Abstract

The invention discloses a smart card and a working method of the smart card. The smart card comprises a card body and an auxiliary module connected with the card body, wherein the auxiliary module is used for receiving an operational order and judges whether the operational order is given to the auxiliary module or the card body for processing; if the operational order is given to the card body for processing, the auxiliary module sends the operational order to the card body; if the operational order is given to the auxiliary module for processing, the auxiliary module processes the operational order; the auxiliary module sends a processed result outside after the processing by the auxiliary module or the card body is completed, and the card body is used for receiving the operational order transmitted by the auxiliary module, processes the operational order, and transmits the processed result to the auxiliary module.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a smart card and a working method of the smart card. Background technique [0002] Smart cards are widely used in various devices, such as secure digital card SD, TF card (TransFLash, also known as: Micro SD), etc., widely used in digital cameras, audio players and other equipment, subscriber identification module (SIM card) is widely used in the phone.
