Technical field
The utility model relates to intelligent card reader field, is specifically related to a kind of WIFI two interfaces intelligent card reader.
Background technology
Card reader (Reader) is a kind of card-reading apparatus, because kind of cards is more, so the implication coverage of card reader is wider.According to the difference of type of card, IC-card card reader can be divided into, be comprised Contact Type Ic Card, be followed ISO7816 interface standard; Contactless IC Card Reader, follows ISO14443 interface standard, remote card reader, follows ETC GB GB20851 interface standard; Divide by port type and can be divided into serial port card reader, parallel port card reader, USB card reader.
The interface of traditional double interface card reader is USB port or serial ports; Be connected with PC by these two interfaces, the application software of being held by PC carries out read-write operation to contact card or non-contact card; But along with popularizing of smart mobile phone, and the rise of mobile payment, there is many application scenarioss, need card reader and mobile phone to carry out communication.
The mode generally adopted at present is bluetooth and audio interface: voice communication is unstable, and can not effectively support for high speed data transfer; Bluetooth card reader is then difficult to the diversity supporting current Bluetooth of mobile phone interface.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of WIFI two interfaces intelligent card reader, and this card reader interface standard is unified, can meet the multifarious demand of mobile phone; WIFI communication speed is high, can meet the requirement of two-forty.
For reaching above object, the technical solution of the utility model is: a kind of WIFI two interfaces intelligent card reader, comprises WIFI module, card reader module, power management module for managing electrical power;
Described card reader module comprises: the Master control chip be connected with non-contact card read-write chip with contact card read-write chip respectively; Described WIFI module is connected with Master control chip; Power management module controls the constrained input of power supply, and wherein, the input end of power management module connects chargeable lithium cell respectively and is connected WIFI module and card reader module respectively with the output terminal of USB interface, power management module.
Further, described non-contact card Card Reader chip is connected with noncontact antenna.
Further, described contact card read-write chip is connected with contact deck.
Further, described WIFI module is connected with WIFI antenna.
Effect of the present utility model is: after adopting the utility model technology, WIFI communication speed is high, meets the requirement of two-forty; Interface standard is unified, can meet collection diversity requirement; Use WIFI interface can also realize Long-distance Control card reader in addition.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
Be illustrated in figure 1 the two interfaces of a kind of WIFI disclosed in the utility model intelligent card reader, comprise WIFI module, card reader module, power management module for managing electrical power; Described card reader module comprises: the Master control chip be connected with non-contact card read-write chip with contact card read-write chip respectively; Described WIFI module is connected with Master control chip; Power management module controls the constrained input of power supply, and wherein, as shown in Figure 4, the input end of power management module connects chargeable lithium cell respectively and is connected WIFI module and card reader module respectively with the output terminal of USB interface, power management module.
Wherein, described lithium battery built-in interfaces two with WIFI intelligent card reader, meets portability demand, can complete the operation of smart card related application by matching with mobile phone; WIFI double-interface smart card card reader leaves USB interface, and this interface can be used as to lithium cell charging interface, can also directly use as card reader power supply.
Described contact card read-write chip is provided with contact deck, to have contacted the digital independent between smart card and card reader by contact deck with intelligent card chip sensing part; Described non-contact card read-write chip is provided with noncontact antenna, completes read-write operation by the radiowave between smart card and card reader.
WIFI module is also provided with the WIFI antenna for strengthening WIFI signal intensity.
Preferred: WIFI module is HF-LPB100Wifi module, as shown in Figure 3; Master control chip model is STM32, as shown in Figure 2; Contact card read-write chip model is AU9541, as shown in Figure 6; Non-contact card read-write chip model is AS3911, as shown in Figure 5.
During use, the Master control chip in card reader module receives the smart card information data of non-contact card and contact card reading, and the information data of reading is passed to WIFI module by Master control chip.
WIFI module and the equipment connection being loaded with WIFI function, the equipment of WIFI function is coordinated to complete the operation of smart card related application (as realized the reading of intelligent card data, Long-distance Control card reader etc.), wherein said equipment is the mobile phone with WIFI function, or be connected with intelligent card reader with the PC of WIFI function, complete application of IC cards, in the present embodiment, smart card be satisfied 7816 with the contacting or contactless smart card of 14443 standards.
It can thus be appreciated that this function makes there has been related application in the application system of PC without the need to change at some, and only need change interface can use, and relative to bluetooth or audio frequency card reader, can only apply at mobile phone terminal, WIFI double-interface smart card card reader has more advantage.
It will be understood by those skilled in the art that device described in the utility model is not limited to the embodiment described in embodiment, specific descriptions above, just in order to explain the purpose of this utility model, are not for limiting the utility model.Those skilled in the art draw other embodiment according to the technical solution of the utility model, and belong to technological innovation scope of the present utility model equally, protection domain of the present utility model is by claim and equivalents thereof.
