Configure OCR confidence threshold
Understand when low OCR confidence should trigger a stricter receipt-review posture.
OCR confidence is the system's estimate of how reliably it read the receipt image. If the threshold is set too low, poor-quality scans may pass into the challenge more easily. If it is set unrealistically high, normal store receipts may be rejected too aggressively.
What this setting influences
OCR confidence does not replace the acceptance policy. Instead, it affects how much trust you place in the data before the policy is evaluated or escalated.
In practice, lower confidence usually means more edge cases, more manual checking, or more participant frustration when receipt quality varies.
When to be stricter
Use a stricter confidence posture when:
- the reward value is high
- fraud risk is a serious concern
- receipts often come from many similar-looking store formats
- operators are available to review edge cases manually
When to be more permissive
A more permissive posture can make sense when:
- receipt quality is highly variable in the field
- the reward is low-risk
- you prefer fewer false rejections and can tolerate more manual review later
Validation messages to watch
| Validation message | Meaning |
|---|---|
Receipt game '{{touchpoint_name}}' has invalid confidence threshold ({{confidence_threshold}}) | The configured value is outside the supported range. |
Receipt game '{{touchpoint_name}}' has low confidence threshold ({{confidence_threshold}}) | The challenge may accept OCR results that are too uncertain for the campaign goal. |
Pair confidence decisions with photo guidance
The best confidence threshold still depends on the participant image. The product already encourages users to submit a photo that is clear, sharp, centered on the receipt, and shows the merchant plus amount. If OCR quality becomes a recurring issue, improve the upload guidance before you only tighten policy.
