This chapter presents the diverse use cases for money. “Use case” is a term taken from the technology industry, where scenarios are played out of how a piece of equipment or software might actually work once unpredictable humans are added to the mix. This chapter presents the use cases of money objects. From giving gifts to staging religious rituals, making political statements and playing around, people enlist money objects in a host of activities that we might do well to consider when we think we are redesigning money with new technologies.
