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."
