is there an opportunity to pay for the product with part of part . the buyer has the money to a one card that is not enough to pay for, but he has another card and wants to pay together. I want to create system for this. Is there any ideas?
You don't want this, except you have a lot of time for reading and learning or you are an expert or want to get one for shared transactions.
- Magento doesn't do this out of the box.
Why this is so hard to implement I explained here: https://magento.stackexchange.com/a/11613/217
