Credit

Credits are a form of universal currency apparently used worldwide in Deus Ex, Deus Ex: Invisible War, and Deus Ex: Human Revolution. Credits are the official currency used in Germany, France, The United States, Egypt, Canada and the Peoples Republic of China. They are mostly used digitally through the Internet and ATMs, but despite what their name implies, physical financial transactions can also be made through the use of Tangible Credit Chits - Green vouchers that may hold anywhere from 50 to several hundred credits. It is unknown where credits originated, but they were likely created by Majestic 12 or the Illuminati, as it supports their goals of centralization and control. Credit chits return in Deus Ex: Invisible War, though they are now thinner, gray, and shaped slightly different. The Symbol for credits is ¢ in the first two games, and V in Human Revolution.

Value
In 2052, it costs 2 credits to purchase a Soda or Candy bar from a vending machine, and 8 to purchase a pack of 'Coughing Nails' Brand Cigarettes. Most Bartenders worldwide will sell cheaper drinks such as Forties and Liquor for 10 credits. Non-explosive and non-energy Ammunition usually costs several hundred dollars, and explosives such as LAMs and Rockets have a street value of multiple thousand credits. Few people keep more than a thousand credits in their ATM accounts.

Trivia

 * Despite occurring after a 20 year economic depression, Credits in Invisible War are worth more than they were in Deus Ex.
 * In Deus Ex, a Gas station is visited that has been abandoned since the Californian Earthquake Disasters in 2030. The station states "Same price Cash/Credit," implying that dollars were still the national US Currency in 2030. As Credits are used in Deus Ex: Human Revolution, which occurs in 2027, this could mean dollars, but most likely it refers to the difference between tangible and digital credits.
