Emulated Card Selection Method and Mobile Device

An emulated card selection method, implemented by a mobile device comprising a near field communication (NFC) function, a first emulated card, and a second emulated card, wherein the emulated card selection method comprises:

• detecting whether a front side of the mobile device is close to an NFC card reader when detecting an NFC radio frequency field;
• selecting the first emulated card when the front side of the mobile device is close to the NFC card reader;
• selecting the second emulated card when the front side of the mobile device is not close to the NFC card reader;
• and
• performing NFC interaction with the NFC card reader based on the first emulated card or the second emulated card.

A mobile device, comprising:

• a first emulated card;
• a second emulated card;
• a near field communication (NFC) apparatus coupled to the first emulated card and the second emulated card and configured to:
• detect an NFC radio frequency field of an NFC card reader;
• and
• perform NFC interaction with the NFC card reader based on the first emulated card or the second emulated card;
• a memory coupled to the NFC apparatus;
• and
• a processor coupled to the memory and the NFC apparatus and configured to:
• detect whether a front side of the mobile device is close to the NFC card reader when the NFC apparatus detects the NFC radio frequency field of the NFC card reader;
• select the first emulated card when the front side of the mobile device is close to the NFC card reader;
• and
• select the second emulated card when the front side of the mobile device is not close to the NFC card reader.

A computer program product comprising instructions for storage on a non-transitory computer-readable medium that, when executed by a processor, cause a mobile device to:

• detect whether a front side of the mobile device is close to a near field communication (NFC) card reader when detecting an NFC radio frequency field;
• select a first emulated card of the mobile device when the front side of the mobile device is close to the NFC card reader;
• select a second emulated card of the mobile device when the front side of the mobile device is not close to the NFC card reader;
• and
• perform NFC interaction with the NFC card reader based on the first emulated card or the second emulated card.
