Is DPS Pro compatible with One Step Checkout modules?
There are a large number of different One Step Checkout modules, and unfortunately the majority of modules do not load the original Magento instructions for the checkout process, which includes a checkbox for the customer to save their credit card details for future use.
If you are using a One Step Checkout module, please get in touch with us to check whether the module you are using is compatible with Fooman DPS Pro and the secure tokenised billing feature. We are currently working with module developers to try to resolve this issue and will update our website once a solution has been found.
