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, transaction data associated with a transaction instrument for a first transaction. The primary transaction processor server transmits the transaction data to a payment network processor, and receives an authorization package in response that includes a cryptograph and a first network token. The primary transaction processor server generates a second token that includes a changeable alpha-numeric string associated with the transaction instrument used in the first transaction, and transmits the second token to a merchant device. The second token indicates that a transaction associated with the second token is either i) a customer-initiated transaction or ii) a merchant-initiated transaction. The secondary transaction processor may approve or reject a transaction using the second token without a cryptogram.
