The detection chip 12 has an APDU (Application Protocol Data Unit ) instruction list and a detection program built therein for detecting the application chip 11.
In this embodiment, the power supply circuit 13 includes a charging circuit 131 and a rechargeable battery 132, the charging circuit 131 is electrically connected to the rechargeable battery 132, and the rechargeable battery 132 is electrically connected to the control switch 15.

As shown in fig. 3, when the self-checking method of the smart IC card of the present invention performs the checking, step S1 is executed first, and a preset ADPU command is sent to the application chip 11 and the checked data returned by the application chip 11 is obtained. When transmitting data to the application chip 11, data is generally transmitted in the form of a message, and therefore, when communicating with the application chip 11, data interaction is performed by an APDU command. The preset ADPU instruction is used to simulate an APDU instruction that needs to be transmitted when the smart IC card 1 is actually used. The application chip 11 returns detected data after acquiring the ADPU instruction, where the detected data needs to be set according to service logic of the application chip 11 and content expected to be checked, and a set principle is that the detection chip 12 detects that the successful application chip 11 cannot be abnormal in an actual use process. For example, the detected data returned by an application chip includes reset answer (ATR, answer To Request) information, application selection data, acquisition processing option (GPO, get Processing Options) command data, read record data, offline data authentication information, and generation of application ciphertext (GAC, generate Application Cryptogram) command information, etc.
After the detected data is obtained, step S2 is executed, and the detected data is detected according to a preset rule, so as to obtain detection result information.

When transmitting data to the application chip 11, data is generally transmitted in the form of a message, and therefore, when communicating with the application chip 11, data interaction is performed by an APDU command. The preset ADPU command is used to simulate APDU commands that need to be transmitted when the smart IC card is actually used. The application chip 11 returns detected data after acquiring the ADPU instruction, where the detected data needs to be set according to service logic of the application chip 11 and content expected to be checked, and a set principle is that the detection chip 12 detects that the successful application chip 11 cannot be abnormal in an actual use process.
The detection module 22 is configured to detect the detected data according to a preset rule, and obtain detection result information. Each item of the acquired detected data can be set with a rule corresponding to detection, for example, the acquired detected data is compared with each item of data stored in the detection chip 12, and whether the corresponding data is consistent is verified; or verifying whether the acquired detected data accords with a preset specification, wherein the preset specification can be a specification commonly used by the existing intelligent IC card; or to verify whether the transmitted instruction can get normal feedback, etc. normally.
