Huh... I imagined something more... impressive.
Don't let the appearance fool you, these small, disposable paymemt discs can store billions of Venn worth of any currency. However, each disc can only hold one currency at a time.
What's with the weird design on it?
Each disc features a unique design to prevent mix ups. The millions of designs are sourced from different regions of space. Some depict corporate logos, political emblems, or... "art".
