Question:   "I noticed that the ECF saves only the last 4-digits of the credit card number, I need to save more, how do I do this?"

Answer:  This is done in Commerce Manager.   Go to Configuration > Site Settings > Global Settings.  There, half way down the screen you will see the option to "Keep Credit Card Info".   By choosing "yes", you will be storing the credit card information in the database, otherwise, it is discarded upon completion of the order.

Note:  The storing of credit card information is done securely as it is encrypted.
