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.
