Verify a customer’s Nigerian Permanent Voter’s Card (PVC) by uploading a photo — no manual voter ID entry required. OCR extraction plus a required face match against a selfie — no liveness check (no video, no blink/motion challenge).

This is a two-sided document — supply both document_front and document_back for the most complete extraction.

selfie_image is required — the face extracted from the document is compared against it. This is a still-image comparison (not liveness).

Extra Fields — extra_fields carries whatever else the PVC printed beyond the fields listed above (occupation, state, LGA, ward, polling unit code, registration date, batch/serial numbers). Only fields actually present on the card are included.

Face Match Notes — if the comparison service itself fails, attempted reflects whether a comparison was actually run and verified comes back null with a reason field explaining why — this is different from verified: false, which means the comparison ran and the faces didn’t match. A face-match problem never blocks the underlying document data — the rest of data is still returned.
