The invention can read and write a memory card and the smart card synchronously and respectively through the memory card interface and the smart card interface, store necessary information through the storing device and satisfy the requirements of mobile operators expecting to read the high-capacity SIM card.
Description
Technical field
The present invention relates to data read-write equipment, the especially a kind of high-capacity SIM card reader that can read and write the desired vast capacity SIM card of mobile operator.
Background technology
Along with computer technology rapid development, various memory technologies have obtained widespread use, as the storage card of MMC (Multi Media Card) interface, the i.e. large-capacity storage media of multimedia storage card, and USB interface etc.
In recent years, the high security smart card that satisfies the ISO7816 international standard also is widely used, this type of ISO7816 type smart card generally is used for fields such as identification and user-specific information record, for example, be used for SIM (the Subscriber Identity Model on the communication terminal, client identification module) card is used for social security card of individual social insurance management or the like.Along with the development of mobile communication technology, mobile communication carrier is increasing to the capacity requirement of card.At present, MMC SIM card (BigSIM card), USB IC SIM card etc. that million level capacities occurred.
Because MMC SIM card and USB IC SIM card can be stored lot of data, so just need develop the read-write equipment of the reading and writing data that can satisfy this high-capacity SIM card.
Summary of the invention
The high-capacity SIM card reader that the purpose of this invention is to provide a kind of BigSIM card that can read while write USB IC SIM card, MMC interface and traditional ISO7816 standard SIM card; And the SIM card that can read while write large-capacity memory card and moving communicating field, possess the high-capacity SIM card reader of memory function.
The objective of the invention is by realizing by the following technical solutions:
High-capacity SIM card reader comprises: plate body;
Be arranged at the communication interface that can be connected with outer computer on the plate body;
Be arranged at the circuit that has main control chip on the plate body;
Be arranged at the intelligent card interface on the plate body;
Intelligent card interface on the described plate body comprises that at least one can form the SIM card interface that is electrically connected and supports reading SIM card information with SIM card;
The circuit that has main control chip on the described plate body is electrically connected with communication interface, intelligent card interface and SIM card interface respectively.
As the preferred technical solution of the present invention, also be provided with the memory storage that comprises storage card on the described plate body, and being arranged at the memory card interface that can read storage card information on the plate body, described main control chip is electrically connected with communication interface, memory card interface, intelligent card interface and memory storage respectively.
As the preferred technical solution of the present invention, described SIM card interface comprises ISO7816 standard card interface arrangement, and compatible multiple vast capacity SIM card simultaneously, comprise ISO7816 signaling interface, the MMC signaling interface of ISO7816 signaling interface, BigSIM card, the ISO7816 signaling interface and the usb communication interface of USB IC SIM card.
As the preferred technical solution of the present invention, the SIM card seat of described SIM card interface is provided with USB interface and MMC interface signal pin, USB interface and MMC interface signal pin switch by main control chip, be defaulted as the usb signal interface, main control chip carries out the bus switching when needs operation MMC SIM card, thereby realizes that the MMC signal connects.
The invention has the beneficial effects as follows: with respect to prior art, high-capacity SIM card reader provided by the invention not only can read while write storage card and SIM card respectively by memory card interface and SIM interface, can also be by the information of memory device stores necessity, enlarge the memory function of read-write equipment, can satisfy the requirement that the vast capacity SIM card is read in the mobile operator expectation.
Description of drawings
