Abstract: Embodiments of the present invention relate to a trusted application access control method and a terminal. The method includes: receiving, by a terminal in a TEE, a request for accessing a target trusted application (TA) that is sent by a client application (CA); determining, by the terminal, a service level of the CA in a trusted execution environment (TEE) based on the request for accessing the target TA; and providing, by the terminal in the TEE by using the target TA, a service corresponding to the service level for the CA. In this way, the target TA provides different levels of services for the CA, and determines, in the TEE, the service level corresponding to the CA, thereby enhancing constraint and limitation of accessing the target TA by the CA, and improving security of accessing the target TA by the CA.

Abstract: The present disclosure describes, among others, an example method for registering a mobile POS. One method includes receiving, by a mobile terminal, a mobile POS registration instruction. The mobile terminal then obtains first registration data of a user, where the first registration data includes electronic identity information, security environment information of the mobile terminal, and POS associated information, where the POS associated information includes bank card information. The mobile terminal can then send a mobile POS registration request to a POS center, where the request includes the first registration data or second registration data obtained after the first registration data is processed, where the first registration data or the second registration data is used by the POS center to determine whether the user and the mobile terminal meet a mobile POS registration condition. The mobile terminal then receives a registration response result returned by the POS center.

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.
