# Decision payload (excerpted):
{ "nfc_verification": { "passive_authentication": "Approved" },
"face": { "matched_against": "chip_portrait", "similarity_score": 0.94 } }You are integrating Didit's NFC e-passport reading into a regulated onboarding flow (bank, fintech, crypto exchange, eIDAS-grade public service). NFC chip reading lifts onboarding from document-scan-grade to bank-grade in one extra step on the user's phone.
Five obligations on every onboarding:
1. Read the e-passport / e-ID chip via NFC — DG1 (MRZ), DG2 (portrait), DG11 (personal details).
2. Verify the government signature chain — Passive Authentication (PA) against the ICAO Public Key Directory, Chip Authentication (CA), Active Authentication (AA).
3. Match the live selfie to the high-resolution DG2 portrait extracted from the chip.
4. Run Passive Liveness on the selfie — iBeta Level 1 anti-spoof certified, defeats printed photos, screen replays, masks, and deepfakes.
5. Screen the chip-verified identity against sanctions, Politically Exposed Persons (PEP), and adverse-media lists.
Fallback automatically when NFC is unavailable (no chip, NFC blocked by iOS or by user permission, chip damaged): the workflow drops to high-accuracy MRZ + OCR on the visual page using ID Verification.
Pricing (verified live):
- NFC Reading: $0.15 per chip read
- ID Verification (fallback or always-on belt-and-braces): $0.15 per check
- Passive Liveness: $0.10 per check
- Face Match 1:1: $0.05 per match
- AML Screening: $0.20 per check
- Bundle (NFC + Liveness + Face Match + AML): $0.50 per onboarded user when NFC succeeds; $0.50 also when the workflow falls back to ID Verification
- First 500 KYC verifications free every month, forever
PRE-REQUISITES
- Production API key from https://business.didit.me (sandbox key in 60s, no card).
- Webhook endpoint with HMAC SHA-256 verification using the X-Signature-V2 header and your webhook secret.
- A workflow_id from the Workflow Builder bundling NFC Reading + ID Verification (fallback) + Passive Liveness + Face Match 1:1 + AML Screening.
- The Didit hosted flow or the native SDKs (web SDK, iOS, Android, React Native, Flutter) — NFC chip reading requires the native NFC stack, so plain web-only deployments fall back to MRZ + OCR automatically.
STEP 1 — Create the NFC session
POST https://verification.didit.me/v3/session/
Headers:
x-api-key: <your api key>
Content-Type: application/json
Body:
{
"workflow_id": "<your nfc onboarding workflow id>",
"vendor_data": "<your user id, max 256 chars>",
"callback_url": "https://<your-app>/onboarding/kyc/callback",
"expected_country": "ES",
"metadata": {
"channel": "native_ios",
"purpose": "high_assurance_onboarding"
}
}
Response: 201 Created with the hosted session URL. Open it via the native SDK (iOS NFC requires CoreNFC entitlement) or in the hosted webview; the user taps the e-passport against the phone's NFC reader, the chip data is read in 2-4 seconds.
STEP 2 — The chip-read sequence (handled by the SDK / hosted flow)
Inside the hosted flow, in this order:
a. The user presents the data page so the device camera reads the Machine-Readable Zone (MRZ). The MRZ provides the BAC / PACE key needed to handshake with the chip.
b. The user taps the passport to the phone. PACE (preferred) or BAC handshake establishes a secure session with the chip.
c. The chip returns Data Group 1 (MRZ data — name, DOB, expiry, document number), Data Group 2 (the high-resolution portrait), and Data Group 11 (personal details where available).
d. Passive Authentication verifies the Document Signer Certificate against the country's Country Signing CA via the ICAO Public Key Directory. Chip Authentication and Active Authentication run if supported by the issuing country.
e. The user takes a single selfie (Passive Liveness, no challenge prompts).
f. The selfie is matched 1:1 against the DG2 portrait.
