Cross-platform IC card reader-writer operating system and operating method

Abstract

The invention provides a cross-platform IC card reader-writer operating system and an operating method. The system comprises an upper-layer application, a network service assembly in communication connection with the upper-layer application and an IC card reader-writer in communication connection with the network service assembly. The network service component comprises a transceiving unit and a conversion calling unit in communication connection with the transceiving unit; the upper-layer application is used for generating and sending a first description character string used for calling the function and receiving a second description character string used for feeding back a function calling result from the transceiving unit according to the function to be called and a preset description protocol; the transceiving unit is used for receiving the first description character string from the upper-layer application and sending the second description character string to the upper-layer application; and the conversion calling unit is used for analyzing the first description character string, calling a function corresponding to the IC card reader-writer according to an analysis result and generating a second description character string according to a description protocol and a function calling result. According to the invention, the secondary development difficulty of the IC card reader-writer can be reduced.

Description

technical field [0001] The invention relates to the technical field of IC card reader-writers, in particular to a cross-platform IC reader-writer operating system and an operation method. Background technique [0002] Integrated Circuit Card (IC card), also known as Smart card, Intelligent card, Microcircuit card or microchip card. It is made into a card form by embedding a microelectronic chip in a card base conforming to the ISO 7816 standard. [0003] Due to its inherent advantages of information security, portability, and relatively complete standardization, integrated circuit cards are being used more and more in fields such as identity authentication, banking, telecommunications, public transportation, and parking lot management, such as second-generation ID cards, Electronic wallets in banks, mobile phone SIM cards in telecom, bus and subway cards in public transportation, and parking cards used to collect parking fees all play an important role in people's daily lif...

Problems solved by technology

[0005] In the existing technology, the manufacturer of the IC reader-writer will provide the produced equipment to the grass-roots service provider, and the grass-roots service provider will provide the IC reader-writer to the customer after secondary development according to the customer's needs. In order to make the IC Readers can be developed and used on different platforms and operating systems. Manufacturers need to develop different interface libraries on different platforms and operating systems, and provide calling methods suitable for various development languages. Basic services Manufacturers can do secondary development based on the interface library, and when it comes to the application of browser and server architecture (Browser / Server Architecture, BS architecture), manufacturers also need to develop controls under different browsers for use by grassroots service providers. The traditional development method has the following disadvantages: firstly, the manufacturer needs to provide different interface libraries or controls for different processors, operating systems and browsers, and the manufacturer's development, testing and maintenance workload is huge; secondly, different The function interface defined by the development language cannot be kept uniform, and the calling methods are also different, which brings great inconvenience to both the manufacturer and the grass-roots service provider. The learning and development costs of the grass-roots service provider are high, and customers use it under different platforms. It is also impossible to maintain a consistent experience, which is not conducive to the improvement of user experience
