In a specific implementation scenario, a Secure Access Module (SAM) in an identity card reading device needs to perform data interaction with an identity card to be identified through a Micro Controller Unit (MCU). For example, the SAM module needs to acquire the information of the identity card to be recognized through the MCU, and the MCU module sends an information acquisition instruction for acquiring the information of the identity card to be recognized to the identity card to be recognized, so that the identity card to be recognized can feed back at least one type of content information corresponding to the information acquisition instruction. The identity card includes various types of content information, such as name, date of birth, identification card number, fingerprint, photograph, etc. In this implementation scenario, each information acquisition instruction corresponds to one type of content information.

And if the feedback information is not received, not sending the next information reading instruction of the current information reading instruction.
In this implementation scenario, the information reading instruction is used to read 80 bytes of id card information. For example, the first sent information reading instruction is used for reading the 80 bytes of identification card information from the start address of the opened folder. The second sent information reading instruction is used for reading 80 bytes of identity card information by taking the starting address as the 81 th byte, and the like.
For example, the information reading instruction is 80B 0000050, and the feedback information sent by the identification card to be identified in response to the information reading instruction is xx xx xx xx … (80 bytes in total) 9000.

sending the random number reading instruction to the identity card to be identified, so that the identity card to be identified responds to the random number reading instruction and sends an authentication random number to the secure access module;
acquiring an encrypted random number sent by the secure access module, wherein the encrypted random number is acquired after the secure access module encrypts the authentication random number;
and sending the encrypted random number to the identity card to be identified, so that the identity card to be identified completes authentication according to the encrypted random number.
5. The identity card information acquisition method according to claim 1,
and the information interaction with the identification card to be identified is realized through a radio frequency signal.
6. The method for acquiring the information of the identity card according to claim 1, wherein the step of sending the plurality of information acquisition instructions to the identity card to be recognized according to a preset sending sequence comprises:
and judging whether feedback information corresponding to the currently sent information reading instruction is received or not, and if the feedback information corresponding to the currently sent information reading instruction is received, sending the next information reading instruction of the currently sent information reading instruction according to the preset sequence.
7. The identity card information acquisition method according to claim 1,
each information reading instruction is used for reading content information with a preset byte length in the identity card information of the identity card to be identified.
8. An identification card information acquisition apparatus, comprising:
the reading module is used for reading a pre-stored first instruction set, and the first instruction set comprises a plurality of information acquisition instructions;
the sending module is used for sending the plurality of information acquisition instructions to the identity card to be identified according to a preset sending sequence;
the feedback module is used for receiving feedback information sent by the to-be-identified identity card in response to each information reading instruction and sending the feedback information to the security access module, wherein the feedback information comprises at least one type of content information of the to-be-identified identity card;
a receiving module, configured to receive a second instruction sent by the secure access module, where the second instruction includes all the feedback information;
and the information module is used for reading each piece of feedback information in the second instruction and acquiring the identity card information of the identity card to be identified.
9. An identification card information acquisition apparatus, comprising: a processor, a memory and a communication circuit, the processor coupled to the memory and the communication circuit, the memory having stored therein a computer program, the processor executing the computer program to implement the method of any of claims 1-7.
10. A computer-readable storage medium, in which a computer program is stored, which computer program is executable by a processor to implement the method according to any one of claims 1-7.
