Abstract
In some embodiments, a smart card may include a substrate with a first side and a second side. A first protective layer covers the first side and a second protective layer covers the second side of the substrate. Circuitry held in the substrate includes electronic interconnects for interconnecting circuitry elements. The circuitry elements include a processor, power circuitry for powering the circuitry elements, and an environmental detection sensor for respectively detecting a predetermined environmental parameter. The processor is configured to receive an output from the environmental detection sensor, to determine from the output that the environmental detection sensor detected an environmental alert trigger condition, and to generate an alert that is representative of the environmental alert trigger condition. The protective layers include pores in a region proximate to the environmental detection sensor for exposing the environmental detection sensor to an environment around the smart card.
