2. Introduction to ID card identification

With the leading artificial intelligence and knowledge graph technology, it automatically recognizes the front and back of the ID card, and extracts the ID card entity information such as name, date of birth, ID number, address, gender, ethnicity, and issuing authority.

3. Call Alibaba Smart Cloud API

Step 1 : Search Alibaba Cloud with your browser, use Alipay or other Ali APP to scan the code and log in with the verification code on your mobile phone.

Step 5 : Check the Python implementation code, and replace the appcode in the code with your own appcode

Step 6 : Check the request parameters, calling the API needs to provide the ID number and ID number in the code Name, no need to upload ID card picture

Step 7 : After running the code, the return value includes whether the real-name authentication is passed, ID number, name, home address and date of birth, etc.
