Systems and methods of verifying origin of request for payment

A system, comprising:

• a financial institution backend for a financial institution, the financial institution backend executing a financial institution computer program;
• a merchant point of sale device;
• and
• a customer electronic device;
• wherein:
• the financial institution maintains a payment domain and a certificate of domain for a payment domain;
• the financial institution provides a trusted application, wherein the trusted application includes an embedded certificate of domain, and wherein the embedded certificate of domain corresponds to the certificate of domain for the payment domain;
• the financial institution computer program generates a machine-readable code comprising a payment uniform resource locator (URL) embedded therein, wherein:
• the payment URL comprises a pointer to a network location for the financial institution;
• the payment URL maps to the payment domain maintained by the financial institution;
• and
• the payment URL includes a deep-link association with the trusted application;
• the financial institution computer program communicates the machine-readable code to a merchant point of sale device for a merchant;
• the customer electronic device scans the machine-readable code that is displayed by the merchant point of sale device;
• the customer electronic device executes, in response to a user scanning the machine-readable code as part of a transaction, the trusted application via the deep-link association with the trusted application included in the payment URL;
• the financial institution computer program receives, at the payment uniform resource locator and from the trusted application, the embedded certificate of domain;
• the financial institution computer program compares the embedded certificate of domain to the certificate of domain for the payment domain;
• in response to the comparison, the financial institution computer program determines a match between the embedded certificate of domain and the certificate of domain for the payment domain;
• in response to the determination of the match, the financial institution computer program presents, to the customer electronic device, a payment web page;
• the financial institution computer program receives, at the payment web page, payment details from the customer electronic device;
• and
• the financial institution computer program executes the transaction using the payment details.
