ABSTRACT:
A checkout station comprises a deactivation system having an antenna for transmitting a signal to the security feature on a product passing over the checkout station to deactivate the security feature and a scale for weighing the product at the checkout station. A composite weigh plate is supported by the scale and includes a metal face plate configured to support the product thereon for weighing the product and a metal sub-frame configured to support the face plate. The face plate and the sub-frame each define a slit so that they do not form a closed electrically conductive loop. An electrically non-conductive bonding agent fixes the metal face plate to the metal sub-frame to maintain the structural integrity of the composite weigh plate in spite of the presence of the slits in the metal components.
