Chip seal is a kind of seal that uses chip technology and cryptography principle to realize identity authentication and anti-counterfeiting.
The principle is that the chip seal integrated with the encryption chip is connected to a specific card reader, and the information stored in the chip is read by the card reader during identity authentication or anti-counterfeiting detection, and the encryption and decryption verification is carried out, so as to achieve the purpose of identity authentication or anti-counterfeiting. The chip seal has the advantages of high security, strong anti-counterfeiting, simple operation, etc., and has been widely used in the fields of government, enterprises and institutions.
Chip stamp is a kind of stamp that realizes electronic authentication by using microchip technology and encryption algorithm. Its principle is to embed the chip inside the seal, through the communication with the card reader, to achieve the seal identity authentication and data encryption and decryption.
The chip seal has the functions of anti-counterfeiting, anti-tampering and anti-copying, and can be widely used in electronic contracts, electronic signatures, finance, public services and other fields.
