Abstract

The invention discloses a card reader and a method for executing the card reader, relates to the IC card filed and solves the problem that particular functions cannot be easily added to card readers in the prior art. Service functions are stored in the card reader of the invention. The method for executing the card reader is as below: receiving an operation instruction; analyzing the type of the operation instruction; and calling the service function corresponding to the operation instruction if the operation instruction is the operation instruction for service function calling. The card reader of the invention comprises a storage module for storing the service functions, a receiving module for receiving the operation instruction, an analyzing module for analyzing the type of the operation instruction, and a calling module for calling the service function corresponding to the operation instruction if the operation instruction is the operation instruction for service function calling. The embodiment of the invention is mainly used in the card readers of various IC cards.

Description

technical field [0001] The invention relates to the field of IC cards, in particular to a card reader for reading or interacting information on the IC card and an execution method of the card reader. Background technique [0002] IC cards (Integrated Circuit Cards) can usually be divided into three categories: memory cards, encryption cards and smart cards. They have been widely used in banking, access control, public transportation, computer systems, communications, security and other fields, and the connection between IC cards and people's social life It is also increasingly close, making people's demand and requirements for IC cards higher and higher. [0003] When using the IC card, the user inserts the IC card into the slot of the corresponding card reader, and the card reader reads the information in the IC card or interacts with the IC card, and the read or interacted information sent to the computer device connected to the card reader. [0004] For the smart card i...
