How to replenish the balance of a store abroad?

Question

Payment systems

Welcome all!
It is necessary to arrange payment for the balance of the online store for foreign users, there are no restrictions on countries.
It is necessary to make the most convenient function of replenishing the balance on the site through the payment system. These are mainly users of Asia, the American continent, the European Union.
I know that there is WebMoney, but is it possible to make sure that the user is not transferred to another site when replenishing?
As far as I know, there are a lot of payments in WebMoney and mostly those that are used by the CIS countries. Foreign users will be able to replenish only from the card.
Are there any good services that you know of? Please advise, thanks!
