Thanks Alan, thats true, isn't it? Maybe the name AND the last 4 digits
since the customer's name on the card may not be as they provide it to the
restaurant manager. (Jim instead of James, for instance). This way I can
do an indexed query on the last four digits and display the cardholders name
in a list to the user...

Thanks again,
