"In 1970 I found little difficulty staying 30 years ahead of the man in the street, and now I find it difficult to stay 18 months ahead of the man on the street."
- Vernor Vinge

| Calster | ||
| A handheld device that printed legal currency on the spot. |
In the future world of the novel, most of life's necessities are free. However, luxury goods or experiences still cost something. To pay, you use a small box that prints currency for you, right on the spot.
| The robot hung up, and I did not have time to ask where I was supposed to look for the calster. I had no idea what it looked like. Getting up from the desk, which, abandoned, immediately shrank and shriveled up, I saw a kind of stand growing out of the wall next to the door; on it lay a flat object wrapped in transparent plastic and resembling a small cigarette case. On one side it had a row of little windows, in them showed the number 1100 1000. At the bottom were two tiny buttons labeled "1" and "0." I looked at it, puzzled, until I realized that the sum of 5000 had been entered in the binary system. I pressed the one and a small plastic triangle with the number one stamped on it fell into my hand. This, then, was a kind of stamping machine or press for money, up to the amount indicated in the Windows - the number at the top decreased by a unit. |

This is a strange sort of an idea, although it makes the future seem more real when computerized credit cannot pay for everything.
