Choosing your KYC solution: the 8 criteria of real identity verification

In short: choosing a KYC solution in 2026 comes down to eight criteria: the richness of cross-referenced signals beyond the document itself, biometrics and NFC chip reading, the detection of AI-generated fakes, the analysis of contact details (phone, email, IP), response time, compliance (AML/CFT, AMLD6, eIDAS 2.0), the explainability of the AI, and data sovereignty.

‍

Identity verification has changed in nature: a fake document generated by AI now passes a visual check in a few seconds, and the European wallet (eIDAS 2.0) will reshuffle the deck from late 2026. Here is how to evaluate a KYC solution, with, for each criterion, the question to ask in a demo.

‍

1. Cross-referenced signals, not just a document

‍

A KYC that only reads an identity document verifies the document, not the person. The most robust solutions cross-reference hundreds of data points from a few fields (name, email, phone): the age of digital footprints, real contactability, linked accounts, type of phone operator. A recent identity "with no digital past" is the most common fraud pattern, and it is invisible to a document check alone.

‍

Question to ask: "How many signals do you cross-reference from the customer's contact details alone, and which ones weigh most in the score?"

‍

2. Biometrics, liveness and NFC reading

‍

The core trio: comparing the face to the document (face matching), proof that the person is alive and present (liveness), and, increasingly decisive, NFC reading of the document's chip, which verifies a state-signed identity rather than a falsifiable image. Against deepfakes, the chip is the only element that no generative AI can counterfeit.

‍

Question to ask: "Do you support NFC reading of documents, and how does your liveness hold up against deepfakes and injection attacks?"

‍

3. Detecting AI-generated fakes

‍

Image generators produce credible identity documents, payslips and bank statements in a few seconds. Human visual checks are no longer enough: demand automated forgery analysis that cross-references file structure, typographic consistency, metadata and consistency between the documents in a single file.

‍

Question to ask: "Run the test in front of me with an AI-generated document."

‍

4. Analysing contact details: phone, email, IP, device

‍

A virtual prepaid number, an email created three days ago, an IP inconsistent with the declared address, three different devices in 24 hours: each of these signals, harmless in isolation, becomes telling when they converge. Also check for Mobile ID, querying the operator to confirm that the line is actually registered in the applicant's name.

‍

Question to ask: "Can you confirm with the operator that the mobile line belongs to the applicant, and for what share of the market?"

‍

5. Response time and journey friction

‍

Every step added to the journey costs legitimate customers: up to 40% abandonment on journeys that demand too many documents. A good KYC adapts the level of control to the real risk of the file: light for healthy profiles, reinforced for risky ones. Demand the actual response time and the false positive rate observed with comparable clients.

‍

Question to ask: "What is your observed false positive rate, and how does the journey adapt to the risk level?"

‍

6. Compliance, and readiness for the European wallet

‍

AML/CFT, GDPR, AMLD6 (applicable July 2027): the baseline. But 2026 adds a structural question: the arrival of the EUDI Wallet (eIDAS 2.0), which banks and telecom operators will be required to accept from November 2027. The wallet will only cover part of the need (basic identity, B2C, digital only), so your solution must orchestrate both journeys: the wallet when it exists, classic KYC otherwise.

‍

Question to ask: "How do you orchestrate the European wallet and the classic journey within a single flow?"

‍

7. Explainability of the AI

‍

If the score contributes to an approval or refusal decision, the AI Act and your national supervisor (ACPR in France, BaFin in Germany, DNB in the Netherlands) require you to be able to justify it. Every score must be returned with its reasons, and the audit trail must be exportable. An unexplainable refusal is an indefensible refusal, in an audit as much as in front of the customer.

‍

Question to ask: "For this refused file, give me the exact reasons behind the score, in an exportable format."

‍

8. Sovereignty and extensibility

‍

KYC data is sensitive personal data: hosting in the EU, with no transfer outside the Union. And anticipate what comes next: the same file will call for KYB (if the customer is a business), IBAN verification, a creditworthiness score. An API that covers these adjacent cases avoids stacking up integrations.

‍

Question to ask: "Where is the data processed, and what does the same contract cover beyond KYC?"

The decision grid at a glance

‍

• Signals: the minimum, document reading; the differentiator, hundreds of cross-referenced data points (footprints, operator, linked accounts).
• Biometrics: the minimum, face matching; the differentiator, anti-deepfake liveness + NFC reading.
• AI fakes: the minimum, visual check; the differentiator, automated multi-document detection.
• Contact details: the minimum, valid format; the differentiator, Mobile ID, IP, device, email age.
• Journey: the minimum, response < 1 min; the differentiator, 2-5 s, risk-proportionate controls.
• Compliance: the minimum, AML/CFT / GDPR; the differentiator, AMLD6-ready + EUDI Wallet orchestration.
• AI: the minimum, a score; the differentiator, score + exportable reasons (AI Act).
• Data: the minimum, EU hosting; the differentiator, sovereign hosting in a single EU country + KYB/IBAN/creditworthiness extension.

How Meelo meets these 8 criteria

‍

Meelo's Identity Fraud Score cross-references more than 400 signals from four fields (last name, first name, email, mobile) and returns an explained score in 2 to 5 seconds: digital footprints, consistency of contact details, Mobile ID. Add face matching, liveness, NFC reading, automated document analysis and orchestration of the European wallet. Explainable AI audited by IEEE, data hosted in France, and the same API covers KYB, IBAN and creditworthiness. Documented results: 93% of fraud identified at customer onboarding, 2.5% false positives. To test these controls on your own files, you can schedule a demo.

FAQ

‍

What is a KYC solution?

A KYC (Know Your Customer) solution automates the verification of a customer's identity at customer onboarding: document checks, biometrics, data cross-referencing and risk scoring, to meet AML/CFT obligations and block identity fraud.

‍

Who is required to perform KYC?

All entities subject to AML/CFT obligations: banks, insurers, fintechs, credit and payment players, crypto platforms (MiCA), and more and more sectors via AMLD6 (applicable July 2027).

‍

How long does an automated KYC check take?

From 2 to 5 seconds for the best solutions, versus 48 hours to several days with manual processing. The right indicator includes the files escalated to an analyst.

‍

Will the European wallet (eIDAS 2.0) replace KYC?

No. The wallet will certify basic identity in digital B2C, but it covers neither creditworthiness, nor dynamic fraud (deepfakes, front men), nor KYB, nor in-store journeys, nor AMLR due diligence obligations. Both need to be orchestrated.

‍

How can you detect a fake document generated by AI?

Through automated analysis that cross-references file structure, typographic consistency and metadata, complemented by NFC reading of the chip (which cannot be forged) and cross-checking the declared data against external sources.
