This payment extension for Magento 2.3/2.4 is designed for making credit card payments through Attica Banks e-Commerce system (Greece).
This payment gateway uses the redirect method where the user is redirected to the processing site (Attica Bank) to make the actual payment.
After payment verification, Attica Banks e-Commerce system 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 Attica Bank backoffice to administer his payments.
This module supports instalments.
