In supermarkets, shopping malls, and convenience stores, the checkout counter serves as the "nerve endings" of commercial operations, with cashiers being the most dedicated "neurons" along these pathways. While focusing on improving product flow efficiency and enhancing payment experiences, we often overlook a long-standing occupational environmental factor—static electricity. Particularly for female employees who constitute the majority of checkout staff, adopting checkout equipment with advanced anti-static design represents not merely a hardware upgrade but a critical component of occupational health protection.
