After Engage is activated two new dictionaries called cardDetails and
shopperDetails will be available as part of the
Transaction Object:

}
In the cardDetails dictionary, the fingerprint attribute
is the unique card identifier that lets you track a shopper's payment card across all
purchases. The fingerprint will be available regardless of whether
the transaction was approved or declined.