STEP 3 — Read the signed webhook on completion
Didit POSTs to your callback. Session statuses are Title Case With Spaces:
Body (excerpted):
{
"session_id": "<uuid>",
"vendor_data": "<your user id>",
"status": "Approved",
"nfc_verification": {
"status": "Approved",
"passive_authentication": "Approved",
"chip_authentication": "Approved",
"active_authentication": "Approved",
"data_groups_read": [1, 2, 11]
},
"id_verification": { "status": "Approved", "document_type": "passport", "country_code": "ES" },
"liveness": { "status": "Approved" },
"face": { "status": "Approved", "similarity_score": 0.94, "matched_against": "chip_portrait" },
"aml": { "status": "Approved", "hits": [] }
}
Session status enum (exact case):
Approved | Declined | In Review | Resubmitted | Expired | Not Finished | Kyc Expired | Abandoned
Verify the X-Signature-V2 header BEFORE reading the body — HMAC SHA-256 of the raw bytes with your webhook secret.
STEP 4 — Decide
Branch logic:
Approved → onboard the user with bank-grade assurance.
In Review → hold the account, wait for analyst webhook update.
Declined → refuse onboarding, log the decline reason.
Resubmitted → user updated something; re-read the decision.
When face.matched_against === "chip_portrait", you can mark the identity as eIDAS High-grade (Substantial / High depending on your local regulator's reading). When it falls back to "id_document_portrait" (the visual page), it's still bank-grade by document-scan standards but not chip-anchored.
STEP 5 — Fallback paths
iPhones below iPhone 7, or any phone with NFC disabled, or a document without a chip (pre-2014 in some countries) → the workflow surfaces "NFC unavailable" and routes to the ID Verification + MRZ + OCR path. Same hosted URL, same webhook, same statuses. The fallback is configured in the Workflow Builder, not in your code.
Some Android devices won't read every chip due to NFC antenna placement — Didit's iOS / Android SDKs surface a graceful retry hint before failing over to OCR.
STEP 6 — Ongoing monitoring
Enable Ongoing AML at $0.07/user/year to keep the identity fresh. NFC re-reads aren't required for ongoing — the chip data was captured at onboarding and the binding is permanent for the document's validity period.
WEBHOOK EVENT NAMES
- status.updated — session status changed.
- data.updated — session data changed (resubmission, NFC retry, ongoing AML hit).
Verify X-Signature-V2 on every payload. The webhook secret is per-environment — sandbox key is separate from production.
CONSTRAINTS
- Session statuses use Title Case With Spaces (Approved, In Review).
- NFC chip reading requires the native NFC stack — iOS, Android, React Native, Flutter SDKs handle it; pure web falls back to MRZ + OCR.
- The chip portrait (DG2) is far higher-resolution than the visual page — matching the selfie to it is meaningfully more accurate than matching to a phone-camera-captured ID photo.
- Document Signer Certificate trust is anchored to the ICAO Public Key Directory; some countries (eg. small island states) do not publish to the PKD and will return a Passive Authentication warning rather than Approved.
- Default record retention is 5 years post-relationship per the EU AML package.

Didit is infrastructure for identity and fraud, the platform we wished existed when we were building products ourselves: open, flexible, and developer-friendly, so it works as a real part of your stack instead of a black box you integrate around.
One API covers verifying people (KYC, know your customer), verifying businesses (KYB, know your business), screening crypto wallets (KYT, know your transaction), and monitoring transactions in real time, on a stack built to be:
The footprint underneath: 14,000+ document types in 48+ languages, 1,000+ data sources, and 200+ fraud signals on every session. The Didit infrastructure dynamically learns from every session and gets better every day.
Modern passports (and increasingly modern national ID cards in the EU) carry a tiny contactless chip, the same kind of chip you tap to pay with a card. The chip holds:
That last bit is the magic. The chip is cryptographically bound to the issuing country, which means an attacker can't forge or tamper with what it returns, they'd have to forge a government signature. Didit reads the chip via NFC on the user's phone in 2-4 seconds for $0.15 per read.
Three reasons, in order of how much they matter:
For most onboarding flows, document-scan is good enough. For bank, fintech, eIDAS-grade public service, and any flow where a single false positive costs real money, NFC chip reading is the standard control.
The full flow normally takes under 30 seconds end-to-end, pick up the ID, snap the document, snap the selfie, done. That is the fastest in the market. Legacy KYC providers usually take more than 90 seconds for the same flow.
