Embodiment 1

[0032] The embodiment of the present invention provides a method for making a smart card, such as figure 1 As shown, the method includes:

[0033] 101. Read the data on the non-volatile memory of the mother card, where the mother card is a smart card made through the preliminary process;

[0034] First, the host computer executes the initialization program and the pre-personalization program in turn to make a smart card, which is called the master card, and the card to be produced is called the target card. Making a mother card is different from ordinary smart cards. When making a mother card, the COS design function of the mother card realizes the data interface of the non-volatile memory area for the host computer to read the data in the non-volatile memory area of ​​the mother card. Here, the interface is designed for the mother card in order to export the data in the non-volatile memory area of ​​the mother card. For the target card, from the perspective of security, this...

Embodiment 2

[0049] The embodiment of the present invention provides a device for making a smart card, such as figure 2 As shown, the device includes a reading module 201 , a combining module 202 and a writing module 203 .

[0050]Wherein, the reading module 201 is used to read the data on the non-volatile memory of the mother card, and the said mother card is a smart card made by the preliminary process; the merging module 202 is used to store the data read by the reading module , and merge the data and the initialization program into a preliminary file; the writing module 203 is used to write the preliminary file generated by the merging module into the target card through a data address write operation.

[0051] Among them, the reading module 201 reads the data on the non-volatile memory of the mother card through the interface set in the mother card, including the sending unit 205, the first reading unit 206, the second reading unit 207 and the third reading unit. Unit 208. Wherein,...

Embodiment 3

[0059] Embodiments of the present invention provide a system for making smart cards, such as Figure 4 As shown, the system includes a device 401 for making smart cards, a master card 402 and a target card 403 .

[0060] Wherein, the device 401 for making a smart card is used to issue instructions to the mother card 402, read the data on the non-volatile memory of the mother card, store the data read from the mother card 402, and combine the data and the initialization program into Preliminary file, the preliminary file is written into the target card 403 through the data address write operation; the mother card 402 is a smart card made by the preliminary process, which is used to receive the instructions issued by the device 401 for making the smart card, and according to the smart card made The first command issued by the device 401 of the master card sends the distribution of valid data on the non-volatile memory of the master card to the device 401 for making the smart car...

Abstract

The embodiment of the invention discloses a method for manufacturing an intelligent card, a device, a master card and a system, which belong to the field of intelligent cards and can improve the preliminary speed of cards in the production of intelligent cards. The technical proposal provided by the embodiment of the invention is as follows: the method for manufacturing the intelligent card comprises the following steps of: reading data of a nonvolatile storage of the master card, wherein the master card is an intelligent card manufactured by a preliminary procedure; storing read data and combining the read data and an initialization program into a preliminary file; and writing the preliminary file into a target card by the write operation of data addresses. The technical proposal provided by the embodiment of the invention is applicable to an intelligent card production system.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a method, a device, a mother card and a system for making a smart card. Background technique [0002] The smart card is composed of hardware and software. The hardware system mainly includes the central processing unit CPU, non-volatile memory NVM, random access memory (random access memory, RAM), read-only memory (readonly memory, ROM) and other parts. The software system includes a chip operating system (Chip Operation System, COS), applications running on the COS, and files for storage. [0003] The pre-preliminary process is an important process in the production of smart cards. Its purpose is to complete the writing of the software system on the target card, thereby completing the production of smart cards. Currently in production, the host computer executes the initialization program and the pre-personalization program in sequence to complete the initial pre-preparation of the s...
