Space Money Invented For Space Tourists
An anonymous reader writes "The foreign exchange company Travelex has invented a unit of currency designed to be used in space commerce, the Quasi Universal Intergalactic Denomination (QUID). The QUID is made of a space-qualified plastic, with round edges to prevent injuries in zero gravity. One QUID is equivalent to about 6.25 pounds, 12.50 dollars or 8.68 Euros. Of course, space currencies are already a staple of science fiction, with 'credits' being the most popular."
They took the time to design a new monetary format and didn't even make it based on a Balanced Ternary system. Balanced ternary cash would be quite nice, it would mean almost always having the exact change, you only need one coin of each denomination to ensure you can make change for any possible transaction among other nice qualities.
