Claim:
1. A radio frequency identification (RFID) tag comprising: an accelerometer, configured to communicate an acceleration reading of the RFID tag; and a microcontroller unit (MCU), configured to transition the RFID tag through one or more states, and operably connected to the accelerometer, wherein the MCU is further configured to: awaken, based on a trigger, where the trigger causes the RFID to transition from a sleep state to a motion detection state; if the RFID tag is in the motion detection state then: provide temporary power to the accelerometer via the MCU only; receive, from the accelerometer, the acceleration reading of the RFID tag; calculate, based on the acceleration reading of the RFID tag, whether the RFID tag is in motion or not; and if the RFID tag is in motion then: transition to an in motion state by ceasing the temporary power provided to the accelerometer and configuring the accelerometer to receive power directly from a battery power source only; if the RFID tag is not in motion then: powering down the MCU until a next trigger and ceasing the temporary power provided to the accelerometer.
