Description
Technical field
The present invention relates to E-Payment field, relate in particular to a kind of method and a kind of system that realizes Card Reader operation that realizes Card Reader operation.
Background technology
Use passive RFID (Radio Frequency Identification, the radio-frequency (RF) identification) technology of 13.56MHz very ripe.The magnetic field of the 13.56MHz that the passive RFID card of 13.56MHz sends from card reader, obtain the work energy, not needing provides power supply to get final product work in addition, completes the operation of E-Payment.Such as the mass transit cards that use in a large number at present.The form of the card reader antenna coil of this mode has determined the characteristic that the magnetic field energy of 13.56MHz decays rapidly with the increase of the distance of card reader along with card, i.e. near field characteristic.Near field characteristic is: 3 powers of magnetic field intensity and distance are inversely proportional to.Thereby the passive RFID card that makes 13.56MHz during from card reader larger distance, can not obtain enough energy, thereby realize the object that distance is controlled from magnetic field, and general distance is controlled and required to be less than 10cm for operating distance.
At present, the solution of the mobile terminal payments such as existing various mobile phones is not overripened, has various shortcomings, is unfavorable for promoting the use of.Mainly contain following 5 kinds of schemes.
Scheme 1: stick the RFID signal repeat circuit pasting card of a 13.56MHz on mobile phone, the SIM card in mobile phone, card reader have coordinated the operation of mobile-phone payment.Between RFID pasting card and card reader, use 13.56MHz communication, the RFID pasting card while is used higher radio-frequency communication with the sim card in mobile phone, such as using the frequency range of 2.45GHz.Can not Direct Communication between card reader and sim card, by the communication of RFID pasting card bridges forward.The 13.56MHz RFID technology of maturation can not need the support of sim card to complete separately payment function at present, such as conventional mass transit card.RFID pasting card just can complete separately payment function originally.In order to allow SIM cards of mobile phones support payment function, transform by force sim card and pasting card, sim card can be seen through the forwarding of RFID pasting card and realize mobile-phone payment function.If mobile phone with metal shell, pasting card can only be affixed on the outside surface of phone housing, just can normally use, and pasting card easily weares and teares destroyed.Because sim card in RFID pasting card and mobile phone is used higher radio-frequency communication, for fear of RFID pasting card and other mobile phone around, carry out communication, cause mobile-phone payment maloperation, need to bind sim card and RFID pasting card.When user changes mobile phone, when original sim is snapped fits into new cell-phone, RFID pasting card need to be torn it down and be affixed on new mobile phone, there is very large integrity problem in this operation.When user changes mobile phone, or use to buy new RFID pasting card, then need an operation, allow sim card and new RFID pasting card bind.
Scheme 2: the improvement of scheme 1.On mobile phone, stick the RFID pasting card of a 13.56MHz, RFID pasting card only with card reader communication, RFID pasting card is not interrogated with sim cartoon.Card reader reads ID from RFID pasting card, card reader is interrogated by higher radio frequency and sim cartoon, whether the ID that sim card checking card reader is read is and the own ID binding, if, just carry out follow-up business, thereby realize distance by RFID pasting card, control, sim cartoon is crossed radio frequency directly and card reader communication realizes delivery operation.This scheme RFID pasting card does not need to bear the work of bridges forward communication, do not needed the operation of payment yet, simplified RFID pasting card circuit, reduced the electrical source consumption of RFID pasting card, made to obtain enough work capacities the magnetic field of its 13.56MHz more easily providing from card reader.But its shortcoming is the same with scheme 1.
Scheme 3:NFC scheme.It is unique scheme that obtains International Standard Association's approval.NFC scheme is used the signal of 13.56MHz, and card reader is by cell phone mainboard and SIM card communication or direct and SIM card communication.On mobile phone, be designed with the signal transmitting and receiving antenna of 13.56MHz.NFC needs custom-made mobile phone, and restricted to the structural design of mobile phone, is unfavorable for designing the mobile phone of various styles, promotes the use of and must change mobile phone.
Scheme 4: principle is identical with NFC scheme, just by the aerial coil in NFC custom-made mobile phone, changes into and on mobile phone, increases dual-mode antenna coil, dual-mode antenna coil directly and sim link and connect.The reliability existing problems of the dual-mode antenna coil increasing.
