The present invention is a mobile method and system for automatically monitoring the location and use of tools using radio-frequency identification ("RFID") tags. An RFID tag is secured to each tool with a unique numerical identifier. The RFID tag transmits its unique numerical identifier associated with each of the RFID tags using a RF signal, wherein the RF signal is transmitted at different intervals for each of the RFID tags. A receiver on a mobile platform reads the RF signals and determines the unique numerical identifier being transmitted. An information processor interconnected with the receiver analyzes the unique numerical identifier from a predetermined index, and the information processor determines whether any tools were not found on the index and automatically alerts a user when a tool is missing.
