ALTERNATIVE ACCOUNT IDENTIFIER

摘要

Payment instrument data is received in connection with a transaction, the data including an alternative primary account number (PAN) and an account identifier. A permanent PAN of an account is identified that is based on the account identifier. An alternative PAN associated with the permanent PAN is derived to determine whether the received alternative PAN matches the derived alternative PAN associated with the permanent PAN.
