Finally, really plastic money. Once completely disembodied, digitized money escapes from a single transmission form and merrily migrates to whatever medium is handiest. Separate billing fades away. Accounts can be interleaved with the object or service itself. The bill for a video comes incorporated into the video.
Invoices reside alongside of bar codes and can be paid with the zap of a laser.
Anything that can hold an electronic charge can hold a fiscal charge. Foreign currencies become a matter of changing a symbol. Money is as malleable as digitized information. This makes it all the easier to monetize exchanges and interactions that were never part of an economy before. It opens the floodgates of commerce onto the Net.
