-This module is for verifying I<real world> B<credit cards>.  It is B<NOT> a
-pedantic implementation of the ISO 7812 standard, a general-purpose LUHN
-implementation, or intended for use with "creditcard-like account numbers".
+Discover requires some cards processed on its network to display "PayPal"
+on receipts instead of "Discover".  The receipt_cardtype() subroutine will
+return "PayPal card" for these cards only, and otherwise the same output as
+cardtype().
 
-=head1 AUTHOR
+Use this for receipt display/printing only.
