Abstract: An emulated card selection method is implemented on a mobile device having a near field communication (NEC) NFC function. A first emulated card and a second emulated card are configured on the mobile device, When detecting an NFC radio frequency field, the mobile device detects whether there is fingerprint input. The mobile device selects the first emulated card if there is the fingerprint input. The mobile device selects the second emulated card if there is no fingerprint input. The mobile device performs NEC interaction with the NFC card reader based on the selected first emulated card or second emulated card. The mobile device can automatically select an emulated card in different emulated cards based on a card swiping status when a user uses an NEC emulated card.

A technical solution provided in the embodiments of this application is as follows: obtaining a login status of a target account of a target application; if the login status of the target account is non-logged-in, obtaining a first notification message corresponding to the target account of the target application; and clearing the first notification message.

Abstract: A terminal installs, according to a type of an HCE application, the HCE application in a terminal environment corresponding to the type of the HCE application. The terminal parses a first identifier of the HCE application and a second identifier included in the HCE application, where the first identifier identifies the HCE application in the terminal, and the second identifier identifies a message flow between a card reading device and the HCE application. The terminal registers routing information of the HCE application with the TEE, where the routing information includes the first identifier, the second identifier, and the terminal environment in which the HCE application is installed. An HCE application with two different security levels, a TEE and an REE, is supported on a terminal.

Abstract: This application relates to electronic hardware, and in particular, to a handheld terminal that performs a transaction based on NFC. A first terminal and a second terminal each support multiple transaction manners, negotiate a to-be-used transaction manner by using an NFC connection, and automatically invoke a payment client to initiate a transaction request to a transaction server. The first terminal and the second terminal further sort and screen the multiple transaction manners before negotiation.

Abstract: A bank card adding method includes receiving, by a first terminal, a bank card adding request, establishing, by the first terminal, a peer-to-peer wireless communication connection to a second terminal, sending, by the first terminal, a request for obtaining bank card data to the second terminal, receiving, by the first terminal, the bank card data sent by the second terminal, obtaining, by the first terminal, bank card account information based on the bank card data, and sending, by the first terminal, a card issuing request to a first server to add a bank card to the first terminal, where the card issuing request includes the bank card account information.

Abstract: A payment verification method and apparatus are disclosed. The method includes: if a payment terminal detects that there is valid verification information in a secure storage of the payment terminal, changing, by the payment terminal, a cardholder verification method (CVM) supported by a currently used payment card to “no CVM required”, where the payment card is a preset card or a card selected by a user, and the secure storage of the payment terminal is a trusted storage area in a trusted execution environment (TEE) or a secure storage area in a rich execution environment (REE); and notifying, by the payment terminal, the settlement terminal that the CVM supported by the payment card is “no CVM required”, so that the settlement terminal performs verification on the user and completes a transaction according to “no CVM required”.
