Can I use Curve as a credit card?

Excuse me, I was wondering if you could clarify something for me. The paragraph mentions Curve, and I'm curious about its functionality. Specifically, is it possible to use Curve as a credit card? I'm looking for a solution that would allow me to manage multiple cards and potentially earn rewards, so I'm hoping Curve might fit the bill. Could you please elaborate on whether or not Curve functions in this manner, and if there are any limitations or restrictions I should be aware of? Thank you for your time.
