What is PSP app for payment?
Can you explain to me what exactly is a PSP app for payment? I've heard of it in the context of cryptocurrency and financial transactions, but I'm not entirely clear on its functionality and purpose. Is it a specific type of software that facilitates payments? If so, how does it differ from other payment processing platforms? Additionally, are there any security measures in place to ensure the safety and security of transactions processed through a PSP app? I'd appreciate it if you could provide me with a concise yet informative explanation of this topic.
