You can start here QR Code Generator | Create Your Free QR Codes

 

Here's an outline of the steps you might consider taking:

1. User Interface (Front-End):

• Create a user interface where customers can initiate the document upload process by scanning a QR code.
• Allow users to select or capture images of the documents they want to upload.

2. QR Code Generation:

• Generate QR codes that are unique for each user or transaction. You can use libraries like qrcode in Python or various online QR code generators.

3. Document Upload:

• When users scan the QR code, they should be directed to a web page or app screen where they can upload their verification documents.

4. Document Criteria:

• Define the criteria that the verification document should meet. This could involve file type (PDF, image), size, specific text, watermark, or any other identifying features.

5. Front-End Validation:

• Implement client-side validation to ensure that users are uploading documents that meet the specified criteria before submitting the form.
• Highlight missing information or criteria in the UI to guide users on what's required.

6. Back-End Processing:

• Build a back-end system (using a programming language like Python, Java, PHP, etc.) to handle the uploaded documents and verification process.
• Use libraries for image processing and text extraction (such as OpenCV and Tesseract) to extract relevant information from the documents.

7. Document Verification:

• Analyze the extracted information from the uploaded document to verify if it meets the prescribed criteria.
• You might use regular expressions or specific algorithms to match the required information.

8. Verification Outcome:

• Notify the user about the verification outcome through the UI.
• If the document is verified successfully, store relevant data in your database.
• If the document does not meet the criteria, provide feedback to the user about which part is missing or incorrect.

9. Security and Privacy:

• Implement security measures to protect user data and documents during transmission and storage.
• Ensure compliance with data protection regulations.

10. Monitoring and Improvements:

• Continuously monitor the performance of your document verification system.
• Analyze any rejected documents and reasons for rejection to improve the system's accuracy.

 

Maybe it’s worth outsourcing the task?
