Target is slowly joining Walmart on RFIDs. This is great. Keep going. Unfortunately, misguided privacy activists want stores to destroy the tags as you leave the store. RFIDs could be a very powerful way for people to track the goods that they buy. For example: it would be great for insurance purposes (have you ever tried to catelogue your household items before a move?). In this case, the benefits far outweigh any negative privacy issues.
