My company handed out framed certificates for a single share of stock as a commemorative gesture. It's pretty, but what I really want is to know how much it's worth.
I think a small embedded chip, display, and bluetooth could easiliy get you an area below the certificate that says "This share of ACME stock is worth $5.32.".
Even better would be a graph of the share's value over time.-- drzeus, Nov 03 2005 Interesting. Once everything has RFIDs in it, one can imagine displaying a real-time value for everything in your house at any given time.-- theircompetitor, Nov 03 2005 I like this. I often give a single share / certificate as a gift to newborns. This doesnt amuse them until they are much older, but the display might.-- Shz, Nov 03 2005 random, halfbakery
