Why Was Data Extracted Incorrectly?

Understanding AI extraction accuracy and how to correct mistakes

1 min read

NeatPass uses an on-device AI model that runs entirely on your iPhone. This ensures your tickets never leave your phone for complete privacy, but on-device models can sometimes make mistakes compared to cloud-based alternatives.

Why This Happens

  • On-device processing: The model is optimized to run locally, trading some accuracy for privacy
  • Unusual formats: Non-standard ticket layouts can confuse the AI
  • Poor quality: Blurry images or compressed PDFs make extraction harder
  • Multiple languages: While multilingual extraction works, some languages have lower accuracy

How to Fix It

1

Review before saving

Always check the extracted fields before adding to Wallet. Catch mistakes early.

2

Edit any field

Tap edit to manually correct any mistakes. All fields are fully editable.

3

Try again

Sometimes re-processing produces better results. Delete and re-import the ticket.

4

Use a clearer source

Higher quality PDFs and images improve accuracy significantly.
