There was some discussion of a similar idea at/after Extro 3, involving
name tags. Use IRDA transceivers (standard infrared components) to exchange a
data block. Your web address, name, a small photo of your face as a mnemonic.
Your public encryption key. Some of us can't remember names all that well.
So, as you register at a conference, the helpful person behind the counter
optionally takes your digital photo and hands you an active name tag.
I was almost tempted to build it. I figure an IRDA transceiver,
serial EEPROM, lithium coin cell battery, PCB, $10 each for the first few
