Some thoughts
Is it society that defines the citizen or the citizens that define the society?
Many RFID tags, and indeed other traceable devices, are put their for the convenience and benefit of the manufacturer (temperature on Yoghurt is to help with supply chain management in case there is litigation later from a customer claiming food poisoning (Not our product M.Lord.. or You stored it badly...) but can be of benefit in tracking down to individual purchasing tastes. Neither of these cause me concern but the data in the wrong hands can be of immense "value" from which I derive no tangible return - indeed it costs me 'cos RFID is not without cost!
Only the customer pays - in the end - but we have no input to the process as legislators and manufacturers will decide. If mandated we can't withdraw.
Every product is required to carry a CE mark(?) and may be this is were the RFID ID tags and the like should be located so that a user - like me - can just snip it off if we don't want to be part of the system.
The only change to the law would then be the requirement to locate RFID tags in a removable position. Game over?
