If your country doesn't have an online payment system, it's probably a low priority concern for your government / banking regulator. If there are no laws / regulation prohibiting it, that's great for you as you will have more freedom to build a system with whatever feature you want. But there's always the risk that as soon as you build something and introduce it into the market, you and your product will suddenly be under the government or banking regulator's glare. So the first step (and this is true for anything to do with the finance industry) is to study the banking laws and regulations of your country. The second step is to determine what FinTech infrastructure they have in place for banking, and what you will have to build and add-on to it. E.g: National Payments Corporation of India (NPCI) was created by India to be the backbone of its digital payment systems over its existing banking system - https://en.wikipedia.org/wiki/National_Payments_Corporation_of_India https://en.wikipedia.org/wiki/National_Payments_Corporation_... ... If your country already has something like that in place, then check if they offer a way for private entities to use it build on it. For e.g. NPCI offers an API Platform called Nfinite that allows corporates and startups to tap into their network and build new platforms (see https://nfinite.in/about-us https://nfinite.in/about-us ).
