In this embodiment, 2 bits are taken each time from the end of the data, and then the data are arranged in sequence, assuming that the original data is 1A5221B4, and 2 bits are taken each time from the end, namely B4, 21, 52, 1A, and then the data are arranged in sequence, so that the adjusted data is B421521A.

The conversion of the system can be adjusted according to the actual application requirement, for example, the 16 system is converted into the 8 system, and the like, but is not limited thereto.
S1353, performing bit complementing processing on the first data information after the system conversion to generate second card number information with a specified length;

The position of the complement bits may also be adjusted, for example, at the end, beginning, or designated byte location of the data.
As shown in fig. 6, S1360 obtains all the first data information stored in the target sector, and defines all the first data information sets as the second data information, which specifically includes:

The calculation rule can be adjusted according to the actual application requirement, and is not limited herein.
By means of calculating the verification information by the first card number information of the IC card, the diversity of the verification rules of the IC card is increased, the safety of the IC card can be further increased, and the possibility of being cracked is reduced.
