Hello, i just have a question about the eway payment gateway module as we are looking to sign up with them. How is this gatway configured? is it using the eway shared page solution or the merchant hosted (XML) solution. Also are credit card details stored in our database when using this solution? I know that when we use paypal everything is done on the paypal pages which reduces our security requirements and risk. I was hoping that this would also be the case with the eway service? any info you can provide would be great. regards tom
