The Elysian Fields

A Japanese team is experimenting with storing data on fingernails with one possible use being storage of identification information - in other words, a replacement of smart cards. While that may make it a bit easier to misplace, I'm not sure it would do much to reduce theft - might make it a bit more painful than handing over a card - and is probably just as likely to be able to be forged. Still and all, there's the whole set of issues surrounding unique identification and how it can be used against you.
