Abstract

The invention discloses a subscriber identity module (SIM) card with a non-contact communication function and a working method thereof. The SIM card comprises an SIM card chip, a radio frequency (RF) chip and an IC card chip, wherein the IC card chip is provided with an externally connected international organization for standardization (ISO) 7816 interface connected to the baseband chip of a mobile terminal and is respectively connected to the SIM card chip and the RF chip; the RF chip is used for receiving a first RF signal, performing the analog-to-digital conversion on the first RF signal in order to acquire a first application protocol data unit (APDU) instruction, rousing the IC card chip, and performing the analog-to-digital conversion on a performing response to the first APDU instruction fed back from the IC card chip so as to acquire a second APDU instruction and sending the second APDU instruction; and the IC card chip is used for receiving the first APDU instruction, returning the obtained performing response to the first APDU instruction to the RF chip, transmitting the second APDU instruction sent from the mobile terminal to the SIM card chip, and transmitting the performing response to the second APDU instruction fed back from the SIM card to the mobile terminal.
