I would like to know how does companies like uber, bolt, lyft etc. do link credit/debit cards to the app. what api are they using to do that. I see when you put in card number it detect which provider is it from. Please advice.
Typically, businesses or merchants, as the ones in your question, integrate with one of the many Payment Processors in their region with the help of an acquirer. Can you elaborate a little more on “detect which provider” part of the question?
