TAMPER EVIDENT RADIO FREQUENCY IDENTIFICATION SYSTEM AND PACKAGE

摘要

A tamper evident package and system where the package has a radio frequency identification tag (14) affixed to or imprinted onto the covering. An interrogator (16) emits an electromagnetic signal to the identification tag which responds with a predetermined signal if the covering of the package (26) is intact and has not been breached or the identification tag (14) may be powered and emit the predetermined signal intermittently or continuously by itself. An attempt to enter the package (26) disables the identification tag (14) and will cause the identification tag, thereafter interrogated, to fail to send a signal or will send a signal that is different from the predetermined signal. The interrogator (16) recognizes the lack of or the different signal as an indication that the integrity of the package has been breached.
