Abstract

The invention discloses an intelligent card and a working method thereof, a main controller of the intelligent card is electrically connected with the power supply control pin of a security chip, andthe potential of the power supply control pin can be directly detected, so that the main controller can judge whether the intelligent card is in a magnetic field or not according to the real-time potential value of the power supply control pin so as to execute a corresponding function; in this process, the main controller judges whether the intelligent card enters the magnetic field in real time according to the hardware characteristics without judging whether the intelligent card enters the magnetic field through a COS system, so that the detection error or delay of the magnetic signal due tothe limitation and uncertainty of COS detection of the magnetic signal is avoided, and the detection speed and accuracy of the magnetic signal are improved.

Description

technical field [0001] The invention relates to the field of smart card control, in particular to a smart card and its working method. Background technique [0002] Non-magnetic communication technology refers to the technology of short-distance communication through magnetic fields. External card readers send magnetic signals to read the data in the smart card to complete the interaction of business data, or trigger the smart card to perform specific data processing. [0003] The basis of the non-magnetic communication technology is the detection of the magnetic signal. In the prior art, the magnetic signal is detected through the COS (Card Operation System, smart card operating system) in the smart card. After the magnetic signal is detected, the corresponding electrical signal is output. Signal, so that the smart card can perform subsequent operations. Because COS has certain limitations and uncertainties in detecting magnetic signals, it will lead to detection errors or...
