Function of security seal

Security seal is a kind of equipment similar as lock implemented by specialized person after goods are loaded in container and correctly close container door. Dividing by different implementing persons, seals can be divided to customs seal, commercial inspection seal and commerce seal. Once locked correctly, it is unable to open unless violent break (cutting) and once broken, seals can’t be used again. Each seal has a unique serial number. As long as container appearance is complete, door correctly closed, seal normally locked, it proves the container is not open during transportation. The inside container situation is supervised by loading person.
Functions of bolt seal
Features of bolt seal: seal body and pole are made of metal; seal inside is clip structure; surface is galvanized. Surface adopts printing to print letters and serial number. Strength F≥900KG. Currently, bolt seal is widely applied to railway, highway, port, aviation, petroleum, chemistry, electricity, post and telecommunications, container, oil tank truck of transportation, packaging bag and all kinds of metering industries.
Functions of plastic seal

Functions of meter seal
1.Realize the digital management of meter reading: read information in non-touched way, automatically tune out water meter customer files, store meter data with super large capacity, automatically generate and derive charged form. Meter readers take handheld reading meter device which can recognize meter seal, automatically tune out user files of this counter through recognizing electronic seal, and then input the data of measuring instrument and directly lead in computer software and generate charging table after storage.
2.The guardian angel and safety lock of measuring instrument: prevent false making of seal, forbid the occurrence of water, electricity and gas stolen. Common seals depend on the clamp mark to judge the false and truth of seal, which is very easy to counterfeit. While each electronic seal has one unique identification code which is programmed at the time of making semi-conductor chip and is realized by laser printing. It is nonrepetitive around the world. The only code of chip can be readable through wireless non-contact way, and compare with database to judge the false and truth of seals. The production cost of IC card water meter electronic seal is comparatively low, but copy cost is very expensive and with much difficulty, which essentially shut the door upon illegal persons. The prevention of copy can bring great economic benefit to public enterprise companies.
