US Patent 10579999 Network payment tokenization for processing payment transactions

The present disclosure relates to systems, methods, and devices for network payment tokenization for processing payment transactions. In particular, the message system allows a consumer to initiate a payment transaction with a merchant. For example, one or more implementations involve identifying a payment authorization number associated with a user account and sending a request for a payment token to a card network system associated with the payment authorization number. One or more embodiments receive a network payment token representing the payment authorization number and a single-use cryptogram corresponding to the payment transaction. Additionally, one or more embodiments generate and send a payment transaction initiation message including the network payment token and single-use cryptogram to the merchant for processing the payment transaction.
