The article mentions that even "homeless people promoting charity magazines" use cards, but I really wonder how the homeless population, or others who typically make money through cash such as buskers and street performers, fare in a cashless world. Having a credit card requires a bank account at the minimum, and generally being "plugged in" to the system, where disadvantaged people rarely are. Of course, Sweden's welfare state is far more developed than the US, but the overall global trend in this direction is troubling.
