Description

A kind of external NFC module for smart mobile phone
Technical field
This utility model belongs to smart mobile phone innovation and application field, is specifically related to a kind of external NFC module for smart mobile phone.
Background technology
NFC technology is to be developed by non-contact radio-frequency identification and the Technology Integration that interconnects, and combining induction card reader, vicarious card and point-to-point function on one chip can be identified with compatible equipment and data exchange in short distance.The equipment supporting NFC can exchange data under actively or passively pattern.In the passive mode, start the equipment of NFC communication, also referred to as NFC initiating equipment, whole communication process provides radio-frequency field.It can select 106kbps, 212kbps or 424kbps one of which transmission speed, transmits data to another equipment.Another equipment is called NFC target device, it is not necessary to produces radio-frequency field, and uses load-modulate technology, namely identical speed can pass data back initiating equipment.NFC mobile phone refers to the mobile phone with NFC module, and the mobile phone with NFC module can do a lot of corresponding application.For there is no the mobile phone of built-in NFC module, just cannot realize near field communication (NFC) function, if wanting to realize this technology, it is necessary to connect a NFC module in outer handset.
Utility model content
The purpose of this utility model is in that to provide a kind of external NFC module for smart mobile phone to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose: a kind of external NFC module for smart mobile phone, including cell-phone cover, NFC module installs set, pcb board, data wire, in described cell-phone cover, smart mobile phone is installed, the design of the described cell-phone cover back side has described NFC module to install set, described NFC module is installed set and is placed with described pcb board, described data wire is connected between described smart mobile phone and described pcb board, the surface configuration of described pcb board has vicarious card reader, it is provided with NFC file module inside described vicarious card reader, described pcb board central authorities are provided with control chip, described control chip connects encrypting module, described encrypting module connects antenna again.
In said structure, described smart mobile phone is packed in described cell-phone cover, described pcb board is packed into described NFC module and installs in set, during use, the two is coupled together by described data wire, under the control of described control chip, described vicarious card reader is connected with extraneous wireless device, reads data message, from described NFC file module after described encrypting module is encrypted, launch from described antenna, when not using, described data wire is extracted, put described NFC module into and install in set.
In order to increase near-field communication technology to regular handset, in the compacted described cell-phone cover being arranged on rubber of described smart mobile phone, described NFC module is installed set and is generated by injection molding manner is integrated with described cell-phone cover, it is open type design that described NFC module installs the top of set, described pcb board is compacted to be arranged in described NFC module, and the plug of described data wire is respectively connected to the data-interface of described smart mobile phone and the data-interface of described pcb board end.
In order to increase near-field communication technology, the internally installed wireless data signal reading device of described vicarious card reader for regular handset, being fixed by screws in the surface of described pcb board, described NFC file module connects described vicarious card reader by holding wire.
In order to increase near-field communication technology for regular handset, described control chip is embedded in described pcb board central authorities, and connect other modules by signal line, the data-interface intercommunication of described control chip data wire and described encrypting module, described encrypting module accesses the input of described antenna by holding wire.
Have the beneficial effects that: can be common smart mobile phone increase near-field communication technology, and the small volume of external connection module, use without influence on mobile phone.
