US Patent 11941616 Payment authentication system for electronic commerce transactions

A payment managing system and method for enhancing the security of electronic user payment data can include employing a two factor authentication and keeping e-commerce host system outside the PCI scope. The two-factor authentication can include using a session ID and a one-time token (OTT). The session ID can identify a payment session that is initiated upon initiation of an e-commerce transaction. The payment managing system can provide a computing device initiating the transaction an iFrame to handle input user input data on an information resource. The OTT can be used to tokenize the user input data. The OTT can be included in payment authorization requests sent to the payment managing system. The payment managing system can obtain payment authorization without the user payment data being shared with e-commerce host systems.
