Abstract: A detachable, magnetic tagging mechanism, and a system and method for using it, for conveying information related to control over the sensing of parameters, such as the heating of cookware or other food containers, to a reader communicating with, e.g., heating controls of a heater. The tagging mechanism may be removably attached to the cookware or other food container, is heat-resistant, and its shape can be changed to accommodate the heating of different sizes and shapes of cookware or other items. The tagging mechanism, system and method of the invention may be employed with different types of heaters, such as but not limited to magnetic induction heaters, and may communicate with readers using RFID or other technology and other communication modes and media.
