Capture payment information for cart

We have a php shopping cart program (CartWeaver3) that requires integration of payment details into the order form at checkout. At the moment CartWeaver only only offers ready-built third party payment gateways (PayPal etc), whereas we want to continue to capture card payment details for processing manually later (via a terminal). The successful bidder will amend the existing CartWeaver files to include this option, so we can capture and process this data separately. ## Deliverables The successful bidder will integrate their additions and amendments into the existing CartWeaver installation, so that customers can input their payment details at checkout, and we can access the data from within the admin interface. We have an existing site which uses the asp version and we'd like it to operate in a similar or intuitive manner. Full access and login details will be given.
