Abstract
The utility model provides an intelligent secure digital memory (SD) card close range magnetic field payment adapter based on 13.56 megahertz (MHz). The intelligent SD card close range magnetic field payment adapter based on 13.56 MHz comprises an intelligent card chip, an SD module and a near field communication (NFC) radio frequency module of 13.56 MHz. The intelligent card chip is provided with an International Standardization Organization (ISO) 7816 slave interface used for contacting and communicating with an International Standardization Organization (ISO) 7816 interface of a payment terminal, the intelligent card chip is connected with the SD module through a serial peripheral interface (SPI), and the SD module is connected with the NFC radio frequency module of 13.56 MHz through a single wire protocol (SWP) interface. The intelligent SD card close range magnetic field payment adapter based on 13.56 MHz enables a bank or a Unionpay to achieve contact application download and financial payment transactions on the condition that no equipment needs to be transformed, and clients can use the adapter to carry out close range financial payment transactions with no contact.
Description
Technical field
The utility model relates to the mobile communication technology field, is specifically related to a kind of intelligent SD card based on 13.56MHz and closely pays the adapter of namely supporting contact and contactless financial transaction in magnetic field.
Background technology
Arrival along with the 3G epoch, mobile payment becomes most important payment and settlement mode, it is to allow the user to use its portable terminal (normally mobile phone) that a kind of method of service that account is paid is carried out in commodity or the service of consuming, and can carry out on-the-spot small amount payment, wholesale payment, remote payment and bank card inquiry into balance.
The mobile payment technology mainly contains at present:
1, two interface JAVA Card: two interface C PU cards are a kind of CPU cards of supporting simultaneously contact and contactless two kinds of communication modes, and the public CPU of contact interface and non-contact interface controls, contact and contactless automatic selection.Shortcoming: different two interface chips, need the different antenna line coil of coiling, can't use intelligent SD card thereon.
2,13.56MHz SIMPass technology: it is a kind of multi-functional SIM card, supports the function of SIM card function and mobile payment, and SIMPass runs in the mobile phone, for solving the required problem of noncontact face work, needs custom-made mobile phone and low cost antenna assembled scheme.Shortcoming: the user need to use custom-made mobile phone, and as using the antenna assembled scheme, soft PCB antenna is easily lost, and 13.56MHz frequency penetration capacity is poor, can't penetrate the mobile phone metal shell.
3, RFID-SIM(2.4GHZ): intelligent chip and 2.4GHZ combination realize closely payment.Shortcoming: closely control is difficult, does not have unified international standard, and each manufacturer's standard is different.
4, NFC technology: NFC embedded in mobile phone NFC chip, form a RFID module part, can use as RFID.Shortcoming: the client need to change existing mobile phone, uses the NFC mobile phone.
5, intelligent SD card: the EEPROM capacity of SIM card reaches capacity now, uses intelligent SD card to enlarge the SIM card capacity, needs custom-made mobile phone to solve closely payment.Shortcoming: the user need change mobile phone, can't satisfy payment services merchant (as: bank, Unionpay) contact and use.
The utility model content
In view of this, be necessary the problem mentioned for background technology, provide a kind of communication efficiency well and can realize the closely device of transaction payment.
The purpose of this utility model is achieved through the following technical solutions:
A kind of intelligent SD card based on 13.56MHz is closely paid adapter in magnetic field, it is characterized in that: it comprises an intelligent card chip, a SD module and a NFC radio-frequency module, described intelligent card chip has for contacting the ISO7816 of communication from interface with the ISO7816 interface of payment terminal, described intelligent card chip is connected by the SPI interface with described SD module, and described SD module is connected by the SWP interface with described 13.56MHz NFC radio-frequency module.
Compared with prior art, the utility model possesses following advantage: the utility model downloads to the data of 7816 interfaces among the intelligent and safe module SE of intelligent SD card by spi bus, closely pay, make bank, Unionpay is not in the situation that need to transform any equipment, realize contact application download, the financial payment transaction, the client can carry out closely financial payment transaction with this adapter under contactless, NFC radio-frequency module Main Function comprises in contactless application: NFC is near field communication (NFC), it is a kind of contactless identification and interconnection technique, can be at mobile device, consumer terminal is carried out the near radio payment transaction.This intelligent SD card also can insert in the custom-made mobile phone, closely reaches long-range financial payment transaction, and convenient and practical, generalization is strong.
Description of drawings
Fig. 1 is the modular structure schematic diagram of the utility model and payment terminal UNICOM.
Embodiment
As shown in Figure 1, the present embodiment provides a kind of intelligent SD card based on 13.56MHz closely to pay adapter in magnetic field, it comprises an intelligent card chip, a SD module and a 13.56MHz NFC radio-frequency module, described intelligent card chip has for the ISO7816 that contacts communication with the ISO7816 interface of payment terminal from interface, described intelligent card chip is connected by the SPI interface with described SD module, described SD module is connected by the SWP interface with described 13.56MHz NFC radio-frequency module, and described 13.56MHz NFC radio-frequency module connects antenna.
During payment, described adapter is contacted with described payment terminal, the ISO7816 of described intelligent card chip contacts with the ISO7816 interface of payment terminal from interface and receives payment data, described SD module is not shown with the intelligent and safe module SE(that described payment data is transferred to intelligent SD card by described SPI interface) in, closely pay, make bank, Unionpay is not in the situation that need to transform any equipment, carry out contact and use download, the financial payment transaction, the client can carry out closely financial payment transaction with this adapter under contactless, NFC radio-frequency module Main Function in contactless application: NFC is near field communication (NFC), it is a kind of contactless identification and interconnection technique, can be at mobile device, consumer terminal is carried out the near radio payment transaction.This intelligent SD card also can insert in the custom-made mobile phone, closely reaches long-range financial payment transaction.
