Integrated Eas/Rfid Device and Disabling Devices Therefor
First Claim
1. A semiconductor for use with an electronic article surveillance (EAS) and radio frequency identification (RFID) marker, the semiconductor comprising:
- a current receiving portion which couples to an antenna and is configured to communicate with at least one other portion of the semiconductor such that a multiplicity of functions can be performed by the at least one other portion of the semiconductor upon receiving and retransmitting energy and signals from the antenna; and
at least one of a first switch operatively coupled to the current receiving portion such that the multiplicity of functions are disabled upon closure of the first switch and a second switch operatively coupled to the current receiving portion such that at least one of the multiplicity of functions is at least partially disabled upon closure of the second switch.

Abstract
An integrated electronic article surveillance (EAS) and radiofrequency identification (RFID) marker is provided which a semiconductor device which may he coupled to an antenna for receiving and retransmitting energy and signals to the antenna. A current receiving front end section of the semiconductor device communicates with at least one other section of the device so more than one function can be implemented upon receiving and retransmitting energy and signals. A first switch is operatively coupled to the front end section such that the functions are entirely but reversibly disabled upon closure of the first switch thereby effecting a reversible EAS function. A second switch is operatively coupled to the front end section such that at least one of the functions is at least partially disabled upon closure of the second switch. RFID functions of the marker am retained upon EAS deactivation.
