With Virgin planning its first space tourists over the next few years and industry wanting to branch outside of the atmosphere, a little thought of problem has been solved by the industrialisation of space: money. Coins have sharp, metal edges that can cause great damage in zero-g and credit cards would be completely wiped by cosmic radiation.
Currency exchange company Travelex has come up with a new form of currency that is completely spaceproof. Made of a similar material to non-stick frying pans, the QUID is heatproof at a high temperatures, has no sharp edges or toxic materials that could cause problems for the astronauts using them. Maybe in the future we’ll all be walking round space malls spending our tubes of QUIDS.
