Abstract

The invention provides a subscriber identity module (SIM) card paster and an identity card (IC). A central processing unit (CPU), a memory and a processing program are integrated in the SIM card paster; the SIM card paster is provided with a changeover contact; the changeover contact is used for building connection with a corresponding contact on an SIM card when connection is built between the SIM card paster and the SIM card; and therefore data communication is built between the SIM card paster and the SIM card. The IC card comprises the SIM card paster and a card holder for containing the SIM card paster; the CUP, the memory and the processing program are integrated in the SIM card paster; the connection between the SIM card paster and the corresponding contact of the SIM card is built by the changeover contact of the SIM card paster to ensure that the SIM card and the SIM card paster can carry out data communication; and therefore the function of the SIM card is expanded.

Description

technical field [0001] The invention relates to communication technology, in particular to a SIM card patch and an IC card. Background technique [0002] An ordinary SIM card is a chip card equipped with a microprocessor. There are 5 modules inside it, and each module corresponds to a function: microprocessor CPU, program memory ROM, working memory RAM, data memory EEPROM and serial communication unit. These 5 modules are sealed behind the copper interface of the SIM card in the same way as ordinary IC cards. These 5 modules must be integrated in an integrated circuit, otherwise its security will be threatened. The SIM card can realize a variety of functions, including: storing user-related data, user PIN operation and management, user identity authentication, and encryption algorithms and keys in the SIM card. [0003] In the process of realizing the present invention, the inventor finds that the prior art has at least the following defects: [0004] Once a SIM is made,...
