Classification: CPC H  G  Y | IPC G  H

Claim 13:
14. A batteryless device, comprising,
a logic processor;
a power storage cell;
a sensor;
a persistent memory;
a wireless logic; and
an antenna configured to harvest power in response to exposure to radio frequency (RF) energy, the harvested power being transferred to the power storage cell such that when the power storage cell has a threshold amount of power the logic processor is activated to start or resume execution of code associated with a task of sampling the sensor, processing sensor data from the sensor into an encrypted message, and transmitting the encrypted message,
wherein the batteryless device transmits one or more of said encrypted messages using said wireless logic to a local device proximate to a location of the batteryless device, the one or more encrypted messages providing information related a state of a package to which the batteryless device is attached, the local device is configured for sending data related to said one or more encrypted messages to a cloud server for processing metrics related to the location and said state of the package, the local device being one of a plurality of local devices that become proximate to the batteryless device when the package moves proximate to said plurality of local devices at different times, and said metrics enable tracking over time of the package and said state of the package.
