Yes, that's precisely the point - if the card is stolen, the service is stolen with it. I'm not trying to prevent that, I'm trying to _tie_ the service to the card - whoever has the card runs the service. If you see that the card is gone, you know your service is gone too. If the card is still there, your service keys are safe.
