Information about payment systems

At the moment I'm working with the following payment systems:

PayPal - the world's largest international payment system.

Robokassa - one of the largest players in the payment system market in Russia, more than 20 years on the market.

Yandex.Money - is an affordable and secure way to pay for goods and services over the Internet. Deposits and payments for orders are made in real time on the payment system's website.
