:It's not the tech blokes who mess up the entire thing, it's the politicians, as usual. Technically, a contact-only card would serve the exact same purpose, for example, and do away with half the problems. Likewise, technically, all the mechanisms that actually could hope to make this thing halfway "secure" are optional... surely not by wish of the tech guys. All in all: your (and my) government doesn't give a damn about your well-being and those rights they did not (yet) take away from you, and solely cares about how to better keep tabs on you. Telling you things would enable you to keep checks on their actions, and they don't avoid that like the plague for no reason. By their own mantra "who has nothing to hide has nothing to fear (from having no privacy)", governments prove through their very own paranoid fear of being checked, that they do have something to hide.
