Security in blackberry: Smart card reader.

RIM sent to the BlackBerry Smart Card Reader a "solution of security" for blackberry that is, in fact, a card reader with connectivity bluetooth.
What it does? Simple... put the card in the equipment with blackberry and if you go away of her you can totally blocked and not to unblock it unless you are system administrator directly. The interesting thing is that, at corporative level, the one that defines the meters of "distance" and blockade is not necessarily the user of the equipment but that admin of security and has encripción AES and validation with standards of the DoD of the USA.
