In a cashless society, the cash has been converted into numbers, into signals, into electronic currents. In short: Information replaces cash.
Information is lightning-quick. It crosses cities, states, and national borders in the twinkle of an eye. It passes through many kinds of devices, flowing from phone to phone, and computer to computer, rather than being sealed away in those silent marble temples we used to call banks. Information never jangles uncomfortably in your pocket.
But wherever information gathers and flows, two predators follow closely behind it: censorship and surveillance. The case of digital money is no exception. Where money becomes a series of signals, it can be censored; where money becomes information, it will inform on you.
