I was asking a local bank about the possibility of transferring money to my account there upon publishing a paid app on play store. The reply was that they have their own payment gateway that deducts a percentage of the profits besides monthly and yearly charges.
My first question is what exactly is a payment gateway? (The information written on google about this is very confusing and very broad that after hours of research I still do not know what exactly is the benefit of a gateway.)
My second question is do all banks around the world impose this "gateway"deduction?
I always thought that money is transferred directly from google to the concerned developer's bank account without the concept of gateway. Please correct me if am wrong.
Thank you!
