Information on the IRIS payment method.


IRIS is an online payment method that allows your customers to complete Smart Checkout transactions by logging into their bank environment and approving a specific payment. This method operates for most Greek banks and reaches almost all Greek users who use web banking solutions.

By default, all merchants in Greece are activated to accept payments with IRIS. All customers can pay with IRIS if they have a valid e-bank account that supports IRIS.

Some of the main benefits of offering IRIS as a payment method are:

User Experience
