A temperature indicator includes a housing having a temperature detection assembly, switch circuitry, and a radio-frequency identification (RFID) module coupled to the switch circuitry. Responsive to the temperature detection assembly being subjected to a temperature exceeding a threshold, the switch circuitry causes a change in a value output by the RFID module when activated.

A temperature indicator includes a housing having a temperature detection assembly including a malleable substance. Switch circuitry having at least a portion thereof is disposed within the malleable substance. The malleable substance maintains the portion in a biased position. A communication module is coupled to the switch circuitry. Responsive to the temperature detection assembly being subjected to a temperature exceeding a threshold, the portion overcomes the biasing by the malleable substance such that the portion moves from the biased position relative to a conductive element that causes a change in a value output by the communication module when activated based on the portion either contacting the conductive element or disengaging from the conductive element.
