The composite anti-counterfeit label has dual anti-counterfeiting functions, so that the anti-counterfeiting reliability is enhanced greatly. Moreover, the making device is simple in structure, and the making method is easy to implement.

An image processing apparatus includes a first communication portion configured to wirelessly communicate with a terminal and a second communication portion configured to carry out near field communication with a terminal. A communication distance between the second communication portion and the terminal is shorter than a communication distance between the first communication portion and the terminal. The image processing apparatus further includes an adjustment portion configured to adjust a communication-established distance over which the first communication portion establishes communication with the terminal so as to match with a specific position at which the second communication portion establishes communication with the terminal.

An information confirmation method and apparatus, a server, and a storage medium are provided by an embodiment of the present invention. The method includes: receiving order information of a first terminal and a second terminal, and obtaining near-field communication information of the first terminal and the second terminal; Generating confirmation information when the near-field communication information of the first terminal and the second terminal satisfies a preset condition; When the received external input status information does not match the acknowledgement information, the alarm information is transmitted. By acquiring the near field communication information of the first terminal and the second terminal, The present relative positions of the two terminals can be judged in real time, and whether the state information is inputted incorrectly is judged by matching the state information inputted by the two terminal users with the confirmation information, and the alarm is given in time, thus realizing the timely confirmation of the information and solving the problem that the information confirmation error can not be reported to the dangerous information in time.

Embodiments of the invention disclose a near field communication (NFC) circuit and a terminal. The NFC circuit comprises a feeding terminal, a signal shielding unit and an NFC control unit, wherein atarget antenna receives a first signal, and the signal shielding unit shields a redundant signal in the first signal, so as to obtain a first NFC signal; during information interaction between the NFCcontrol unit and a control unit in the terminal, if the NFC control unit receives the first NFC signal, a target signal is obtained according to the first NFC signal, the target signal is sent to thecontrol unit so as to enable the control unit to work according to the target signal; and if the NFC control unit receives a control signal sent by the control unit, the NFC control unit obtains a second NFC signal according to the control signal and radiates the second NFC signal through the target antenna. The target antenna is reused, an antenna preset on the terminal is not re-designed or re-arranged, so that the NFC function can be realized on the terminal more easily.

The invention discloses a near field communication triggering method and device, electronic equipment and a storage medium. The method comprises the following steps of when a near field communication tag is sensed, acquiring a first sensing moment when the near field communication tag is sensed, acquiring a write-in moment when the near field communication tag completes data write-in and a preset delay trigger duration, judging whether the difference value between the first sensing moment and the write-in moment is greater than the delay trigger duration or not, and when the difference value between the first sensing moment and the write-in moment is greater than the delay trigger duration, acquiring and executing an instruction in the near field communication tag. By adopting the scheme provided by the invention, the near field communication trigger sensitivity can be reduced, and the near field communication trigger safety can be improved.
