Abstract
An RFID tag having a non-volatile memory and a piezoelectric sensor. The piezoelectric sensor produces an electrical charge that momentarily supplies electrical power to the RFID tag when subjected to a mechanical force and the electrical power is sufficient to record data in the non-volatile memory. The piezoelectric sensor is affixed to an article such that an attempt to tamper with the article produces sufficient mechanical force on the piezoelectric sensor to record data evidencing the tampering in the non-volatile memory.
