Qr code anti-counterfeit seals:
The traditional seal with lead, is easy to be imitated, and easy to open power theft molecules. New intelligent metering seal with qr code identification model, has a large capacity of information, can be encrypted, error correction, code of Chinese characters, can be encoded graphics/sound, etc. In addition, the application on the seal of electric energy metering device, can skillfully used together with the traditional lead seal, the formation of a new type of security seal based on qr code.
This new type of electric energy metering device security seal the disposable use, not easy to damage, and because the qr code in the production process to ensure its uniqueness, once opened, therefore, will not be able to recover. The possibility of power theft molecules copied this seal is almost zero.
Based on radio frequency identification (RFID) electronic seal:
RFID is a non-contact automatic identification technology, it through radio frequency signal automatically identify target and get the relevant data. Identify work without manual intervention, can work in all kinds of bad environment. Electronic tags can be used in both anti-counterfeit seals, have the effect of the seal, and convenient management of intelligent watt-hour meter. Is now in parts of small batch trial. But the price factor, as well as scientific and rational application mode is the two key factors affecting its wide application.
