: Developing payment gateway I have an idea of developing internet payment gateway similar to PayPal or Webmoney. Since i'm only sophomore at Computer Science, and i've only taken intermediate programming

There are no books that cover this. This is a topic that goes way beyond what you can write in a book. The technical, security, and legal issues are huge. If you need a book to learn how to do this then you you shouldn't be attempting this. This is something a large team would be doing.

You'll need to use a high level language like C or C++ because speed is hugely important in financial transactions.

If you're going to have US customers use this service you're going to want to have servers located in the US for speed purposes which mean you will have PCI compliance issues to deal with. This isn't easy t do and would be expensive both up front and on an ongoing basis.

Fraud control. What do you know about it and what can you do about it That alone is a huge task that would require a team with lots of experience to tackle it. The largest and fastest growing part of any payment provider is the fraud department. Unless you can get a handle on that from day one you're not going anywhere.

Also, if you're just learning how to program then this is definitely way above your skill level. Even if you can work out the legal and security issues the programming is still above your head. Sorry to sound pessimistic but this isn't like building an ordinary website. This is a monumental task. I have a friend who is currently working on a huge financial project similar to this and just getting the necessary financial institutions on board has been a year long project.
