ABSTRACT:
The present invention is a method system that detects the altering of the contents of a package. This system comprises a Radio Frequency Identification (RFID) tag that is affixed to a package. This RFID can receive, store and transmit information received related to the package contents. A pressure sensitive material is positioned in the package such that this material can sense the weight of the package contents. When the weight of the package contents changes, the RFID tag will receive a signal directly or indirectly from the pressure sensitive material. This weight change is recorded in the RFID. When a RFID reader energizes the RFID, this current package weight is transmitted to the RFID tag reader. The RFID tag reader can then determine if the weight transmitted by the RFID tag is the original package weight or a new package weight. A new package weight would indicate some altering of the original package contents.
