Embodiment 1

[0021] In the embodiment of the present invention, a smart card information reading method provided by the embodiment of the present invention is based on radio frequency identification (English: Radio Frequency Identification, referred to as: RFID) technology, and is further applied to near field communication (English: Near Field Communication , referred to as: NFC) technology, the method can be applied to card reading devices based on Android (English: Android) system.

[0022] RFID technology is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets, while NFC technology evolved from RFID, based on RFID and interconnect technology. NFC is a short-range high-frequency radio technology that operates at a frequency of 13.56MHz within a distance of 10cm. Its transmission speed has three kinds: 106Kbit / s...

Embodiment 2

[0034] refer to figure 2 , which shows a flow chart of specific steps of a smart card information reading method.

[0035] Step 210, calling the feature data extraction interface function to extract the feature data of the current smart card.

[0036] In this step, the smart card has built its feature data into the preset storage location in the smart card chip during the manufacturing process. The feature data includes basic data such as the naming file and type data file of the smart card based on the ISO14443 standard. Through the basic data It can be determined which smart card the current smart card is specifically. When the NFC device performs electromagnetic field coupling to the current smart card, the chip of the smart card obtains energy and exchanges data with the NFC device, and the NFC device obtains the characteristic data transmitted by the smart card.

[0037] Step 220: Determine the type of the current smart card according to the feature data of the current...

Embodiment 3

[0071] refer to image 3 , which shows a flow chart of specific steps of another smart card information reading method.

[0072] Step 310, read the specified byte in the specified sector of the current smart card.

[0073] In this step, the smart card based on the ISO1443 protocol is divided into a plurality of storage sectors in the chip storage area of ​​the smart card according to the protocol requirements, and the characteristic data of the smart card is recorded in the designated sector, and its characteristic data segment can be, for example, The first byte in sector 0.

[0074] Step 320: Determine the type of the current smart card according to the specified byte in the specified sector of the current smart card.

[0075] In this step, after the NFC device receives the data of the specified sector of the current smart card, it judges the specified byte in the sector data, and according to the protocol specification, the type of the current smart card can be judged.

Abstract

The invention provides an intelligent card information reading method and apparatus. The method comprises the steps of judging the type of a current intelligent card by the intelligent card information reading apparatus; and according to the type of the current intelligent card, calling reading logic corresponding to the current intelligent card, and reading card information of the current intelligent card. By identifying and reading multiple different types of intelligent cards, the identifying and reading integrated process for the intelligent cards is realized, so that the problem that only a single intelligent card and a single card reading terminal can interact in the prior art is solved and the reading efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular to a method and device for reading smart card information. Background technique [0002] With the development of computer communication technology, electronic smart cards, such as ID cards and bank cards, have been endowed with the function of connecting with the Internet, and are widely used in telecommunications, transportation, finance and other fields. [0003] The smart card and the card reader terminal identify and exchange data through instructions. At present, the interaction between the smart card and the card reader terminal usually interacts with the corresponding smart card through a specific card reader terminal. It can only meet the interaction between a single smart card and a single card reader terminal, and the card reading efficiency is low. Contents of the invention [0004] The invention provides a smart card information readi...
