Implementation of a payment method registration and utilization system

Hi, everyone. Here's the first question.

We would like to implement a system that allows you to subscribe to the service by registering payment methods such as cards or bank accounts in the service and selecting them. For example, in the case of watchaplay, you can register and pay with a card if you have a card number, an expiration date, and a seat in front of the resident number. If you think about Apple, there's a system that registers a card in an Apple account and subscribes to Apple Music or iCloud. I'm trying to build a system like this, but I don't know where to start. Currently, not all of my development team has implemented the payment system. Even if I tried to search, I couldn't get the result I wanted because I didn't know the right keyword.

To summarize the questions, it is as follows.

I would appreciate it if you could let me know if there is a site where I can ask for advice on these questions or if you have any data.

If implementing such a system is tricky, I'm fully willing to use PayPal or other simple payment systems.

Thank you.
