Abstract

A method for encapsulating transaction instrument information in a transaction includes storing, in association with a first transaction and by a processor of the primary transaction processor server, payment data associated with a payment instrument used to settle a cost of a first transaction. The primary transaction processor server transmits the transaction data to a payment network processor. The primary transaction processor server receives an authorization package from the payment network processor that includes a cryptograph and a first network token. The processor of the primary transaction processor server generates a secondary token, and stores a correlation record to a computer-readable memory. The correlation record associates the secondary token to a second object stored by the primary transaction processor. The processor of the primary transaction processor server transmits a second transaction package including at least one of the network token and the secondary token to a merchant device.
