Problems solved by technology

When dealing with system problems related to IC cards, engineers found that in order to analyze and solve problems, it is necessary to know whether the communication data between the IC and the device that reads and writes the IC card is correct or not, but this depends on the return data of the read-write device alone. Insufficient, and engineers lack special equipment to obtain the communication data between the two, professional equipment for IC card development can do it, but the cost is extremely expensive, and it is not feasible to use widely

Embodiment Construction

[0015] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0016] see figure 1 As shown, it is a simplified structural diagram of the IC card communication monitoring device of the present invention, which includes three parts: an IC card interface module 21 , a data processing module 22 and a card reader interface module 23 .

[0017] The IC card interface module 21 is mainly composed of an IC card holder and a SIM card holder. Insert the IC card 1 that needs to be monitored into the deck of the IC card interface module 21 when in use, so that the IC card 1 can accept the data sent by the data processing module 22 or send the data returned by the IC card 1 to the data processing module twenty two.

[0018] The data processing module 22 is mainly composed of a data processing chip RS232 interface chip MAX202 and a connector socket DB9M, which is the core module ...

Abstract

The invention is an IC card monitor apparatus that comprises a card-reader interface module, an IC card interface module as well as a data signal process module, wherein, the IC card interface moduleis connected with an IC card; the card-reader interface module is linked to an IC card read-writing device; the data signal process module is respectively connected with the card-reader interface module as well as the IC card interface module; meanwhile, the invention can perform signal process and data output for the data signals in the communication between the IC card and the card-reader, so asto establish a 'bridge' between the card-reader and the IC card; the bridge is not only a data channel of normal communication between both parties, but also has the function of data interception before being delivered to a PC for further process and analysis.

Description

technical field [0001] The invention relates to a data collection device, in particular to a device for monitoring and analyzing communication data of an IC card. Background technique [0002] At present, IC cards are widely used as electronic bills and electronic ID cards in more and more occasions, such as banking, taxation, refueling, social security, public transportation, campus card and other systems, IC cards are used in these systems It effectively protects the security of information and improves the efficiency of system work. However, in the application of various industries, the scale, coverage, technical level and compatibility of the system are different, which leads to various system problems including IC card identification. When dealing with system problems related to IC cards, engineers found that in order to analyze and solve problems, it is necessary to know whether the communication data between the IC and the device that reads and writes the IC card is ...
