Document OCR & Integrity Checks

Read every field, verify every security feature. OCR with confidence scoring, MRZ checksum validation, hologram detection, tamper evidence, RFID / NFC chip reading on supported devices — document verification that doesn't stop at the text.

Document OCR and integrity

Supported Documents

From PAN Cards to e-Passports

Pre-trained pipelines for the documents that show up most often in regulated onboarding flows — with the ability to add custom templates for proprietary forms.

Passport (MRZ + Chip)

OCR plus MRZ checksum validation. NFC chip read on supported mobile devices for the full e-passport biometric data block.

PAN Card

Field-level OCR plus structural anomaly flags. Cross-checks against PAN verification API in a chained call.

Aadhaar

OCR with built-in UIDAI-compliant masking of the first 8 digits in the captured image — safe by default.

Driving License

State-format aware. Extracts licence number, class, validity, issuing RTO, address block.

Voter ID (EPIC)

EPIC number, polling-booth details, demographic fields — with anomaly scoring on photo region tampering.

GST Certificate & Bank Statement

Business KYC documents — GSTIN, trade name, registered address; bank statement parsing for income evaluation.

Integrity Checks

Beyond Text Extraction

OCR tells you what the document says. Integrity checks tell you whether the document itself is real. Both matter — especially for cross-border KYC, bank account opening, and high-value loan origination.

Hologram Detection

Optical security-feature analysis. Detects whether the expected hologram pattern is present, oriented correctly, and undistorted.

MRZ Validation

Machine Readable Zone checksum verification per ICAO 9303 — catches forged passports where the visible data has been altered but the MRZ wasn't.

Tamper Evidence

Font anomalies, pixel-level manipulation, suspicious compression artefacts — the signs of digital editing made flaggable for human review.

RFID / NFC Chip Reading

For e-passports and e-NIC cards on capable mobile devices. Reads the chip's signed data block and verifies it against issuing country PKI.

UV / IR Feature Flags

For hardware-assisted flows where customer-facing terminals can illuminate the document under UV or IR — checks the response of security features only visible outside the visible spectrum.

CA-Grade Provenance

eMudhra's CA / PKI heritage is what underwrites the integrity layer — document signatures and chip data are verified against the same trust hierarchies we operate.

Where It's Used

Typical Deployment Patterns

Cross-Border KYC

Airports, embassies, immigration counters — chip-backed passport read plus OCR plus integrity in a single capture event.

Bank Account Opening

OCR feeds form auto-fill; integrity check gates risk decision; chip read used selectively for premium account categories.

Loan Origination

Tamper-evidence flag triggers manual review queue; full OCR feeds underwriting; statement parsing feeds income decisioning.
