The invention provides a master MMC/SD apparatus for simultaneously supporting bulk storage and Ethernet communication, a slave MMC/SD apparatus for simultaneously supporting bulk storage and Ethernet communication, a system composed of these two apparatuses as well as a method of operating the system. The apparatuses, system and method which simultaneously support bulk storage and Ethernet communication and which are based on MMC/SD interface enable a master apparatus with MMC/SD interface to support network function while maintaining bulk storage function as well, thus greatly expanding applicable areas of such embedded terminal apparatus with the MMC/SD interface that has bulk storage function.

System and method for supporting both bulk storage and Ethernet communications

The present invention is directed to an Ethernet communication method and system which are based on the MMC/SD interface. In the invention, the communication system includes at least one master device and at least one slave device, the at least one master device and the at least one slave device are connected via MMC/SD interface and communicate with each other on the Ethernet. The Ethernet communication method and system disclosed herein enables the device with the MMC/SD interface to act as a node in the network, and thus greatly expanding the application domain of such devices.

Ethernet communication system and method based on MMC/SD interface

A multi-application smart card and a multi-application management system and method for the smart card are provided. The multi-application smart card comprises a management device for the application security domain, and the management device is use to manage and maintain the application security domains in the multi-application smart card, and the application security domains comprise a plurality of issuer application security domains which share the control right of the multi-application smart card. Optionally, the application security domains also comprise at least one cardholder application security domain which is subordinate to the issuer application security domain that creates the cardholder application security domain, and wherein the at least one cardholder application security domain is used to manage and maintain the applications created by the cardholder.

Multi-application smart card, and system and method for multi-application management of smart card

The invention provides a Smartcard file system and its method for selecting file. Said file system, including MF as well as a variety of DFs and Efs in the MF, wherein application root directory (ADF) is added in the MF; the tile attributes of said ADF, DF and EF of the tile system include the Application Identifier (AID); when visiting with HTTP protocol, the AID is understood as a long file name. External entities accessing said file system with the HTTP protocol, namely locating the application and file managed with CWS via URL; in URL, AID of directory or file identities its long file name, so that Smartcard file system also can support long file system and the way of selecting file of URL, which makes Smartcard to support the WEB services easier and more accepted by the user.

Smartcard file system and file selection method thereof

A payment system and method of IC card and a multi-application IC card as well as payment terminal are proposed in the present invention. The terminal and the IC card perform off-line data authentication using an asymmetric key algorithm during an off-line transaction, and if the transaction is not approved in manner of off-line, the terminal and the IC card performs an on-line transaction via a host. Therefore, the payment system and method of IC card and the multi-application IC card as well as payment terminal disclosed in the present invention can be used both in machinery without on-line transaction environment and in standard merchant machinery with on-line transaction environment.

Payment system and method of IC card and a multi-application IC card as well as a payment terminal

A card to card transfer method used in the financial system is provided in the present invention, and comprises an initializing step, a transferring step and a transaction confirming step, wherein the initializing step includes the steps of calculating and obtaining the public key certificate and checking the amount of the transaction and so on, and the transferring step includes the steps of performing the transaction and so on. The present invention can achieve the function of transferring the electronic cash between two cards and can prevent the risk of repeatedly transferring the money into the card for transfer-in by using the card for transfer-out and so on.

Transfer method of electronic cash
