Claim Text:
1. A dual mode detection device comprising: a dual mode microchip including a logic circuit and a non-volatile memory, wherein the dual mode microchip has an electronic article surveillance (EAS) mode and a radio frequency identification (RFID) mode; an antenna operatively coupled to the microchip for operation of the RFID mode; a coil separate from the antenna operatively coupled to the microchip; and a capacitor, comprising a ferroelectric dielectric material is integrated into the microchip that resonates with the coil at a specific frequency wherein exceeding a breakdown voltage of the capacitor alters a state of a memory location in the non-volatile memory in which the capacitor and coil form a resonance circuit in which the capacitor and coil form a resonance circuit.
