Patent ID: 8615083

Claim:
A method for accessing to radio frequency communication with low-frequency magnetic communication, comprising: Step a: a requesting party, through a low-frequency channel, sends an activation request which is a low-frequency characteristic code, wherein said low-frequency characteristic code comprises a first random number generated by the requesting party, wherein the length of said low-frequency characteristic code is shorter than or equal to 2 bytes, and the length of said first random number is 1 byte; Step b: 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 the 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: 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: 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; and Step e: the requesting party receives the connection response message on the second radio frequency communication address through the radio frequency channel, verifies whether a connection is successful, and trades with the requested party on the second radio frequency communication address through the radio frequency channel if the connection is successful.
