Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
In the embodiment of the present invention, the method for reading information of a smart card provided in the embodiment of the present invention is based on a Radio Frequency Identification (RFID) technology, and is further applied to a Near Field Communication (NFC) technology, and the method may be applied to a card reading device based on an Android system.
The RFID technology is a communication technology that can identify a specific object and read and write related data through a radio signal without establishing a mechanical or optical contact between an identification system and the specific object, and the NFC technology evolved from the RFID technology and is based on the RFID and interconnection technology. NFC is a short range high frequency radio technology that operates within a 10 centimeter distance at a frequency of 13.56 MHz. The transmission speed is 106 Kbit/s, 212 Kbit/s or 424 Kbit/s. Near field communication has passed to become ISO/IEC IS18092 international standard, ECMA-340 standard and ETSI TS 102190 standard. NFC employs both active and passive read modes.
The NFC technology is integrated and evolved from RFID and interconnection technology, and can be used for carrying out identification and data exchange with compatible equipment in a short distance by combining the functions of an induction type card reader, an induction type card and point-to-point on a single chip. The operating frequency was 13.56 MHz.
The android system is a mobile terminal system widely applied in the current market, and gives a user a relatively open right. At present, mobile payment services are developed vigorously, an NFC module is usually built in a mobile terminal applying an android system, so as to support the mobile terminal to perform processing of services such as mobile phone payment and bank card recharging.
Referring to fig. 1, a flow chart of steps of a smart card information reading method is shown.
In step 110, the current smart card type is determined by the smart card information reading device.
In the step, the mobile terminal calls an NFC interface function of the mobile terminal, the NFC module is started, the NFC module conducts electromagnetic field coupling induction on the smart card in the card induction area in an electromagnetic field coupling mode, energy supply to the smart card and signal exchange on the smart card are completed, namely an integrated circuit and a coupling tool are arranged on the smart card, and a micro-electric element is not required to be in contact with the smart card. NFC reads the characteristic data of the smart card through electromagnetic field coupling, analyzes the characteristic data of the smart card, and judges the type of the current smart card according to the matching of the analysis result and the type of the smart card in the technical standard.
Optionally, in the embodiment of the present invention, the current smart card supports the contactless integrated circuit IC card standard protocol (ISO 14443). The protocol consists of four parts, the first part: a physical property; a second part: spectral power and signal interface functions; and a third part: initializing and anti-collision algorithm; the fourth part: and (4) communication protocol. The protocol comprises ISO14443-A and ISO14443-B which correspond to application specifications of a first type of smart card and a second type of smart card respectively, and the ISO14443-A is mainly applied to the fields of production automation, access control and attendance checking, security protection, one-card and product anti-counterfeiting and the like, is generally used for access control cards, bus cards, small-amount stored value consumption cards and the like, and has high market share. ISO14443-B is more suitable for CPU cards due to higher encryption coefficient, and is generally used for identity cards, passports, union pay cards and the like, and the current standard adopted by the second generation electronic identity cards is the ISO14443-B protocol. In the embodiment of the invention, the current smart card is determined to be the first type card or the second type card through judging the type of the current smart card, and further, the current smart card is determined to be the card in the specific field in the corresponding type.
And step 120, calling a reading logic corresponding to the current smart card according to the type of the current smart card, and reading the card information of the current smart card.
In this step, after the type of the current smart card is determined, a reading logic corresponding to the current smart card is called to read the service data in the current smart card, and the card information includes data required by the current service processing performed by the smart card.
For example: when a user needs to perform subway card recharging service, the recharging application is opened, the subway card is placed on the back of the mobile phone and is in contact with the NFC module of the mobile phone, the NFC module reads characteristic data of the subway card through electromagnetic field coupling, the current subway card is judged to be the first type card, the basic data of the subway card can be displayed, and the recharging application receives the data of the subway card and completes recharging of the subway card through the server.
In summary, the embodiment of the present invention provides a method for reading information from a smart card, in which a smart card information reading device first determines a current smart card type, and then invokes a reading logic corresponding to the current smart card to read card information of the current smart card, so as to perform subsequent service processing. The invention realizes the integrated process of identifying and reading various intelligent cards by identifying and reading various different types of intelligent cards, solves the problem that only a single intelligent card can interact with a single card reading terminal in the prior art, and improves the reading efficiency.
Example two
Referring to fig. 2, a flow chart of specific steps of a smart card information reading method is shown.
And step 210, calling a feature data extraction interface function, and extracting the feature data of the current smart card.
In this step, the smart card has its feature data built into a preset storage location in the smart card chip during the manufacturing process, and the feature data includes basic data such as a naming file and a type data file of the smart card based on the ISO14443 standard, and it is possible to determine which smart card is the current smart card. After the NFC equipment carries out electromagnetic field coupling to the current smart card, the chip of the smart card obtains energy, and carries out data exchange with the NFC equipment, and the NFC equipment obtains characteristic data transmitted by the smart card.
