Fingernail Storage

Japanese researchers are using femtosecond laser pulses to write data into human fingernails. Capacities are said to be up to 5 mega bits and the stored data lasts for 6 months – the time it takes a fingernail to be completely replaced.”I don’t like carrying around a large number of cards, money and papers,” Yoshio Hayasaki from Tokushima University. “I think that a key application will be personal authentication. Data stored in a fingernail can be used with biometrics, such as fingerprint authentication and intravenous authentication of the finger.”Sounds better than fingerprint recognition. At least the crims only have to tear out your nails rather than lop your finger off when they want to jack your car.
