"SF looks towards an imaginary future, while fantasy, by and large, looks towards an imaginary past."
- Frederik Pohl

Hypercard  
  A virtual business card; what one avatar might hand another to introduce themselves.  

Better use the Japanese custom, and use both hands to respectfully receive one of these.

The hypercard is an avatar of sorts. It is used in the Metaverse to represent a chunk of data. It might be text, audio, video, a still image, or any other information that can be represented digitally.

A hypercard might contain all the books in the Library of Congress, or every episode of Hawaii Five-O that was ever filmed, or the complete recordings of Jimi Hendrix, or the 1950 Census.

Or, more likely, a wide variety of nasty computer viruses. If Hiro reaches out and takes the card, the information will be transferred from [the other] guy's system into Hiro's computer.
