Description
Technical field
The present invention relates to a kind of mobile payment testing apparatus and method, particularly relate to the device and method of the intelligent SD card test realizing mobile payment.
Background technology
Mobile payment is also known as mobile-phone payment, be one of focus of current emerging payment technology, its core concept is by closely contactless smart card and mobile phone terminal combine, realize on-site payment function by mobile phone simulated intelligence card, and utilize the network communication of mobile phone to realize remote payment function; Meanwhile, utilize the high security of intelligent card chip to ensure the safety of payment information and payment process.Mobile-phone payment possesses easy-to-use, safety and characteristic efficiently, is the development trend that following e-finance pays.
In mobile payment solution, China Unionpay, telecom operators and Third-party payment company are all proposed in conjunction with the industrial advantage of oneself scheme and product that meet self-growth.Wherein China Unionpay have selected the intelligent SD card scheme not being limited to mobile operator SIM (Subscriber Identity Module) and blocking, and be proposed in 2010 the intelligent SD card only supporting remote payment, within 2011, be proposed again and support that remote payment and near field pay the NFC-SD card of (Near Field Payment) simultaneously, and promulgated relevant technique standard and criterion, just commercially widely popularize at present.
Intelligent SD card, refer to the novel intelligent SD card formed after traditional SD card inside embeds the safety intelligent card chip (SE) of financial level, its framework is as shown in Figure 1; It is under the prerequisite not changing the hardware design of mobile phone own, as long as make mobile phones most on market have the function that SD card slot just possesses mobile-phone payment, thus is beneficial to the expansion of mobile-phone payment business.Intelligent SD card is divided into two kinds, one does not support the SD card of single-wire-protocol (SWP, Single Wire Protocol) interface, and this SD card can be used on the intelligent terminal of any band SD draw-in groove, but it only supports remote payment function, on-site payment function cannot be supported; Another kind is the SD card supporting SWP interface, be called NFC-SD card or SWP-SD card, this SD card can be used in specifically support close range wireless communication (NFC, Near Field Communication) function intelligent terminal on, remote payment and on-site payment function can be supported.
At present, similar protocol conversion device is only limitted to the conversion of physical aspect aspect, kilocalorie (such as mass transit card, interchanger etc.) as ID-1 standard is converted to Plug-in lesser calorie (SIM card as used in regular handset) or 3FF lesser calorie (SIM card of smaller szie as iphone mobile phone uses), this kind equipment is the adaptation conversion of interface form, connecting line adopts the mode directly connected, and does not carry out conversion and the adaptation of software protocol aspect.
Have again, take Unionpay as financial intelligent SD card (abbreviation NFC-SD card or the SWP-SD card) product of the long-range and on-the-spot mobile payment service of support that main body is promoted, this product extends the pin PIN9 that two are exclusively used near field payment interface on SD card original standard pin basis, PIN10, as shown in Figure 1; Wherein, PIN9 is SWP interface, for (the SWP interface of (i.e. non-contact front-end, Contact-Less Front-end) chip is connected with NFC mobile terminal CLF; PIN10 then for connecting power supply, for powering for the chip operation on intelligent SD card.Because PIN9 with PIN10 is directly be connected with intelligent card chip (Smart IC) in SD card inside, not through the process of SD controller on card, therefore conversion and the adaptation of protocol level cannot be carried out.So the needs of some producer in order to test, PIN9, PIN10 and GND of SD card (ground wire) three lines are connected on C6, C1, C5 interface of SIM card, this conversion equipment is also the mode adopting connecting line directly to connect, also conversion and the adaptation of protocol level is not carried out, only can be used in the adaptation test of SWP interface, communication can not be carried out with the ISO7816 interface of smart card in SD card.The feature of above interface conversion equipment is, just carries out the interface conversion of physical aspect, and circuit-line adopts the mode directly connected, and does not carry out the conversion of software protocol aspect, does not also have the participation of main control chip, so, all have some limitations.
As can be seen here, existing intelligent SD card is converted to the interfacing equipment of SIM card, only can realize the conversion of SWP interface, and be the interface conversion of physical aspect, circuit-line adopts the mode directly connected, and does not carry out the conversion of software protocol aspect, does not also have the participation of main control chip.So, cannot the adaptive existing testing apparatus possessing SIM card interface for the intelligent SD card product promoted at present, as TC3 equipment, can not be used in and only support the NFC mobile phone of SWP SIM scheme is tested.Therefore, need to propose a kind of device and method realizing the intelligent SD card test of mobile payment, can by intelligent SD card interface conversion being become from hardware and software protocol level the interface of SIM card, and by mobile phone or the testing apparatus with SIM card interface, intelligent SD card various functions is tested easily.
