This WordPress payment module is designed for making credit card payments through Millennium Bank (Greece).
This payment gateway uses the redirect method where the user is redirected to the processing site (Millennium Bank) to make the actual payment.
After payment verification, Millennium Bank notifies the merchant's e-commerce site and returns the customer back to it. This process is transparent for the customer. The merchant can then connect to his Millennium Bank backoffice to administer his payments.
