US Patent 11182793 Systems and methods for transaction account tokenization

A system may receive a request for a payment payload for a payment transaction with the request including a token and a transaction amount. The token may identify a transaction account for use in the payment transaction. The system may assess the risk of fraud associated with the transaction account and the payment transaction. The system may return the payment payload in response to a favorable risk assessment. The payment payload may be passed to a merchant and from the merchant to a payment network for evaluation. The payment transaction may be approved or declined based on the contents of received payment payload matching the contents of a generated payment payload.
