The tourism industry is one of the largest industries in the world, which shows steady growth every year. It provides employment for more than 292 million people, or 10.2% of the world’s employment structure. Travel has changed significantly in recent years. To simplify the calculations during the trips, tourists first used cash, then traveler’s checks, and, ultimately, payment cards. With the development of means of transport and the invention of airplanes, traveling from one end of the world to the other became very easy.
