If I understood you correctly, you are looking for a way to have your jotform accept payments over some other payment processors and have that same data sent to our servers and stored there?
If so, that would only be possible by utilizing a full source code of your jotform and making the necessary changes for the payment. Of course, in such case, you would need to program the code to capture the response from some payment processor and send that data to your jotform - to be saved.
This, as already mentioned, requires you to add a lot of functionality to the form by yourself / your developer(s).
However, please do take note that if you'll ask payment from your users, you need to use our Payment tools. If not, you can still pass information to your POS but not using plain form fields that ask for sensitive information like log in credentials, credit card details, bank information, etc... Please see our "Terms" page under the "Phishing" section.
Also if you don't want to use Paypal you can use some other payment integration.
Hope this will help. Let us know if you need further assistance.
