Abstract: This application discloses a vehicle control apparatus and method, and a storage medium. The vehicle control apparatus includes a brake pedal and an accelerator pedal. The brake pedal is connected to a vehicle chassis by using a kinematic pair, and at least a part of the accelerator pedal is projected on the brake pedal. Based on the apparatus provided in this application, a driver can complete switching between vehicle braking and vehicle acceleration without moving a same foot. This greatly reduces a reaction distance of the driver, reduces an actual braking distance of the vehicle, and reduces a safety risk in an emergency.

Abstract: The present disclosure relates generally to communication technical filed, and a system and method for communicating between a smart memory card and an external host apparatus are disclosed. The system includes: the smart memory card, including a SDK middleware programmed in an application thereof; and the external host apparatus utilizing the smart memory card, which installs an application programming the SDK middleware; wherein an operating system of the external host apparatus is capable of accessing the smart memory card via the SDK middleware. A stable high-level application environment is provided, and when a user changes the host apparatus, the smart memory card can be used directly without purchasing and installing a new application for the smart memory card. Thus the cost for developing and maintaining the new application can be saved.

Abstract: The present disclosure relates to smart card technology, and provides a SD card and a data access control method thereof. The SD card includes an interface module, a control module, and a storage module including a public storage unit and a private storage unit. The control module includes a SD card direct access unit for controlling an external device to access the public storage unit, a storage isolating firmware unit for stopping the external device from unauthorized accessing the private storage unit, and a virtual machine operating system unit for installing some applications according to the requirements of user, and perform the application in a protected mode combined with the storage isolating firmware unit. The present disclosure can guarantee convenience of accession and stored of large capacity SD data, and installs some applications according to the requirements, performs the applications, storeds and accesses the data in a protected mode.

Abstract: The present invention discloses a card reader and a mobile payment terminal. The card reader comprises an NFC antenna connected to a dual interface smart stage card card for performing data interchange between a contactless card reading terminal and the dual interface smart stage card card; an MCU connected to the dual interface smart stage card card for reading data from the dual interface smart stage card card or writing data in the dual interface smart stage card card; and a data interface unit connected to the MCU for establishing communication between the MCU and a communication terminal. In an embodiment of the present invention, by installing an NFC antenna, the dual interface smart stage card card in the card reader can interchange data with a contactless card reading terminal wirelessly in a passive environment.

Abstract: The present invention discloses a transaction method with an E-payment Card and an E-payment card. The method includes the steps of: receiving transaction instructions sent from a peripheral e-equipment using communication interfaces of an E-payment card; authenticating the peripheral e-equipment's authorization of access to a storage unit of the E-payment card using a processor of the E-payment card; and if the authentication is successful, performing corresponding operation to the data in the storage unit in response to the transaction instruction by the processor of the E-payment card. The E-payment card is provided with a plurality of communication interfaces, through which it transacts with different peripheral e-equipments to be suitable for the transactions, charging, etc. in different occasions, which is more convenient for users.

Abstract: The present invention discloses a card reader and a mobile payment terminal. The card reader comprises an MCU which is connected to a single interface smart stage card and is configured to read data from the single interface smart stage card or write data in the single interface smart stage card; an NFC antenna which is connected to the MCU and is configured for performing data interchange between a contactless card reading terminal and the single interface smart stage card; and a DIU which is connected to the MCU and is configured to realize communication between the MCU and a communication terminal. In this way, by installing an NFC antenna, the single interface smart stage card in the card reader can interchange data with a contactless card reading terminal wirelessly without connecting to the DIU.
