When the conventional IC card meter is used for detecting a read-write card, the time sequence and data can be analyzed only by aiming at a naked circuit board, and no scheme can be realized for the whole meter. The probability of analyzing the entire table is much greater than the probability of analyzing bare circuits. The reason is mainly that a new type of smart card needs to be developed to match with the card-hung table, and the card-hung table involved in the new type of smart card may be the card-hung table of other manufacturers. Therefore, the IC card table can not be read and written in a whole table and the analysis processing of data can not be realized without disassembling the table.
