The Card Information window—
Payment Details view is where you can enter information about how a customer usually pays you. The method and related information you enter will appear on payment transactions for the customer. Note that you can change the payment information on individual transactions before you record the transaction.
If you process credit card payments, there are two additional fields that are important for the Address Verification Service (AVS): Address and ZIP. If you always physically have this customer’s credit card and swipe it for electronic approval, the entry in this field is for your information only. If you enter sales without the card, this information is essential.
The information you enter here appears in the Applied Payment Details window for a Sales or Receive Money transaction. If the fields in the Applied Payment Details window are blank or if the customer is using a different credit card, enter the new information. If you select the Update Customer Card with Payment Details field, the information you enter in the Applied Payment Details window appears in the Customer view of the Card Information window.
