The economic system used in NanoTrasen station operations is based on three distinct forms of currency: credits, cash, and coins, each serving a different role within the economy.
Credits are the primary currency used throughout known space. Nearly all official transactions, payroll, and commercial activity are conducted using credits. Because every transaction is electronically recorded, they provide a transparent and easily auditable financial trail.
Examples:
Employee salaries
Taxes
Fines
Cargo and supply orders
Cash is a physical medium of exchange that has largely fallen out of use. It remains common among technologically underdeveloped civilizations, although more societies continue to transition toward credit-based payment systems.
Within modern spacefaring society, cash is most often associated with transactions intended to avoid official oversight or with activities of questionable legality.
Examples:
Bribes
Off-the-record payments
Pre-spaceflight economies
Contraband trade
Coins are a tertiary form of currency with virtually no practical economic role. Their face value is negligible, and minting them has long been considered economically unjustifiable. As a result, genuine coins are exceptionally rare and are generally regarded as collectors' items rather than usable currency.
However, some older vending machines still retain functional coin slots. Rumor has it that inserting a coin into one of these machines may dispense an item of unusually high quality.
Examples:
Purchasing rare or mysterious items from vending machines
Selling to collectors
Exchanging for credits at twice their face value
Other forms of currency continue to exist throughout known space. These typically include local currencies used within star systems that have yet to fully adopt the credit standard, barter systems maintained by isolated or technologically primitive settlements, and culturally significant mediums of exchange.
Some currencies derive their value not from economic utility, but from tradition, symbolism, or rarity. For example, bananium and coins minted from it are considered highly valuable among Honk minorities, where they hold both cultural and economic significance.
