I attended the conference last year that Philips presented with their products, especially the e-passport. I have had a small hand in some of the development of this technology in this country.
The reality of the matter is that yes, the data can be copied, certainly not easily but nonetheless hackable by people with unlimited resources.
The primary motivation for these technologies is not to eliminate forgery, it's more the desire of governments wanting to know every move their subjects make, and to spy on their citizens in the name of "security" and "anti-terrorism"
For some reason we have, in power in the various governments, a bunch of people who desire to control every aspect of us. The Yanks whom I hate seem to be rubbing this off on SA govt and various others aswell.
