This IRIS PrestaShop payment gateway is designed for making online payments through online banking (Greece).
This payment gateway uses the redirect method where the user is redirected to the processing site (IRIS) to make the actual payment.
After payment verification, IRIS 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 backoffice to administer his payments.
You will receive the module by e-mail after your payment.
