Extension to pay

Hello everyone. I am developing a beverage dispensing app.
I wanted to ask you if there is any extension that can be added to my app that allows the user to make a payment (with credit cards or by scanning QR) and enables it to be able to dose.
In case someone is from South America, the "Mercado Pago" method would be very useful to me. And if not, any method you recommend will work for me.
Thank you so much.
