Australian "calculatorcard"

["Cees de Groot" <cg@bofh.toad.com (none)>]

Hi everybody,

Yesterday, on UK Discovery, there was an item in the programme Beyond 2000
about an Australian card which implements a challenge-response protocol
and can be used for banking, etcetera. Basically, you give your card
number (over the phone), get a challenge number, enter your pin and
the challenge, and then give the response. All in CC format...

They plugged it as the ultimate identity-prover, so I'm kind of interested
in what's behind. Now, I know that Discovery constantly repeats old
stuff, so I'm not sure whether this is actually hot/new/... 

Can anybody provide me with pointers to more in-depth information about
this device and the algorithm(s) behind it ?

Thanks
