Touchless technology refers to systems that allow users to interact with devices without physical contact. This technology often uses sensors, cameras, or voice recognition to detect gestures or spoken commands. Common applications include smartphones, home automation systems, and payment systems, enhancing convenience and hygiene. The rise of touchless technology has been accelerated by the need for safer interactions, especially in public spaces. By minimizing physical contact, it helps reduce the spread of germs and viruses. Examples include touchless faucets, automatic doors, and voice-activated assistants, which streamline daily tasks while promoting health and safety.
