Question

Mobile development

Good day! I am making an application focused on the global market. So, you need to make several payment methods to replenish the balance. Only come to mind:
1) Paypal
2) Qiwi
3) Payment by card (here is also the question of whether it is possible to implement native payment like in Uber for example)
4) Purchase as a donation in iOS applications

Answer 1

If to the world market, then WebMoney, Yandex.Money
