I am new to mobile development, I would like to ask about those who have been doing this for a long time. Can you integrate the paypass payment method into the android app or the like? How do they integrate? Is this part of the functionality provided by the operating system or part of the Master Card company's API (if so how to integrate it, for this, as I understand it, a contract with a master card is required)?
I want to do something like a cough.
