Thin-film smart card and startup method and communication method based on thin-film smart card

Abstract

The invention discloses a thin-film smart card which is attached to an SIM card and inserted into a mobile phone card slot along with the SIM card. A VCC port, a GND port and a RST port of the thin-film smart card and a VCC port, a GND port and a RST port of the SIM card are jointly connected with a VCC port, a GND port and a RST port of the mobile phone card slot; an IO1 port of the thin-film intelligent card is connected with an IO port of the mobile phone card slot; a CLK1 port of the thin-film intelligent card is connected with a CLK port of the mobile phone card slot; an IO2 port of the thin film intelligent card is connected with an IO port of the SIM card; and a CLK2 port of the thin-film intelligent card is connected with a CLK port of the SIM card. Under the condition that normaluse of a user is not influenced, an independent hardware security unit is provided for a terminal application program on a mobile phone. The invention further provides a startup method and a communication method based on the thin-film intelligent card, and communication between the mobile phone and the SIM and the thin-film intelligent card is effectively achieved.

Description

technical field [0001] The present invention relates to thin film smart cards for mobile phones. Background technique [0002] Smartphones have become a must-have device for everyone.
