Passive, low-frequency (~125 KHz) radio-frequency identification (RFID) is suggested as the optimum solution to track military weapons and sensitive items. The criteria for selecting a suitable RFID tracking system include: low cost, safety, reliability, longevity, durability, accuracy, precision, security, read distance and read speed. Passive, low-frequency RFID fulfills all these criteria. Alternative RFID technologies-high-frequency, contact memory buttons (CMB), and ultra wideband (UWB)-suffer from several important issues, most notably the lack of security and safety, reliability, accuracy and precision (high-frequency RFID); very high cost, lack of security, and too great a read distance (UWB); high cost, lack of security, poor read distance and speed, and longevity (CMB). We offer passive, low-frequency RFID as the optimum solution to accurately, reliably and safely identify, track and maintain weapons and sensitive items in the military and other agencies.
