The utility model belongs to the technical field of identity card information acquisition, and relates to an identity card information acquisition circuit and an identity card information reading machine, and the identity card information acquisition circuit comprises a main control module, a power supply module, an RFID module, a filtering module, a wireless transmission module, a serial port and an upper computer. The power module is connected with an input power; the wireless transmission module is used for activating a radio frequency circuit in an identity card, receiving an identity ciphertext signal modulated by the radio frequency circuit and transmitting the identity ciphertext signal to the RFID module through the filtering module, the RFID module is used for demodulating the identity ciphertext signal into identity information ciphertext data and then sending the identity information ciphertext data to the main control module, and the main control module is used for temporarily storing the identity
