Which payment system to choose to accept payments worldwide?

Question

Payment systems

Need a payment system for the application to accept payments in different currencies from different countries.
For example, we have a bank account in Russia. A user from Germany wants to pay for something in our app. It is necessary that the system understands that a person will pay in euros (or whatever it is) and show the converted cost in euros from the original price in rubles.
Visa/Mastercard is enough to accept payments. Mandatory work with legal entities of the Russian Federation and Ukraine.
There was an idea to use the Single Checkout, but apparently their SDK does not allow displaying the cost in the currency in which the person will pay, and not in which our account.
Are there any disadvantages of using native apple and google payments? Since we have applications only.

Answer 1

Universal Swiss knife - can do a lot, but individual tools do their job better and better.
It is the same with payment systems: one universal one is a vicious path.
Therefore, it is quite rational to use different payment systems for different countries, currencies and types of payments. Up to the size of the payment, tk. some payment system can take a small percentage of the commission, but not less than a fixed amount, and the other, and then it will be unprofitable for small amounts. Well, etc.
