Abstract
The invention discloses an external smart card reader with a USB (Universal Serial Bus) interface. The external smart card reader comprises a smart card reading device, wherein the card reading device comprises an antenna and a special chip; and the special chip comprises three modules including a high-speed radio frequency interface, a control unit and an EEPROM (Electrically Erasable Programmable Read-Only Memory). The external smart card reader is characterized by comprising a USB interface electrically connected with the control unit. A bus 1 is connected with the three modules including the high-speed radio frequency interface 2, the control unit 3 and the EEPROM 4 to form the special chip, and the special chip and the antenna 5 form the card reading device 6. A shell of the card reading device 6 is provided with a USB slot interface 7 to form the external smart card reader with the USB interface. The card reader is electrically connected with a mobile phone 11 through the USB slot interface 7, a USB plug interface 8 inserted to the USB slot interface 7, a cable 9 and a mobile phone data line interface 10; and the card reader is connected with a smart card 12 through the antenna 5 by means of a signal under the control of the control unit 2.
Description
Technical field
The present invention relates to adopt the external smart card reader of USB interface.
Background technology
Comprise the contact type intelligent card (CICC-Contactless Integrated Circuit Card) of bank card, form by antenna and special chip.Antenna is that the coil of several groups of tinsel coileds is embedded in Ka Jinei, and special chip is made up of high-speed radio-frequency interface, control module, three modules of EEPROM.Card is that information and the exterior read-write equipment in will blocking by electromagnetic induction carries out communication.
Be loaded on the carrier wave of a fixed frequency behind the information coding that noncontact IC card read/write device will send, a resonant circuit is arranged in the card, its frequency is identical with the carrier frequency that read write line sends, enter the perform region of read write line when non-contact IC card after, resonant circuit produces resonance and produces the electric charge accumulation, when electric charge runs up to certain numerical value, just can provide the worker to organize voltage for the circuit in blocking, reset signal, system clock, the data message that read write line sends is through radio frequency interface module decoding in the card, judge the requirement and the rationality of these information by control module, handle then, whether final decision is rewritten or is exported the data in the EEPROM.
Contactless smart card can carry bulk information, but inconvenience reads and exchange message whenever and wherever possible.And existing individual digital equipment comprises that smart mobile phone, panel computer and personal computer do not have the function that directly reads contactless smart card.
Summary of the invention
The objective of the invention is to provide the external smart card reader that adopts USB interface.
The present invention solves the technical scheme of its technical matters: make an external smart card reader that adopts USB interface, comprise the smart card reader device; Described Card Reader device comprises antenna and special chip, and described antenna is the coil that is embedded in the tinsel coiled in the intelligent card matrix; Described special chip comprises high-speed radio-frequency interface, control module and three modules of EEPROM.Adopt a USB interface that is electrically connected with its control module, be electrically connected the realization input and output with the external world.
Can also adopt a USB plug interface that is electrically connected by cable and its control module; A USB slot interface that is electrically connected with its control module perhaps is set on its housing.
Beneficial effect of the present invention: because easy-to-read uses non-contact IC card, non-contact IC card is more widely used, so that reaches the boundary that redefines the non-contact IC card purposes.The user only need by with the card reader of charger integral production, can be whenever and wherever possible and the smart card communication.
Description of drawings
Further be illustrated below in conjunction with drawings and Examples.
Fig. 1 is an external smart card reader theory diagram that adopts USB interface.
Fig. 2 is one and adopts the external smart card reader of USB interface and the connection diagram of a mobile phone and one piece of contactless smart card.
Among the figure, 1. bus; 2. high-speed radio-frequency interface; 3. control module; 4.EEPROM; 5. antenna; 6. Card Reader device; 7. USB slot port; 8. USB plug interface; 9. cable; 10. data in mobile phone line interface; 11. mobile phone; 12. smart card.
Embodiment
Fig. 1 and Fig. 2 provide one embodiment of the invention jointly.
Among Fig. 1 and Fig. 2, connecting high-speed radio-frequency interface 2, control module 3 and EEPROM(nonvolatile read-only memory with bus 1) 4 three modules form a special chip, and special chip and antenna 5 are formed a Card Reader device 6 together.A USB slot interface 7 is set on Card Reader device 6 housings, constitutes an external smart card reader that adopts USB interface.Described card reader is electrically connected with mobile phone 11 by USB slot interface 7, the USB plug interface 8 that inserts USB slot interface 7, cable 9 and data in mobile phone line interface 10; Described card reader is connected with smart card 12 signals by antenna 5 under control module 2 controls.
In the embodiment of the invention, antenna 5 objects such as grade had both referred to a hardware component, were meant a relatively independent circuit again.
Adopt the external smart card reader of USB interface also to relate to software and application program.
Claims (2)
1. adopt the external smart card reader of USB interface, comprise the smart card reader device; Described Card Reader device comprises antenna and special chip, and described antenna is the coil that is embedded in the tinsel coiled in the intelligent card matrix; Described special chip comprises high-speed radio-frequency interface, control module and three modules of EEPROM, it is characterized in that containing a USB interface that is electrically connected with its control module.
