More Information
Summary:The invention discloses a visual card and an information display method. After information processing is completed, latest information is displayed. A visual card based on an I2C protocol comprises anNFC chip, a control module and a display screen. The NFC chip is used for communicating with a non-access card reading device so as to carry out reading and writing operations and returning a sign indicating the completion of writing to the control module after the writing is completed. The control module is electrically connected to the NFC chip and is used for sending an APDU command for reading information in the NFC chip to the NFC chip by using the I2C protocol after the sign is received, and receiving the latest information returned by the NFC chip. The display screen is electrically connected to the control module and is used for displaying the latest information read by the control module. 本发明公开了种可视卡及其信息显示方法，其可在信息处理完成后将最新信息显示。种基于IC协议的可视卡，其包括NFC芯片、控制模块以及显示屏；所述NFC芯片，用于与非接读卡设备进行通信以进行读写操作并在写入完成后向所述控制模块返回表示写入完
