Fingerprint capture in Survey solutions

Dear Team,

So here is my question. I have beneficiaries that I want to enrol for a program and would want to capture lots of their details. Further, I want to ensure there is no duplication and to achieve this, I intend to capture their fingerprints. For this purpose, the fingerprints will be captured as image. How can I achieve this in SS if I have the sdk of the biometric device?

Two, Is it also possible to preload previous data using the barcode feature if initially I provided them with the barcode?

I just want to ensure there is no duplication of records and also use biometrics.
