Own currency on the site?

Question

Payment systems

You need to integrate your currency on the site. I don't know how to implement all this.
Deposit+withdrawal of funds MasterCard + Visa + PayPal + WebMoney for maximum coverage of the audience.
Examples of currencies at the links:

The user bought a replenishment package on the site, N points 1$ = 1000 points were credited to his account (for example).
I wanted to withdraw, displays on the selected service, site and service% of the withdrawn amount 10,000 points = 10 $ -% (commission).
Where to dig? What APIs should I use? Where can I read more details? Action algorithm? How to do it all?

Answer 1

Replenishment is easily done through Yandex.Checkout - if legal. person or through Ya.Dengi, WebMoney Merch if physical. face. I would not make the conclusion automatic, because. there is a possibility of "coolhackers". Also, in order to avoid confusion, I recommend 1 ruble = 1 point to make it easier to count.
