Problems solved by technology

[0004] In view of the actual needs of analyzing and locating the abnormal interaction between the existing non-contact smart card and the card reader, the present invention proposes a communication protocol analysis device for the non-contact smart card, which can capture the non-contact smart card without affecting the original communication state. All the interactive signals between the smart card and the card reader are demodulated and decoded according to the contactless smart card communication protocol to decode the actual interactive data and analyze the data, which can effectively improve the efficiency and effectiveness of contactless smart card or card reader problem location

Abstract

The invention relates to the field of test and verification. Aiming at the need to capture and analyze all the data in the interaction process under abnormal interaction in communication between a contactless smart card and a contactless card reader, a contactless smart card communication protocol analysis device is presented. The contactless smart card communication protocol analysis device includes a low-coupling high-frequency antenna, a card reader data analysis module, a card data analysis module, a card reader sent data baud rate monitoring module, an embedded processor and a PC displaymodule. By using the device, interaction data can be captured in the process of interaction between a contactless smart card and a contactless card reader without affecting the communication state, and thus, support is provided for the rapid and efficient analysis of abnormal interaction.

Description

technical field [0001] The invention relates to the field of test verification and provides a communication protocol analysis device for a contactless smart card. Background technique [0002] With the popularization of contactless smart card applications, the number of cards issued continues to increase, and the application scenarios of smart cards are becoming more and more abundant. Card readers experience various interaction anomalies. [0003] In order to quickly locate and repair the problem of abnormal interaction, there is an urgent need for a method that does not affect the original communication state and can capture all the interaction signals between the contactless smart card and the card reader, and demodulate and decode the actual interaction data according to the contactless communication protocol. The device for data analysis helps contactless smart card or card reader designers quickly find the cause of abnormal interaction. Contents of the invention ...
