ABSTRACT:
A coupler board includes an antenna that generates an electromagnetic field for wireless communication of data with multiple memory devices. The memory devices have data associated with operation of the machine stored therein, and may be configured as customer replaceable unit monitors (CRUMs) or system operation keys (SOKs). The memory devices may be in the form of radio frequency identification (RFID) tags. The electromagnetic field may have a dual-lobe radiation pattern to communicate with memory devices on either side of the coupler board. In one embodiment, the machine is a printing apparatus.
