is it possible show payment method in cart module?

hi.
is there anyway that my user can select different payment method in the cart module. i can write some php code but please advice me for which php file need to modify?

Hi,

You would have to first modify the file "cart" of the view "product" via the menu Display>Views to add the HTML of the payment method selection. And then, you would need to have some controller added that could be called by your HTML to update the payment method in the cart.
It's possible, but it will require complex coding.
