With the vending machine trend bringing more options to consumers, the need for a variety of payment types becomes more important than ever, according to a report by PYMNTS. In a study done by PYMNTS and Diebold Nixdorf self-service retail, 45 percent of self-service companies in America pay with debit cards, 29 percent pay with credit cards and just 19 percent of the 2,170 respondents reported using cash. 

The U.S. is behind some parts of the world going more cashless, such as Vietnam and China. Consumers want convenient and quick purchase options, which has created the need for and boosted sales in different types of vending machines.
