In one of the better uses I've seen for RFIDs (Radio Frequency ID), the power tool maker Bosch is going to put them in its line of portable power tools. Power tools are stolen frequently from construction sites, and with the purchase of a portable monitoring device, contractors would be able to keep better track of their tools. This is a sensible use of RFIDs that is much better than the creepy plans of some retailers who want to embed them in clothing so they can track us wherever we go (e.g. how many times a month we stop in Target, Walmart, etc.).
