Of course, in some embodiments, active RFID radio frequency technology may also be used, which can increase signal transmission distance, etc. In the present invention, the rf IC chip or the circuit board rf IC chip electrically connected to the rf antenna circuit are matched with each other, and the following description is omitted.

In this embodiment, lock facing slip 5 is connected with the cooperation of lock body 4 and makes the lock seal device be in the lock state of sealing, and lock facing slip 5 makes the lock seal device be in the unblock state with the separation of lock body 4, because of electrically conductive locking elastic movement piece 3 has the elastic function, contacts with the circuit access end in the lock facing slip 5 or breaks off and realizes that lock seal circuit or other circuits switch on and break off, and other circuits can be radio frequency circuit, or non-radio frequency circuit.

It will be appreciated that the conductive locking resilient movement 3 may itself have a resilient function, such as a spring tab or the like.

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. At present, the antenna is more and more widely applied, the anti-interference requirement is more and more strict, and the design types are diversified.
