Asia has a very unique financial system in this sense. They are not reliant on 3rd party payment processors that can be counted on one hand, and they usually support P2P payment between banks. They also usually prefer to use QR than NFC (like on wechat, line, and kakao). This is one example standard that I found from Indonesia called QRIS, and they are expanding it wherever they can. Of course Visa is upset about those lol (see the section about US Government response)
