The purpose of this study was to examine the preferences of Australians who gamble on electronic gaming machines (EGMs) regarding cashless gambling systems. The researchers conducted a discrete choice experiment (DCE) to quantify the relative importance of cashless gambling system features. A total of 363 Australian adults completed the experiment. Overall, participants preferred a cashless gambling system that is smartphone-based, is consistent across all venues, and has mandatory spending limits. Participants also preferred a system that allows them to set the spending limit themselves and is linked to a loyalty scheme, where they could earn points for spending money and using harm reduction features. But even when a cashless gambling system with the most preferred combination of attributes is available, almost half (43%) would still prefer to use cash.
