Answer 1

Conclude an agreement with any payment system / bank.
Get access to their API.
Often, API documentation includes examples. Often in several programming languages.
And you will not get access to the card data. Either a redirect to the payment system website or an iframe is used, where the card details are entered.
The scheme is as follows:
1) In the API, issue an invoice No. AAA for the amount of BBB.
2) You are redirected to the website of the payment system
3) You receive information that the AAA account payment has been made or canceled (sometimes this is a callback, sometimes you need to request the API yourself).
4) After a day or two, the money will be credited to your bank account.
