What is a network payment?
Could you please explain what a network payment is, in simple terms? I understand it's related to finance and transactions, but I'm not entirely clear on how it works. Is it a type of online payment system that allows users to send and receive funds electronically? How does it differ from traditional payment methods, and what are the benefits of using a network payment system?
