An anonymous reader writes with this story about how a cashless society might work and how far-off in the future it is. "...We're not there yet, but a cashless society is not as fanciful as it seems. Recent research suggests that many believe we will stop using notes and coins altogether in the not-too-distant future. New payments technologies are rapidly transforming our lives. Today in the U.S., 66 percent of all point-of-sale transactions are done with plastic, while in the U.K. it's just under half. But while a truly cashless society is some time away yet, there is raft of groundbreaking technologies that will make cash a mere supporting act in the near future."
