Devices, systems, processes, and articles of manufacture are provided herein. These may include an RFID transponder having a microprocessor, nonvolatile memory, a battery, and an antenna, wherein the microprocessor is configured to operate in a passive mode and a battery operated mode, and wherein, when in the passive mode only a portion of the microprocessor may be powered by energy received from an RFID reader interrogating the RFID transponder. The RFID transponder may further include MEMS sensors coupled to the microprocessor and the microprocessor may be further configured to add physical data, instructions, or a unique identifier of the RFID transponder to the nonvolatile memory.
