Client computer systems can add authenticity to electronic payment requests through use of software license keys. In one implementation, for example, a payment request originating from a requestor (e.g., client computer system, point of sale terminal) sends one or more license key identifiers to a payment validating entity along with the payment details of the requested transaction. In addition to reviewing the payment transaction request and payment details for fraud, one or more payment validating entities can also review the one or more license key identifiers to determine if the request originates from as client computer system using valid software, or using potentially invalid or otherwise pirated software. In one implementation, the payment validating entities can deny a transaction originating from software from which validity cannot be determined. The payment validating entities can also, or alternatively, store information about the requestor for subsequent reporting purposes.
