As per my understanding, every country has a payment processing system (both within the country and globally). One of the biggest examples is the SWIFT payment system.
For example in India,
National Payment of India owns UPI-based payments which came into existence a few years back and inforced UPI-based transactions which at the moment is a great success in a country where cash based economy still exists as they are instant and do not require any transaction fee.
An example:
If you did not have a penny or you were short of cash UPI was a rescuer as you can add a decimal and pay to the merchant or friend without paying a single penny as a fee, as it is a free service provided by the government.
In the same manner in other countries, there is VISA, MasterCard, or something else but every transaction takes a few days and you need to pay the transaction fee for within and abroad transactions.
As my belief is on Bitcoin and I know it was meant to be a payment processor as incepted still I do not know why it is not listed on that list. Which made me also question other blockchains that are known for instant payment and less fee.
