Systems and methods for processing direct electrical energy transfer payments at point of interaction

A method implemented in a payment processing system including a point-of-sale (POS) terminal having one or more processors in communication with a wireless power/communication interface, an energy storage device, a memory device, and a payment network, said method comprising:

• receiving a transaction request from a cardholder device associated with a cardholder;
• determining that the transaction request corresponds to a direct electrical energy transfer transaction, the direct electrical energy transfer transaction involving a purchase of goods or services by the cardholder in exchange for an amount of electrical energy transferrable to a merchant via the cardholder device;
• transmitting a transaction cost of the purchase of goods or services to the cardholder device, the transaction cost including a cash currency value and an electrical energy amount equivalent to the cash currency value;
• receiving payment data from the cardholder device;
• transmitting a payment authorization request message for the direct electrical energy transfer transaction to the payment network for approval, the payment authorization request message including the payment data;
• receiving a payment authorization request response message from the payment network, the payment authorization request message including an approval of the direct electrical energy transfer transaction;
• after receiving approval of the direct electrical energy transfer transaction, receiving, via the wireless power/communication interface, an amount of electrical energy from the cardholder device;
• determining the amount of electrical energy received from the cardholder device;
• storing the amount of electrical energy in the energy storage device;
• and
• conducting the transaction using payment with electrical energy based on the amount of electrical energy received.

A non-transitory computer readable medium including computer-executable instructions that when executed by a computing device having one or more processors in communication with a wireless power/communication interface, an energy storage device, a memory device, and a payment network, cause the computing device to:

• receive a transaction request from a cardholder device associated with a cardholder;
• determine that the transaction request corresponds to a direct electrical energy transfer transaction, the direct electrical energy transfer transaction involving a purchase of goods or services by the cardholder in exchange for an amount of electrical energy transferrable to a merchant via the cardholder device;
• transmit a transaction cost of the purchase of goods or services to the cardholder device, the transaction cost including a cash currency value and an electrical energy amount equivalent to the cash currency value;
• receive payment data from the cardholder device;
• transmit a payment authorization request message for the direct electrical energy transfer transaction to the payment network for approval, the payment authorization request message including the payment data;
• receive a payment authorization request response message from the payment network, the payment authorization request message including an approval of the direct electrical energy transfer transaction;
• after receiving approval of the direct electrical energy transfer transaction, receive, via the wireless power/communication interface, an amount of electrical energy from the cardholder device;
• determine the amount of electrical energy received from the cardholder device;
• store the amount of electrical energy in the energy storage device;
• and
• conduct the transaction using payment with electrical energy based on the amount of electrical energy received.
