Know Your Customer (KYC): Why, How, and With What Solutions?

KYC, or “Know Your Customer”, has become essential in many sectors where trust is now a core value in business relationships. Whether in banking, insurance, fintech, or even telecommunications, verifying customer identity is no longer just a regulatory requirement — it’s a guarantee of professionalism, security, and accountability. But why has KYC become so crucial? And how can businesses balance compliance, efficiency, and user experience?

What is KYC? A Clear Definition

« Know Your Customer » refers to all the procedures put in place to verify a customer’s identity before establishing a business relationship. This process goes far beyond simply collecting documents — it’s a proactive approach to ensure that each customer is who they claim to be and that they are not involved in illegal activities such as money laundering or terrorist financing.

Why Is KYC Critical for Businesses?

It addresses several key challenges:

• Regulatory compliance: Meeting national and international requirements to combat money laundering and terrorist financing.
• Combating fraud: Reducing risks of identity theft and document fraud.
• Reputation protection: Avoiding sanctions and maintaining the trust of customers and partners.
• Better customer knowledge: Enabling companies to tailor services and anticipate risks.

Failure to comply with KYC obligations can expose companies to fines, penalties, and even bans on doing business.

For Who?

Although banking and insurance were the first sectors impacted, KYC has now become standard across a wide range of industries — including fintech, payment providers, crowdfunding platforms, telecom operators, online gaming, real estate, and healthcare. The list keeps growing as regulations evolve and new risks emerge.

It’s also important to distinguish between KYC, which applies to individual customers, and KYB (“Know Your Business”), which focuses on verifying corporate clients.

What Documents Are Required?

Before we get into the list, it’s important to highlight that collecting and verifying these documents is central to the KYC process. By law, companies must verify customer identities before opening any business relationship.

• For individuals: identity card, passport, driver’s license, proof of address (such as a utility bill or rental receipt), residence permit, etc.
• Special case: politically exposed persons (PEPs) require enhanced due diligence (EDD) to manage higher risk levels.
• For companies: articles of association, Kbis extract (company registration), proof of legal representatives’ identities, etc.

Regulatory Obligations

In Europe, the Fifth Anti-Money Laundering Directive (AMLD5) was adopted on 30 May 2018 and published on 19 June 2018. It was transposed into the national laws of Member States by 10 January 2020. This directive strengthened and extended KYC obligations to new sectors: beyond banks, insurance companies, and payment institutions, it expanded the scope to include non-financial sectors like online gaming, real estate, crypto-assets, and luxury goods.

It’s important to note that KYC requirements were already introduced under earlier directives — notably the third directive (AMLD3) in 2005 and the fourth directive (AMLD4) in 2015, which established the foundations of customer identification and due diligence. AMLD5 didn’t create « Know Your Customer » obligations from scratch, but it reinforced requirements and expanded the number of affected entities.

The KYC Verification Process: Key Steps

In practice, the KYC process involves several key stages:

• Collecting information and supporting documents
• Verifying document authenticity and performing consistency checks
• Carrying out regular reviews and applying remedial measures when anomalies are detected

While these tasks were traditionally done manually, automation and digitalization have transformed the landscape — making checks faster, more reliable, and more cost-effective.

KYC in the Digital Age

Digitalization has reshaped how companies implement KYC. Identity verification no longer depends on physical document collection; instead, it uses innovative technologies that make the process quicker, safer, and smoother for the user.

The Rise of eKYC

The digital era has given birth to eKYC (electronic KYC). Thanks to artificial intelligence, biometrics, and facial recognition, companies can now:

• Automatically scan and analyze identity documents
• Match a user’s selfie to the document photo
• Detect document fraud and identity theft attempts

A Simplified and Secure Customer Journey

Opening a digital account, once a complex and time-consuming process, can now be completed in just minutes on a smartphone or computer. Users upload their supporting documents, take a short video or selfie, and receive near-instant validation.

For companies, this delivers:

• Lower operational costs
• Reduced drop-off rates during onboarding
• Improved compliance through automated controls

IAM Solutions and Their Role in « Know Your Customer »

Identity and Access Management (IAM) solutions play a crucial role in supporting KYC:

• They verify customer identities during onboarding and later logins.
• They incorporate multi-factor authentication (MFA), behavioral analytics, centralized identity management, and access traceability.

Modern IAM platforms, such as TrustBuilder, orchestrate identity flows, automate checks, and integrate with KYC systems to strengthen security, compliance, and user experience.

Key Takeaways

• KYC is essential for regulatory compliance, fraud prevention, and customer trust.
• eKYC and IAM technologies have made onboarding faster, safer, and more seamless.
• Businesses must adapt their solutions to meet regulatory requirements and manage risk levels effectively.
