I'd like to show the last 4 digits of CC# in the confirmation email. So far I have managed to use uc_credit_display_number as follow
print uc_credit_display_number($order->payment_details['cc_number'], false);
Perhaps it already exists (I could not find a list of available tokens . If not, is there a way to make a token out of $order->payment_details['cc_number']?
