How to resolve payment method issue

We're in the process of developing an e-commerce platform where the users balance are actually Points to be transferred from a 3rd party system.

Currently, we're planning to treat these Points as Reward Points in NopCommerce system. However, it seems NopCommerce checkout page only allows Payment Method which is non Reward Points based.

So my question is should we create a Payment plugin which treat the user's Reward Points (in NopCommerce) as a type of currency?

what are the consequences of doing so? My concern range from Orders Report / Payment Reports able to capture the spent Reward Points amount in the respective report.

Please advise me how to proceed with my problem.

You can checkout with points.  However, nopCommerce does seem to require at least one active payment method - at least, it is checked in the .cshtml file - e.g.

\Views\Checkout\OpcPaymentMethods.cshtml

        ... Model.PaymentMethods.Count > 0)

You may want to try modifying the .cshtml file to see what happens.

(As for reports, I don't know)
