Method for managing a NFC transaction between a NFC reader and a device including an application and a NFC controller having an ability to communicate in contactless mode which is deactivated. The device includes an indicator uniquely associated with the application. This indicator is set to either a first or a second value. When the NFC controller is awakened by the electromagnetic field generated by the NFC reader, it sends a first message to the application. On receipt of the first message, the application checks the indicator and activates the NFC controller ability to communicate in contactless mode only if the indicator is set to the first value. The NFC transaction is performed through the NFC controller and when the NFC transaction is ended the NFC controller sends a second message to request the application to deactivate the NFC controller ability to communicate in contactless mode.
