Abstract: A method includes determining, by an NFCC of a first NFC device, whether the NFCC is responsible for determining a maximum length value of data packets transmitted in subsequent communication. The method further includes sending a first request comprising a first length value to a second NFC device when the NFCC is responsible for determining the maximum length value. The first request further includes a first DID. The method further includes receiving a first response that is returned by the second NFC device for the first request and that comprises a second DID. The method further includes using the first length value as the maximum length value of the data packets transmitted in the subsequent communication when the first DID is the same as the second DID.

Abstract: A method, an apparatus, and a system are provided for adjusting a data packet length in near field communication NFC. The method includes: determining, by an NFCC of a first NFC device, whether the NFCC is responsible for determining a maximum length value of data packets transmitted in subsequent communication; if yes, sending a first request comprising a first length value to a second NFC device, the first request further includes a first DID; receiving a first response that is returned by the second NFC device for the first request and that comprises a second DID; and when the first DID is the same as the second DID, using the first length value as the maximum length value of the data packets transmitted in the subsequent communication.

Abstract: Embodiments of the present invention provide a routing method, a near field communication controller, a device host, and a terminal, where the method is used in a first terminal, the first terminal includes a device host DH, a near field communication controller NFCC, and at least one near field communication execution environment NFCEE. The method includes receiving, by the NFCC, a data frame sent by a second terminal and determining, by the NFCC, whether a default-NFCEE-based routing manner is used to search for a matched routing entry for the data frame. The method also includes if yes, determining, by the NFCC, a target NFCEE according to the default-NFCEE-based routing manner, so that the NFCC routes the data frame to the target NFCEE.

Abstract: A card binding method is applied to a terminal. The card binding method includes displaying a first screen, where the first screen displays bank cards associated with an account number with which a digital wallet APP is currently logged in to; determining a to-be-verified bank card and at least one to-be-bound bank card from the bank cards; displaying a second screen, where the second screen is used to prompt a user to enter verification information of the to-be-verified bank card; and sending the verification information to a server to request the server to deliver a card application and personalization data corresponding to each to-be-bound bank card to the terminal after verification performed on the verification information succeeds, to complete binding of the at least one to-be-bound bank card.

Abstract: A capability enabling method and apparatus. A secure element (SE) establishes, with a trusted execution environment (TEE), a session for communication. The SE sends, to the TEE, an obtaining instruction to obtain a security certificate of the TEE. After receiving the obtaining instruction, the TEE generates the security certificate based on attribute information of the TEE, and sends the generated security certificate to the SE. After the SE receives the security certificate, the SE determines, based on the security certificate and a preset security policy, that the TEE is in a secure state. After the SE determines that the TEE is in the secure state, the SE enables a first capability for a third-party service in the SE based on a second capability of the TEE.

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.
