Do it the Swedish way_ put chips under your skin.
Do it the German way: if people do not voluntarily allow new chips on ID cards (for digital ID verification)being acivated because they do not want it, do not use it, do not trust the propaganda on how safe it is, wait until - like last month in Germany - the government looses patience and then mandatorily switches these chips on on new ID cards, no matter that people said clearly now over the past years. That is democracy in action: ask the people, but take their reply only when the reply is what you want to hear, else ignore it.
Combined with this new law from May comes an even more extensive package for loosenign privacy and data proteciton rights, and inviting business big data to datamine customers and private people, plus: a loosening of restrictions for government offices to access the biometric datapool from ID card holders. In the past years, access was restricted, but nevertheless such info requests exploded form year to year, grew by several factors every years. So much for "exceptions" and "only when the individual is a suspect in flight". It now becomes routine.
Add to this the face recognition software of public surceillance cameras. We are entering the time when state authprities will know about the whereabouts of everybody 24/7. Total control.
And then the terrorists will have no chnace anymore!
Already at present, police finds it almost impossible to track and fight financial transactions via the Hawala system. The new technology will not do anything to fight this, or to prevent terrorism. But the state's control of the ordinary people will remain.
Many critics have pointed out that any democratic state necessarily will and must lead to dicatorship, for economic, sociological reasons and reasons that are inherent to the logic of state organisation and bureaucracy. It cannot be avoided. One more argument for me to oppose the idea of states.
