This bill requires the National Park Service to accept cash payments for entrance fees at all national park units that charge admission. Currently, many parks have shifted toward electronic payment methods like credit cards and digital passes, which can exclude visitors without bank accounts or those who prefer to pay with cash. The legislation mandates that parks must continue accepting physical currency alongside any other payment methods they offer. The bill affects all national park visitors and park management practices but does not authorize any new federal funding or establish specific implementation timelines. By ensuring cash acceptance remains available, the legislation aims to maintain equitable access to America's national parks for all visitors regardless of their banking status or payment preferences.
