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.
