The seal face of the new coding standard seal is printed with the fine anti-counterfeiting lines automatically generated by the system (just like a human fingerprint) and 13-digit code, which can be queried by logging in to the \"Seal record access query System\" on the Internet.

The new coding standard seal also has a built-in encrypted electronic chip and seal password, which can be identified by intelligent reading devices or password verification methods, easy to identify, difficult to copy, easy to manage, and the quality is obviously better than the traditional seal.
A chip is an integrated circuit that consists of a large number of transistors. Different chips have different integration scales, up to several hundred million; As small as tens or hundreds of transistors.

The working principle of the chip is to manufacture the circuit on the surface of the semiconductor chip for calculation and processing.

Integrated circuits have two main advantages over discrete transistors: cost and performance.
