The Nature of Digital Currency Options

[Ayeohx]

Since my campaign takes place in Seattle the nuyen is our primary currency. Unfortunately I have very little information on how the currency works.

Here's what I know:

1. Nuyen has digital signatures. (pg 124 Sprawl Survival Guide)
2. "The only way to counterfeit nuyen is to copy an existing certified credstick." (Forgery rules, pg 95 Unwired)

Here's what I need to know:

1. What media can nuyen be stored on? Banks and credsticks only or anything which has memory.
2. If you can store nuyen on anything, say an optical chip or a commlink, why would you specifically need a certified credstick for forgeries?
3. If nuyen can be stored on any storage media then how is nuyen stored? One file per nuyen?
4. Is every single nuyen tracked and by whom?
5. If I steal "Nuyen A" from Bank #1 can I deposit it in Bank #2? Or is that nuyen somehow flagged as stolen?
6. Similar to the above, say I hold up a fellow and transfer his money to a certified credstick. If he reports that money as stolen, is the nuyen flagged as stolen?
7. If nuyen can be flagged as stolen what stops people (Mr J) from paying people and they saying that money was stolen? And professionalism isn't enough; half the time they try to kill you.
8. Can you move nuyen from a bank account to credsticks or can this only be done by the bank that issues the credstick? The reason that I ask this is banks use to charge (and possibly still do) charge fees for certified credsticks equal to 10% of what went on the credsticks.

I know I'm missing a few questions but this is a good starting place. Please leave references for your post if at all possible. The more facts the better.
