1. An induction heating system comprising:
- a container to store a substance;
a heating element in thermal contact with the substance;
a machine readable tag in thermal contact with the substance, the tag storing a tag identifier and having a machine readable temperature-dependent characteristic;
an interrogator to read the tag identifier, to read the temperature-dependent characteristic of the tag, and to determine a current temperature of the substance from the temperature-dependent characteristic;
an induction heater to generate an AC magnetic field to heat the heating element; and
a heater controller to control operation of the induction heater, in response to the substance temperature determined by the interrogator, to heat the substance.
