Abstract: A method and an apparatus for invoking a radio frequency card function are provided. The method includes: monitoring a feature input event, and obtaining feature information of a user from the feature input event obtained through monitoring; determining, based on a mapping relationship between the feature information and a radio frequency card type, a target radio frequency card type corresponding to the feature information of the user; and invoking a radio frequency card function corresponding to the target radio frequency card type. According to the method, different radio frequency card types may be distinguished based on the feature information of the user, so that the radio frequency card function corresponding to the target radio frequency card type corresponding to the feature information of the user can be invoked based on the feature information of the user. This further improves a card swiping success rate and improves user experience.

Abstract: An electronic transaction method and a terminal are provided for automatically selecting, based on type information of an electronic device, a transaction account corresponding to the type information of the electronic device, and transacting with the electronic device by using the transaction account. In this way, user operation is simplified and user experience is improved. The method includes: establishing a near field communication connection to an electronic device, a request message sent by the electronic device through near field communication, where the request message includes type information of the electronic device; and obtaining the type information of the electronic device from the request message, and determining, from at least two different types of transaction account information based on the type information of the electronic device, a transaction account corresponding to the type information.

Abstract: The present invention discloses a payment authentication method and apparatus for a mobile terminal, and a mobile terminal. The method includes: obtaining, by a mobile terminal, first biometric feature information entered by a user; comparing, by the mobile terminal, the first biometric feature information with second biometric feature information, where the second biometric feature information is prestored biometric feature information used for user identity authentication; comparing, by the mobile terminal, the first biometric feature information with third biometric feature information if the first biometric feature information matches the second biometric feature information, where the third biometric feature information is prestored biometric feature information used for payment authentication; and determining, by the mobile terminal, that payment authentication is complete when the first biometric feature information matches the third biometric feature information.
