Zusammenfassung:	The present invention provides a data exchange method for a universal SIM (USIM) card, suitable for an electronic device, including: in response to determining that the USIM card is inserted into the electronic device, installing a SIM toolkit (STK) menu in the USIM card, wherein the USIM card includes a card manager, and the card manager manages an applet corresponding to a card; in response to determining that a PIN code corresponding to the card is received in the STK menu, calling the applet to verify the PIN code; in response to the applet determining that the PIN code is verified, the applet sends a first request through the STK menu to a remote device, wherein the remote device establishes an elliptic curve Diffie-Hellman (ECDH) secure channel with the applet in response to the first request; using the ECDH secure channel to perform data exchange related to the card with the remote device.
