The Quasi Universal Intergalactic Denomination, called the 'Quid', is a recently created currency for use by space tourists. The idea was to have a form of currency that would have no sharp edges, no harmful chemicals, and be made out of a material that would stand up to the rigors of space travel. The Quid is made from teflon, and has rounded edges to prevent damage in low gravity environments. The full name is a backronym from 'quid', a slang term for the British Pound.
