An active card, such as a smart credit or debit card, includes a substrate, a piezoelectric film sensor embedded in the substrate, and an active card module embedded in the substrate and coupled to the piezoelectric film sensor. The piezoelectric film sensor receives an input stimulation and outputs a voltage in response to the input stimulation. The active card module receives the voltage generated by the piezoelectric film sensor and executes a function. |
