In the world of payment systems, just as credit cards are an indispensable product, a payment scheme is indispensable for credit cards too.
When a credit card product is launched, it is first decided which scheme it will be issued under. A BIN number is obtained by contacting the relevant payment scheme company. After the necessary certifications, the cards are made available to customers.
The card scheme is the logo located in the lower right corner of a credit card.

What are the payment schemes?
There are two types of payment schemes: national and international.