The scheme of scheme 5:RFID-SIM card.Sim cartoon is crossed radio frequency directly and card reader communication, and card reader is measured the field intensity transmitting of sim card, judges the distance of mobile phone according to field intensity value.The distance of this scheme mobile phone and card reader is controlled inaccurate, distance that can not cocksure control delivery operation.
Therefore, in existing various mobile payment solutions, all there is to some extent the problem of poor reliability.

Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
First illustrate, the method of using the present invention to realize Card Reader operation is carried out the mobile terminal of mobile payment and first will be calibrated, the method that mobile terminal after calibration just can be used the present invention to realize Card Reader operation is carried out mobile payment, and about the method for calibration and process, we illustrate in the back.
The method that the present invention realizes Card Reader operation comprises the following steps:
The present invention realizes and in the method for Card Reader operation, requires in mobile terminal, to have double frequency SIM card, so-called double frequency SIM card refers to the SIM card that can communicate with two kinds of frequencies, using two kinds of frequencies is mainly the consideration based on mobile payment function, wherein a kind of frequency is controlled for the distance of mobile payment, avoid swiping the card by mistake, another kind of frequency is used for communicating by letter, and comprises delivery operation etc.Setting reading range can be preset by the system that realizes Card Reader operation, such as being set as apart from reader device 10cm.
Wherein, first frequency is in high frequency HF frequency range, such as being general 13.56MHz.
The reader device here just refers to various card reader, such as electronic marketing terminal POS (point of sale) machine etc.
Wherein, the threshold value of swiping the card obtains by calibration, double frequency SIM card packs into after mobile terminal, need to carry out once and only needing primary calibration, the magnetic field intensity that obtains the first frequency wireless signal threshold value (herein referred to as the threshold value of swiping the card) of swiping the card, the later operation of swiping the card no longer needs calibration.
Wherein, second frequency is higher than first frequency, and second frequency is in very high frequency(VHF) VHF, superfrequency UHF or ultrahigh frequency SHF frequency range, such as being 2.45GHz, lower same, repeats no more.Between double frequency SIM card and reader device, use the wireless signal of second frequency to set up communication channel.
Illustrate calibration below.Although the magnetic field intensity that in mobile terminal, double frequency sim card detects, along with and reader device between distance to increase decay very fast, be easy to realize the distance control of about 10cm, but the structure of different mobile terminal is not identical, the shielding attenuation amount of the field signal that clamping is received to double frequency sim is not identical, so different mobile terminals need to be set the different magnetic field intensitys threshold value of swiping the card.The magnetic field intensity detecting when double frequency sim card just starts the delivery operation of mobile terminal when being greater than and swiping the card threshold value.While changing mobile terminal, also need double frequency sim card that the new threshold value of swiping the card is set.Calibration is exactly the process that the threshold value of swiping the card that double frequency sim card is new is set.
The ultimate principle of mobile terminal calibration is: mobile terminal is affixed on reader device (or special-purpose calibrating device), allow distance of mobile terminal reader device (or special-purpose calibrating device) recently, the magnetic field intensity of the wireless signal of reader device (or the special-purpose calibrating device) transmitting that the double frequency sim card test of mobile terminal now receives, deducts a magnetic field intensity surplus (i.e. default field intensity surplus) by the magnetic field intensity recording again and obtains magnetic field intensity threshold value.Magnetic field intensity surplus is when guaranteeing that mobile phone is slightly far away apart from card reader, but magnetic field intensity while being less than the distance of about 10cm is also greater than the adjusted value of magnetic field intensity threshold value.
Can be mutual by interface module and mobile terminal after double frequency sim card electrification reset, read the IMEI(International Mobile Equipment Identity of mobile terminal, International Mobile Equipment Identity code) number, the IMEI number of different mobile terminals is different.Double frequency sim card read after the IMEI number of mobile terminal with card in the IMEI number of storage compare, if not identical, the mobile terminal that has just been judged to be double frequency sim card replacement or use for the first time mobile terminal, just the operation of forbidding swiping the card, startup calibration operation.After calibration operation completes, the IMEI number of the mobile terminal reading is deposited in card, for next time, when powering on, start whether needs to start the relatively judgement data source of calibration, the IMEI number of even preserving in double frequency sim card is consistent with the IMEI number of current this double frequency sim card place mobile terminal, do not need calibration, otherwise will calibrate.
