Understanding the minConfidence Parameter
The minConfidence is something that changes for each end-user, as it depends on the scanning environment. Changing the minConfidence value changes the precision and recall of the whole scanning script.

Examples of Different Industries requiring Different Confidence Values
| Info |
|---|
Some end-users might require a high confidence to avoid wrong readings, whereas others might wish to lower the confidence to gain more speed. |
Speed over Accuracy
One example of an industry that would require speed over accuracy is the Event Management Industry.
...
While accuracy is still a priority, speed is crucial to prevent long queues and ensure a smooth entry process, so there can be room for tolerating a slight margin of error. While the decision to lower minConfidence should be made carefully, considering the potential trade-offs, trying to achieve a much higher accuracy on the first scan could result in delays and longer queues and waiting times.
Accuracy over Speed
One example of an industry where the opposite would be the case is the Banking and Finance Industry.
...
It would therefore be more beneficial to adjust the minConfidence to prioritise accuracy over speed. Even if it takes a bit longer to process a new account, the trade-off for ensuring client safety and lowering the potential cost and risk associated with incorrect identification would be worth it.

PLEASE NOTE:
Some configs, such as the universalIdConfig, use a differently named parameter called minConfidenceField.
The minConfidenceField determines the minimum confidence a field text needs to reach in order to be taken into account.
If the scanned field confidence is lower than the set minConfidenceField but the scanOption is not set to mandatory, a result will be returned without the field.
This is a confidence value on a field basis for multi-field capabilities like ID.
