What is the signal code?

Messenger code is a two-dimensional code used to assist identity authentication. The generation of mnemonic code is based on personal information and encryption algorithm, which is unique and unchangeable, and can effectively protect personal privacy and data security. When handling bank business, social security card, driver's license and other documents, mnemonic code is a two-dimensional code used to assist identity authentication. People need to provide mnemonic code for identity authentication to ensure the accuracy of personal information and business processing.
