Abstract
Embodiments described in the present disclosure disclose a radio frequency discovery method that relates to a first device and a second device. At least two applications are installed on the first device. After a user selects a first application from the at least two applications, a near field communication controller in the first device obtains an RF technology supported by the first application; determines at least one to-be-used RF technology in information indicating the RF technology supported by the first application; then receives a detection command sent by the second device for a first RF technology; and when the to-be-used RF technology includes the first RF technology, sends a response message for the detection command to the second device; or when the to-be-used RF technology does not include the first RF technology, determines not to send a response message for the detection command.
