One device as bankcard and OTP generator

On a previous response, I marvelled at the ability to get a OTP display onto/into a credit card, together with battery and keypad! Amazing.  I proposed that RSA (for example) could get the technology onto handsets much easier and do away with the separate token altogether.
Well apparently this is already done (for BB, J2ME, Symbian etc) so I might also look for this option to allow the ditching of my token from my man-wallet.  RSA OnDemand is also an option - its just a server side generated OTP. 

And I found the following video links which show the EMUE unit:

Oh, yes, and according to the EMUE video, the cards are made by NagraID in Switzerland:

I love the idea of getting rid of my token, I love the idea of real transaction authentication, but I'm still worried about Man in the Middle.

A MiM would still be able to use the authentications from this device to transfer moneys into alternative accounts.  So does this actually answer the question, or is it just a very pretty version of the CAP reader?

Looks great, but it'll be expensive & does it really finish the job?
