The handheld device has a user identification. The access control server is configured to store a user identification set, connect to the handheld device within a first time interval, determine that the user identification is included in the user identification set, generate a one-time password (OTP) seed set, and transmit the OTP seed set to the handheld device. The terminal recording device connects to the handhold device within a second time interval, and performs a two-way identification certification with the handheld device according to the OTP seed set so that the handheld device performs a data access to the terminal recording device after achieving the two-way identification certification. |