In this step, the NFC device determines that the current smart card is the first type card or the second type card by analyzing the current smart card feature data.
Optionally, step 220 may further include sub-steps 2201, 2202.
Substep 2201, generating a corresponding characteristic label according to the characteristic data of the current smart card.
Specifically, in the substep, the NFC device may be applied to an android system, and according to the specification and standard of an NFC module of the android system, after the NFC module reads the feature data of the smart card, the NFC device may generate a corresponding feature tag in the system according to the feature data, and the Activity process of the NFC module may process the feature tag, so that the feature tag may provide a read-write segment or perform some operations. Of course, the present application is applicable to other operating systems that employ similar principles.
A sub-step 2202 of determining the type of the current smart card according to the tag name of said feature tag.
In the sub-step, the feature tag generated by the NFC module is based on the type of the current smart card, and has a corresponding tag name, that is, the first type smart card corresponds to a fixed first type tag name, the second type smart card also corresponds to a fixed second type tag name, and the NFC module may determine the type of the current smart card through the processor according to the tag name.
Optionally, the sub-step 2202 may further include a sub-step 22021, a sub-step 22022.
In sub-step 22021, if the name of the generated feature tag is, for example, android.

In step 230, if the type of the current smart Card is the first type, an information reading interface function (e.g., get Card Info interface function) of the current smart Card is called, and the Card information of the current smart Card is read.
In the step, if the current smart Card is judged to be of the first type, a get Card Info interface function of the smart Card is called according to an ISO14443-A protocol, and Card information of the current smart Card is read.
It should be noted that the first type Card is generally an access Card, a bus Card, a small-value stored-value consumption Card, and other smart cards, and the security level of the first type Card is lower than that of the second type Card, so the first type Card has a general get Card Info interface function, and the NFC device can call the interface function to read and write data of the smart Card.
And 240, if the type of the current smart card is the second type, calling an interface function of an information reading software development kit corresponding to the current smart card, and reading card information of the current smart card.
In this step, the second type of card is more suitable for CPU cards, typically for identification cards, passports, union pay cards, etc., due to the higher encryption factor. Because the security level is higher, the smart Card does not open get Card Info interface function, and data reading and writing are carried out on the smart Card through a corresponding third-party smart Card information reading software development kit. The third-party smart card information reading software development kit is authorized by governments and application manufacturers, and has a high secret coefficient.
Optionally, step 240 may further include substep 2401, substep 2402, substep 2403.
Substep 2401, if the type of the current smart card is a second type, calling a feature tag analysis interface function, and analyzing the content of the feature tag.
Specifically, the feature tag file stores feature data of the smart card, such as a name file and a feature data file, and by analyzing the feature tag, which smart card the current smart card is specific to can be determined.
Substep 2402, determining that the current smart card is a specific type of the second type smart card according to the analysis result of the feature tag content.
For example: analyzing the characteristic label of a certain second type card to obtain an analysis result, and judging that the second type card is a second-generation identity card according to an ISO14443-B protocol.
Substep 2403, calling an interface function of the information reading software development kit corresponding to the current smart card, and reading the card information of the current smart card.
And step 250, after the card information of the current smart card is successfully read, uploading the card information of the current smart card to a third-party application.
Step 250 specifically includes:
substep 2501, determining whether the reading of the current smart card information is successful.
After step 240 is completed, it is detected whether the NFC module receives the card information of the current smart card, and whether reading of the card information of the current smart card is successful is determined. And if the reading is successful, returning the card information of the current smart card.
Specifically, after the reading is successful, the NFC module may upload the received card information of the current smart card to the processor and display the card information on the screen of the mobile terminal, so that the card information can be read by the user.
Further, if the mobile terminal is performing service processing on the current smart card, the NFC module uploads the card information of the current smart card to a third-party application after the card information is successfully read.
Meanwhile, after the card information of the current smart card is successfully read, the NFC module can upload the received card information of the current smart card to the processor and display the card information on a screen of the mobile terminal for a user to read.
And a substep 2502, wherein the third party application processes the service of the current smart card according to the card information of the current smart card.
For example, when a user needs to perform a subway card recharging service, the recharging application is opened, the subway card is placed on the back of the mobile phone and is in contact with the NFC module of the mobile phone, the NFC module reads characteristic data of the subway card through electromagnetic field coupling, the current subway card is judged to be a first type card, basic data of the subway card can be displayed, and the recharging application receives card information of the subway card and completes recharging of the subway card through the server.
And if the reading fails, returning reading failure information.
In this step, if the reading fails, the NFC module may upload the reading failure information to the processor and display the reading failure information on the screen of the mobile terminal for the user to read.
In summary, an embodiment of the present invention provides a method for reading information from a smart card, in which a smart card information reading device first determines a feature tag generated in a system of a current smart card, determines a type of the current smart card, then invokes a reading logic corresponding to the current smart card, reads card information of the current smart card, and uploads the card information to a third-party application for subsequent service processing.
