Abstract
The invention discloses MicroSD cassette equipment applied in the field of radio frequency, which can effectively solve the problem that radio frequency signals cannot effectively penetrate trough a communication terminal. Radio frequency signals can be effectively transmitted to a non-contact type external card reader by physically connecting radio frequency signals on an SIM (subscriber identity module) card or MicroSD card with radio frequency labels and by matching the cassette-owned radio frequency signal amplifying circuit with the signal request of the external card reader. Signals can be transmitted to the SIM card or MicroSD card through effective connection of the SIM card and MicroSD card. The MicroSD cassette effectively realizes that the mobile communication terminal can be applied in the radio frequency fields such as mobile payment, petty payment and entrance guard control.
Description
Technical field
The present invention relates to the MicroSD deck, particularly have the MicroSD deck of rf signal amplification circuit.
Background technology
REID (the Radio Frequency Identification that comprises contactless integrated-circuit card (IC-card); Hereinafter to be referred as RFID) technological development through more than ten years, be widely used in public transport, the gate inhibition; Small amount payment, fields such as mobile-phone payment.
In recent years, in subway system, logistics management; Article anti-counterfeit, demands such as identification promote down, and the RFID technology is constantly progressive; Use more and more universally, market presses for all kinds of RFID labels and identification equipment, particularly along with the development of mobile communication; Mobile communication terminal has almost become the indispensable portable device of consumer's staff, and integrated multi-purpose trend becomes clear day by day on mobile communication terminal, the developing direction that mobile communication terminal and radio-frequency technique are combined; Also be mobile operator, Unionpay, the market that bank and equipment supplier open up a few days ago energetically.
Receive the influence of Japan and Korea S's mobile-phone payment; Small amount payment and mobile-phone payment are that the field that gets into is expected always by operator and bank; Because can be extraordinary for payment and on-site payment provide solution in real time; The contactless close distance radio frequency technology of setting has broad application prospects, and will unprecedented opportunities be provided for mobile payment and mobile-phone payment industry, will be new developing direction in future and combine portable terminal and a tractor serves several purposes of RFID.
MicroSD deck in conjunction with radio-frequency technique; Be meant on the basis that keeps original MicroSD deck function; On deck, increase by two groups of metal contacts, in order to connecting the radiofrequency signal that sends out from SIM or MicroSD card, and through the connection to these two groups of metal contacts; Discharge signal outside the mobile phone through the rf signal amplification circuit that carries on the deck, thereby solve the problem that radiofrequency signal can not effectively be passed in mobile phone.
Summary of the invention
Technical scheme of the present invention is:
A kind of MicroSD deck that carries rf signal amplification circuit; Through self-contained metal terminal contact point; The radiofrequency signal of connection on SIM or the MicroSD, and amplify radiofrequency signal through the rf signal amplification circuit that carries realizes and the communicating by letter of outside card reader.
Described rf signal amplification circuit is used to amplify the signal of issuing radio-frequency card reader from SIM or MicroSD card.
Described rf signal amplification circuit is used to amplify the radio frequency model of receiving from radio-frequency card reader.
Said rf signal amplification circuit implementation can be active, also can be passive.
Described rf signal amplification circuit can be front, the back side, side and the inside etc. that are embedded in base, anyly avoids this invention through changing its position, all is that to invent spirit therewith contrary.
The described radiofrequency signal binding post that is embedded on the base can be any position that is embedded on the base, anyly avoids this invention through changing its position, all is that to invent spirit therewith contrary.
The described radiofrequency signal binding post that is embedded on the base can change its quantity according to the quantity of actual radio frequency signal demand, anyly avoids this invention through the quantity that changes its binding post, all is that to invent spirit therewith contrary.
When said MicroSD deck is used for RF application and radio-frequency card reader carry out non-contacting communications portion and meet ISO/IEC 14443 standards, ISO/IEC 15693 standards or ISO11784/ISO11785 standard.
The pin that said MicroSD deck connects SIM or MicroSD radiofrequency signal also meets above-mentioned standard.
The rf signal amplification circuit of said MicroSD deck can provide power supply by the terminal equipment of this MicroSD deck of configuration.
Compared with prior art, effect of the present invention is:
Replace existing MicroSD deck with MicroSD deck of the present invention; The radiofrequency signal that can effectively solve transmission and receive is through the problem of signal attenuation behind the mobile phone, when existing radio-frequency card reader sends a command to radio frequency, because the shielding action of battery of mobile phone and circuit board; Signal has very big power attenuation; Rf signal amplification circuit among the present invention carries out signal and amplifies, and cooperates the RF tag of SIM or MicroSD again, just can correctly realize and the communicating by letter of radiofrequency signal card reader.
In addition, both can be used as common MicroSD deck with this MicroSD deck and used, also can be used in RF application, realized mobile-phone payment, small amount payment, the field of radio frequency identification of gate inhibition's control etc. with SIM with RF tag or MicroSD card.
