============================
As per Worldpay documentation found in here - https://merchants.worldpay.us/docs/index.taf?topic=faq
WorldPay Online Commerce Suite can process VISA, MasterCard, American Express,
Discover, Diners Club and JCB. In order to process Discover credit cards, you need
to apply with Discover for a Discover Merchant account. Once the account is approved,
you must provide the information to your Merchant Bank that processes your MasterCard
and VISA transactions.  After this is confirmed, the final step is to login to
Online Merchant Center, open the Acct Edit/Delete menu, and select the payment option Discover.
