If you have been reading here for a while you will remember my rant on these RFID tags that companies are claiming will not violate your privacy. But a recent test that Walmart did still have some people skeptical. My take on it is that when the cost of the devices makes it worthwhile and as technology improves someone could simply drive by your house and know you buying habits.
Will it come to this doubtful but it does make you wonder that when Walmart can do inventory control thru these little chips what else will they be used for. [The Register]
