I would like to know if there is any payment module for e-commerce ready to use with Redsys (credit card payment) directly, without using Ogone or any other payment gateway.

The problem is that, as far as I know, you have to pay to Ogone for registration, per month, per transaction and, at the same time, to pay to the bank for the payment gateway, per month, and per transaction, so you are paying twice for the same service.

In other platforms there are several modules for this and I think maybe is one of the few handicaps of Odoo, but very important.