Calibrating mode can have a lot, and we provide two kinds of calibrating modes here: automatic calibration mode and professional calibrating mode.Certainly, as long as can realize the object of setting the threshold value of correctly swiping the card, can adopt other any calibrating mode.
Automatic calibration mode can comprise the steps:
Step 11, the wireless test signal strength value that the first frequency of reader device transmitting detected without the double frequency SIM card in the mobile terminal of calibration reaches after setting effective value, to reader device, sends automatic calibration request, starts calibration;
The setting effective value is here through testing the threshold value of swiping the card of a large amount of various model mobile terminals, the minimum value of the threshold value of swiping the card of these model mobile terminals that come out.Double frequency SIM card is used wireless signal and the reader device of second frequency to set up communication channel, sends automatic calibration request.
Step 12, reader device is received after automatic calibration request, detect mobile terminal and the distance between self, search simultaneously sets in reading range whether have calibrated mobile terminal, if without judging whether unregulated mobile terminal and the distance between self are less than the calibrated distance of setting;
The method that reader device is realized distance monitoring is a lot, such as using any in following: radio-frequency echo wave detection, ultrasound examination, change of magnetic field strength detection etc.
Reader device, carrying out searching in setting reading range whether have the calibrated mobile terminal while when distance detects, if had, just stops this calibration operation, to avoid mistake calibration.If be greater than the threshold value of swiping the card and will start the communication with reader device because the double frequency sim card in calibrated mobile terminal detects the magnetic field intensity of the first frequency wireless test signal of reader device transmitting, thus with the reader device operation of swiping the card.
Step 13, if the distance between mobile terminal and reader device self is less than the calibrated distance of setting, reader device notifies double frequency SIM card in this mobile terminal to detect the field intensity value of the wireless test signal of the first frequency receiving;
Step 14, the difference of described double frequency SIM card after the first frequency wireless signal field value recording deducts default field intensity surplus is stored in self as the threshold value of swiping the card of self.
Default field intensity surplus is when guaranteeing that distance of mobile terminal reader device is slightly far away, but magnetic field intensity while being less than the distance of reading range (such as 10cm) of setting is also greater than the adjustment amount of the threshold value of swiping the card.
The double frequency sim card of realizing after automatic calibration can also be recorded the IMEI number of this mobile terminal, whether needs to carry out the judgement of automatic calibration while operating for later mobile payment.Be specially: if the IMEI number of the IMEI number of storing in double frequency SIM card and this double frequency SIM card place mobile terminal is consistent, do not need calibration, otherwise need calibration.After automatic calibration, double frequency sim card and card reader start normal mobile payment operation immediately, allow the process of the imperceptible calibration of user, and whole user's use procedure is as the process of normally swiping the card.
Specialty calibrating mode can comprise the steps:
Step 21, the in the situation that of mobile terminal electric power starting, is placed on mobile terminal on calibrating device, starts calibration;
When user uses new double frequency sim card, or when more renewing mobile terminal and using original double frequency sim card, only need open after the power supply of mobile terminal, mobile terminal is placed on special-purpose calibrating device.Then press on special-purpose calibrating device startup calibration knob start calibration.
Step 22, the wireless test signal of calibrating device transmitting first frequency, calibrates communications protocol information by the wireless signal of second frequency to the double frequency SIM card transmission of mobile terminal;
Such as first frequency can be 13.56MHz.
Step 23, the double frequency SIM card of mobile terminal is received after calibration communications protocol information, detects the field intensity value of the first frequency wireless test signal receiving;
Step 24, the difference of double frequency SIM card after the first frequency wireless test signal strength value recording deducts default field intensity surplus is stored in self as the threshold value of swiping the card of self.
The double frequency sim card of realizing after calibration can also be recorded the IMEI number of this mobile terminal, whether needs the judgement of calibrating while operating for later mobile-phone payment.Be specially: if the IMEI number of the IMEI number of storing in double frequency SIM card and this double frequency SIM card place mobile terminal is consistent, do not need calibration, otherwise need calibration.Whole calibration process just can complete in about 3 seconds, and after having calibrated, calibrating device can, by LED and the sound-producing device of man-machine interface, send acousto-optic hint signal.
