Sensors and method for verification of agents - powder, liquid, gaseous or other agents - in a vessel

A method for validation of agents in a vessel comprising:

• embedding physical characteristics and definitive information related to the vessel, at a time of manufacture, into a lockable electronic memory portion of an embedded device;
• embedding updateable information into an updateable electronic memory portion of the embedded device;
• and
• interrogating a filled vessel upon deployment by software on a portable device via a communication link to verify the physical characteristics and information, wherein a match of information constitutes a validation, wherein the embedded device is normally passive and is activated upon interrogation;
• and
• the embedded device includes a sensor attached to a threaded plug housing, the threaded plug housing removable disposed in the vessel.

A sensor set comprising:

• a lockable electronic memory portion having embedded physical characteristics and definitive information related to a vessel, at a time of manufacture;
• a sensor for detecting contents of the vessel;
• and
• a communication link for communicating with a portable device having software for receiving data from the sensor, the software being able to verify the physical characteristics and information from the sensor.
