The field of biostatistics and biometrics can also be applied to areas such as environmental study, agriculture, and general biological research.

Biometric technology can be used to take biological features of people, such as their eyes or voices, and use them as security devices. For instance, instead of using a PIN (personal identification number) to take money out of an ATM, in the future you might simply have to say your name and you'll be allowed to withdraw cash.
