Debit card payment systems are known to induce more frivolous purchases in adults, but their impact on children is unknown.
Design and Methods
Using a national survey of 2,314 public school students in the United States, food purchases in schools with debit-only systems to those in schools with both debit and cash options are compared.
Students in debit and cash schools purchase more fresh fruit and vegetables and fewer total calories.
Payment systems with cash options have a lower purchase incidence of less healthy foods and higher purchase incidence of more healthy foods.
