Explain how biometrics are collected i'm like just born.

So I was wondering...

Biometrics is secure because nobody can guess it. So how do they map it out and encrypt it?

Also, the fingerprint sensor is a piece of metal so how do they sense it?

For technology overview of fingerprint readers:

You can usually tell as capacitive readers are a thin strip you pull your finger across, optical ones are a small square or circle you place your finger on.

That link doesn't load for me - and I suspect it's not targeting five-year-olds!
What's the gist?

Lol, We are not literally 5. But the link does work for me though...
