Could you please elaborate on what exactly PXP payment is? From the brief description, it seems that PXP Financial is a comprehensive payment provider offering businesses the capability to receive payments both online and in-person across the globe. However, I'm curious about the specifics of the PXP payment method itself. Is it a type of cryptocurrency, a digital wallet service, or a traditional payment gateway that supports multiple currencies and payment options? How does it compare to other payment methods in terms of transaction fees, security, and ease of use? I would appreciate a more detailed explanation to better understand the nature and benefits of PXP payment.
