Electronic chip packages within pouring unbreakable piece cassette seals implanted chip curing the world's unique electronic serial number, only through a dedicated reader, in order to detect the serial number. Seal performance while using laser coding technology provision custom number again, so as to solve the traditional seals easily imitate, security, illegal substitution, difficulty authenticity of the enemy's. After the hand-held detector background with computer networking, enabling table, theft, query integration. Staff can carry hand-held detector to the site by scanning electronic seals or direct input meter box number, Seals number can automatically bring up the user profile information belongs to the measuring instruments, including customer name, address, meter box number, Seals number, chip serial number, meter number, meter reading time. Then enter the measuring instruments current data storage can be imported directly into the background after the computer-generated charge form. Application: widely used in electricity, water, instrumentation and other places need to be sealed to protect, with professional management software and handheld smart seals, seal achieve information management, to ensure the safety seal equipment.
