Also, the article is not claiming the thief was captured because of the RFID. The article is simply highlighting how the RFIDs in the chips foiled the thief by making the chips worthless almost immediately, and then goes on to highlight how RFIDs within chips are enabling casino operators to track user behavior in new and novel ways. The focus of the story is not that RFID was used to catch the bad guy, rather the focus is on how RFID tech within these chips has changed casino operation, from user tracking, to "turning off" stolen chips on demand.

The $.05 cost per plant does not mean that the unit cost is $.05...that is just the cost to buy proper coverage for one plant, even if that means that there is one sensor for every 100 plants.
