A method for accessing radio frequency communication with low-frequency magnetic communication, whereby: Step a: a requesting party sends an activation request through a low-frequency channel, namely a low-frequency characteristic code, wherein said low-frequency characteristic code comprises a first random number generated by the requesting party, and the length of said low-frequency characteristic code is shorter than or equal to 2 bytes; Step b (302, 303): a requested party receives the activation request through the low-frequency channel, generates an activation response message and sends the activation response message on a first radio frequency communication address through a radio frequency channel, wherein the activation response message comprises a second random number generated by the requested party and an identity identifier of the requested party; Step c (304, 305): the requesting party receives the activation response message on the first radio frequency communication address through the radio frequency channel and performs the verification, generates a connection request if the verification is passed, and sends the connection request on a second radio frequency communication address through the radio frequency channel, wherein the connection request comprises a third random number; Step d (306, 307): the requested party receives the connection request on the second radio frequency communication address through the radio frequency channel and performs the verification, generates a connection response message if the verification is passed, and sends the connection response message on the second radio frequency communication address through the radio frequency channel; Step e: the requesting party receives the connection response message on the second radio frequency communication address through the radio frequency channel, verifies whether the access is successful, and trades with the requested party on the second radio frequency communication address through the radio frequency channel if the access is successful.
