Various embodiments of the present invention are directed to stereo display systems. A latch is held by the housing, and a lanyard actuates the latch. The data field in the sector has synchronization patterns S. Substrate support elements, in the form of standoffs pins or bosses, are provided for supporting the multi-chip carrier substrate during the encapsulation process. The reader is capable of issuing commands to the RFID device, acted on by the transceiver in order to set states of switches in order to achieve a desired state for the RFID device.
