The world of finance and credit card processing is one of the most ensconced and deep-rooted industries there is. It's one of those that can only be penetrated by a company with deep-pocketed backers, experienced executives, and ambitious entrepreneurs. You're literally going up against a global market of banks and institutions that control the transfer of money throughout the world. And they're going to do all that is in their power to keep the status quo. On top of that, anywhere there's transactions of money, you're going to have throngs of fraudster and hackers trying to game your system (refer to the history of Paypal for more on this). It's certainly a massive undertaking that also requires you to hire top-notch talent; hence, you also can't cut costs on things like expansive offices and recruiting perks.
