Banks are one of the indispensable elements of the financial system. Banks are enterprises that collect free funds from large economic units and use them in economic units that need money. Although this structure initially means an intermediary service, banks focus on both the role of attracting and offering funds beyond the intermediary service. By creating new investment instruments, banks are turning people's banking activities into a more customer-oriented structure by attracting people's interest. Increased connectivity leads banks to create and offer additional services in the field of financial transactions not only locally but also between countries. On the other hand, banks also offer services such as brokerage services, guarantee services, payment and settlement services, and guarantees for foreign trade finance. Today, banks continue to provide a wide range of services under the influence of technology. However, today the wide range of banking operations allows banks to become more profitable in the products they offer.
