How people pay is critically important to consumers and businesses alike. Many consumers are choosing to pay for goods and services from an increasing number of options. Tech‐savvy urbanites buy coffee by tapping their phone on a reader. Parents returning from a night out use peer‐to‐peer payment apps, such as Venmo, to pay the sitter. The recent explosion of financial innovations promises faster, more efficient, and cheaper transactions. These increasing digital payment options coincide with decreased number and volume of cash (...) transactions. However, vulnerable populations face more constrained payment choices and often rely exclusively on cash. Without experience, devices, or acceptable credit histories, vulnerable populations may have little access to digital transactions. The advantages of falling digital costs and other benefits thus accrue to the digitally connected. At the same time, those who must transact in coins and paper money are likely to find their relative costs increasing. This paper highlights payment trends and the potential impact on vulnerable populations in the United States as we move toward a cashless society. This paper should stimulate discussions of public policy initiatives to mitigate digital payment issues for vulnerable people. (shrink)
