On Ship Currency

Credits
Currency on board revolves around Credit Chips (More commonly referred to as Creds). Everyone aboard has one of these cards, which is topped up with a weakly allowance based on their position. It is important to note that the allowance depends on the skill required for the work, and the associated danger. As such Fighter Pilots are some of the best paid on the Arks. This currency is used within the Hub to buy goods such as clothing, exotic foods and drinks or paying to see something in one of the theaters or cinemas or to even go bowling. Credits are not used when gambling, instead a 'goods against goods' system is used.

Items necessary to someones survival such as basic food, water and healthcare are all free. Basic foods are the likes at which you would see in a schools cafeteria or a small café.
