Biometrics, the future?

Whilst doing into ways to disable objects its becoming increasingly hard due to thieves being able to think up techniques to break into your designs. A lot of electrical goods now have biometrics built in, giving a better level of security to the object, only the owner may use. But is this safe enough?Biometrics within a few years maybe a thing of the past if crooks can find effective ways of copying finger prints etc. Surely it cant be that hard to copy?It seems safe at the moment but I get the feeling it wont be on the shelves for a long period. (Please comment if you think otherwise or know any new info regarding this.)
