment system that the pending electronic payment has been funded;
• and
• facilitating providing, by the computer-implemented system to the third party, the amount that was provided to fund the pending electronic payment by way of the user interacting with the POS machine.