On the back end, Didit returns the result in under two seconds at p99, measured from the moment the user finishes the selfie to the moment your webhook fires. Mobile capture is tuned for slow phones and slow networks: progressive image compression, lazy software development kit load, and a one-tap hand-off from desktop to phone via QR code if the user starts on web.
ICAO Doc 9303 is the international specification for machine-readable travel documents (MRTDs), every modern passport in the world is built to this spec. Three pieces matter for NFC verification:
Didit runs all three and exposes each verdict separately in the decision payload. ICAO Doc 9303 conformant means the chip-read path is the same one border agents use at airport e-gates.
Every session lands on one of seven clear statuses, so your code always knows what to do:
Approved, every check passed. Move the user forward.Declined, one or more checks failed. You can allow the user to resubmit the specific failed step (for example, re-take the selfie) without re-running the whole flow.In Review, flagged for compliance review. Open the case in the console, see every signal, decide approve or decline.In Progress, user is mid-flow.Not Started, link sent, user has not opened it yet. Send a reminder if it sits too long.Abandoned, user opened the link but did not finish in time. Re-engage or expire.Expired, the session link aged out. Create a new session.A signed webhook fires on every status change, so your database always stays in sync. Abandoned and declined sessions are free.
Production data is processed and stored in the European Union by default, on Amazon Web Services. Enterprise contracts can request alternative regions for jurisdictions whose regulators require it.
Encryption everywhere. AES-256 at rest across every database, object store, and backup. Transport Layer Security 1.3 in transit on every API call, webhook, and Business Console session. Biometric data is encrypted under a separate Customer Master Key.
Retention is yours to control. Default retention is indefinite (unlimited) unless you configure shorter, between 30 days and 10 years per application, and you can delete any individual session at any time from the dashboard or the API.
Certifications: SOC 2 Type 1 (Type 2 audit in progress), ISO/IEC 27001:2022, iBeta Level 1 PAD, and a public attestation from Spain''s Tesoro / SEPBLAC / CNMV that Didit''s remote identity verification is safer than verifying someone in person. Full report at /security-compliance.
Didit ships compliant by default for the regulators that matter to identity infrastructure:
Detailed memo, every certificate, every regulator letter: /security-compliance.
Three integration paths, pick whichever fits your stack:
Same dashboard, same billing, same pay-per-success price for all three. Step-by-step guide at docs.didit.me/integration/integration-prompt.
Three common failure modes, all handled by the workflow:
The fallback path is the same /v3/session/, same webhook, same statuses. The decision payload tells you which path succeeded so you can route on it, face.matched_against === "chip_portrait" for the NFC path, "id_document_portrait" for the OCR fallback. Bank-grade workflows can reject the OCR fallback and require a fresh attempt on a different device.
Under eIDAS 2, the EU's electronic-identification framework, a chip-verified e-passport with biometric matching can support Substantial or High assurance, depending on the workflow's surrounding controls.
Didit's role is to deliver the underlying identity-binding evidence:
Whether the complete flow reaches Substantial or High depends on the consuming wallet, the trust framework, and the regulator's interpretation in your country. Didit is the only KYC provider with a formal EU-government attestation, Spain's Treasury, Banco de España, and SEPBLAC jointly attested the service as safer than in-person verification. That report is the most-cited starting point for an eIDAS High discussion.
Most NFC providers price between $1.50 and $5.00 per chip read, often with minimums in the thousands of euros per month and per-country surcharges for chip-signing-cert subscriptions. The Onfido / Jumio / Veriff archetype.
Didit's published price is $0.15 per NFC chip read + $0.50 for the full bundle (NFC + Liveness + Face Match + AML). No floor, no minimum, no per-country surcharge. The first 500 verifications free every month absorbs most pilots entirely.
That's roughly 10-30× cheaper than the incumbent stack on the same regulatory output. At a 10,000-user month, the saving versus a $2.00-per-chip incumbent is around $18,500. At European-bank volumes (100,000+ KYCs / month) the saving compounds into mid-six-figures annually. Full pricing at /pricing.
