Abstract
The utility model discloses a card reader which is used for conversion between an IC interface and a USB interface. The card reader comprises a safety master control chip, a USB interface circuit and an IC card interface circuit. The safety master control chip is respectively in electric connection with the USB interface circuit and the IC card interface circuit. The USB interface circuit is used for being connected with a client computer. The IC card interface circuit belongs to a card reader circuit and is connected with an IC card. The card reader is convenient to carry, keep and use. From the aspect of costs, each user can have IC KEY identity authentication issued by different banks as long as the user has simply one card reader. Meanwhile, the user only needs to install driver software of an IC KEY-to-USBKEY card reader on the relevant client computer. Therefore, the card reader is simpler and more convenient compared with the prior art that driver software needs to be installed for each USBKEY or USBKey.
Description
Technical field
The utility model relates to a kind of card reader.
Background technology
Generally adopt in the market different banks or financial institution distribution USB KEY or U shield separately, and the USB KEY of each bank or mechanism or U shield, difference is very large, and corresponding software-driven is also arranged separately.
There is following shortcoming in above-mentioned technology:
(1) consumer carries inconvenience, and such as being with possibly several USB KEY or U shield, also inconvenient itself and general bank card are put together taken care of in addition, such as being placed in the wallet.
(2) each USB KEY or U shield will be installed separately corresponding driver, and be relatively loaded down with trivial details.
(3) cost of USB KEY or U shield is higher.
The utility model content
The utility model proposes a kind of card reader, the user can finish conversion from the IC interface to USB interface by this card reader.
The utility model solves described problem can be passed through to realize by the following technical solutions:
A kind of card reader, in order to realize the conversion of IC interface and USB interface, it is characterized in that, comprise a safe main control chip, one usb circuit, one IC-card interface circuit, described safe main control chip is electrically connected respectively with described usb circuit and described IC-card interface circuit, described usb circuit is in order to connect with client computer, described IC-card interface circuit is card reader circuit, be connected with IC-card, this IC-card interface circuit can be Contact Type Ic Card interface circuit or non-contact IC card interface circuit, or comprises contact and non-contact IC card interface circuit.
Especially, this card reader also is provided with a storage unit that is electrically connected with above-mentioned safe main control chip.
Especially, described card reader by USB interface from the client computer power taking.
Compared with prior art, the utlity model has following advantage:
1. the user only need hold the card reader that an IC KEY turns USB KEY, can realize the IC KEY of some banks or financial institution distribution, and IC KEY conveniently takes care of owing to similar with bank card.
2. cost is lower, buys 2 IC KEY and 1 IC KEY turns USB KEY card reader such as the user, and 2 USB KEY or U shield are cheap than buying.
3. each USB KEY or U shield will be installed drive software separately, and adopt IC KEY to turn USB KEY card reader, then as long as a drive software is installed.
Description of drawings
Figure 1A ~ Fig. 1 C is the first embodiment logical organization block diagram of the utility model card reader;
Fig. 2 is that the second embodiment of the utility model card reader uses synoptic diagram.
Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, below in conjunction with embodiment and cooperate that accompanying drawing is detailed to give explanation.
The bank card medium is in the stage from magnetic stripe card to the IC-card transition at present.Magnetic stripe card does not possess security feature.And IC-card itself possesses security feature from principle, can support the functions such as safety identification authentication and digital signature, so that bank IC card possesses the function of U shield fully, can be used in the network on-line payment.
The utility model purpose provides a kind of card reader, can read the information of IC-card.
Please refer to Figure 1A, Figure 1B, Fig. 1 C, described card reader is in order to realize the conversion of IC interface and USB interface, comprise a safe main control chip, one usb circuit, one IC-card interface circuit, described safe main control chip is electrically connected respectively with described usb circuit and described IC-card interface circuit, and described usb circuit is in order to connect with client computer, described IC-card interface circuit is card reader circuit, is used for the IC-card read-write.
In certain embodiments, the IC-card interface circuit is the Contact Type Ic Card card reader circuit, is applicable to Contact Type Ic Card;
In certain embodiments, the IC-card interface circuit is the Contactless IC Card Reader circuit, is applicable to non-contact IC card.
During described client access IC-card, send instruction and data for safe main control chip by usb circuit, safe main control chip is handed over mutually by IC-card interface circuit and bank IC card, and the result is returned to client computer by usb circuit.
Described bank IC card is a kind of smart card, and there is the hardware security chip inside, storer, and in order to realize safety certification and cryptographic algorithm, namely this IC-card possesses logical encrypt calculation function and storage digital certificate functionality, possesses the same function of USB KEY.
Please refer to Fig. 2, be the use synoptic diagram of an embodiment of card reader of the present utility model.Using card reader to read in the IC of the bank information process, also relate to bank server, client computer.This card reader for card reader provides power supply, after client computer need to be installed and is driven into accordingly during use, can be carried out data communication from the USB interface power taking of client computer.During use, card reader inserted the client computer USB interface after, can carry out reading and writing data after the IC-card sheet being inserted the IC-card seat of card reader.The below introduces the using method of this card reader to finish bank paying as example:
(1) drive software of bank's card reader is installed in client computer;
(2) user inserts bank IC card in the deck of card reader, and this card reader is connected with client computer by usb circuit;
(3) user is by the application software of client computer, connects bank server, the logging in to online banks system, and read IC-card information, identifying user identity by card reader;
(4) user carries out transaction payment, and sends transaction request to bank server;
(5) after bank server is subject to transaction request, verify processing, conclude the business, and corresponding information is sent to the application software of client computer.
The utility model is from easy to carry, convenient keeping and use, and on the cost angle, as long as each user has the authentication that a card reader can realize the IC KEY of different bank distribution, because the consumer needs only in relevant client computer the drive software that IC KEY turns the USBKEY card reader is installed simultaneously, need to install a drive software than original each USBKEY or U shield, more convenient simple.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
