Wireless access method and relevant device and system

摘要

Disclosed are a wireless access method and a relevant device and system. The method comprises: a terminal device reads access point information stored in an external near field communication tag; and the terminal device obtains a piece of target access point information according to the read access point information, and establishes a wireless connection with an access point to which the target access point information is attributed according to the target access point information. In implementing the present invention, the operations of a user manually opening access point search and manually entering a password can be omitted, thereby effectively improving the efficiency of accessing an access point.
