US Patent 11657380 Charge splitting across multiple payment systems

A consumer may initiate a transaction using a transaction account. The transaction account issuer may transmit a notification to the consumer that the transaction has been authorized. The consumer may select requestees with whom to split the transaction. The transaction account issuer may transmit instructions via APIs to peer-to-peer payment systems to request payment from the requestees. The peer-to-peer payment systems may transfer the payment to the transaction account issuer, and the transaction account issuer may apply to payment to the consumer's transaction account.
