I read about another idea for a "smart sneaker", this one was prototyped at
MIT I believe, and I think I read about someone putting it into production
but I'm not sure. Additional info would be appreciated.
This sneaker contained information about you: your phone number, stats,
resume maybe, stuff like that. When you shake someone's hand, who is also
wearing this type of sneaker, a small voltage transmits all your info to
them, and theirs to you. Later you go home and look at all their info on
your computer.
I think this would be great. Socially, it would serve the same function as
having a web page: you can have a store of information about yourself and
your interests that people can look at which might be awkward to bring up
out of the blue.
