A flexible public transportation card (100) with display function is disclosed. The flexible public transportation card (100) with display function comprises a first card body (110), a second card body (120) and a flexible electronic system (130). The flexible electronic system is disposed between the first card body and the second card body. The flexible electronic system comprises a flexible display, a display circuit, a communication interface, a power generator and a capacitor. The display circuit is electrically connected to the flexible display. The communication interface receives a wireless signal. The power generator is electrically connected to the display circuit and the communication interface, and generates electricity according to the wireless signal. The capacitor stores the electricity generated by the power generator for providing the display circuit with the stored electricity, such that the flexible display displays a frame. The capacitance of the capacitor ranges between 0.1 and 20 microfarads.
