Biometric Field Validation
- Aviral Mishra (Unlicensed)
In biometric field we have to capture all the attributes mentioned in the array associated with id "bioAttributes".
There is a special scenario in which the age group matches the expression associated with id "ageGroup" present within the id "conditionalBioAttributes". In this scenario we show the attributes associated with id "bioAttributes" present within the id "conditionalBioAttributes" on UI available for capturing. Also the validation will then happen using the expression associated with id "validationExpr" present within the id "conditionalBioAttributes".
Example:
The text file present as an attachment with this article contains New Process Schema.

}Here in the BiometricDetails screen we can see two fields present with id names as "individualBiometrics" and "introducerBiometrics" respectively.
When the age group is :
anything other than INFANT : All the attributes mentioned within "bioAttributes" will have to be captured for "individualBiometrics".
INFANT : Only face will have to be captured for "individualBiometrics" because the id "validationExpr" present within "conditionalBioAttributes" contains only face.
Similarly for "introducerBiometrics" when age group is infant validation will be done based on the validation expression present in id "validationExpr" within "conditionalBioAttributes".
