| 摘要 | The invention is directed to systems, methods and computer program products for activating a mobile device application. An exemplary method comprises: storing a threshold change; determining a change in magnetic field using a compass located in a mobile device; comparing the change in magnetic field to the threshold change; determining whether the change in magnetic field is greater than or equal to the threshold change; and in response to determining the change in magnetic field is greater than or equal to the threshold change, activating a mobile device application. | ||

| 主权项 | 1. A method for activating a Near Field Communication (NFC) application on a mobile device, the method comprising: providing for the mobile device having a processor and a compass in communication with the processor; storing, in a memory component, a magnetic field threshold change; determining a change in magnetic field using the compass; comparing, by the processor, the change in magnetic field to the magnetic field threshold change; determining, by the processor, that the change in magnetic field is greater than or equal to the magnetic field threshold change; in response to determining that the change in magnetic field is greater than or equal to the magnetic field threshold change, activating, by the processor, the NFC application for a predetermined period of time; and deactivating, by the processor, the NFC application after the predetermined period of time. | ||
