What Is KYC (Know Your Customer)
KYC (Know Your Customer) is the process of verifying the identity of individuals before they can access financial services. It is a foundational requirement in payment infrastructure, ensuring that users are who they claim to be and that transactions can be conducted within regulatory frameworks.
In payments, KYC is the control layer that sits before any account is activated or any funds are moved.
What Is KYC and What Does It Mean in Practice
The meaning of KYC becomes clear when looking at how users are onboarded into financial systems.
KYC focuses on identifying and verifying individuals, typically through a combination of documents, data checks, and risk assessment processes.
In practice, this includes:
- Collecting personal information such as name, address, and date of birth
- Verifying identity documents (passport, national ID, driver’s license)
- Performing biometric or liveness checks where required
- Screening individuals against sanctions lists and watchlists
The goal is to establish a verified identity profile that can be used to monitor and approve financial activity.
How KYC Differs from Kyb
KYC and KYB are closely related but apply to different entities within the payment ecosystem.
- KYC: verifies individuals
- KYB: verifies businesses and their ownership structures
In a typical payment flow:
- KYC applies to individual users, account holders, or sole traders
- KYB applies to companies and legal entities
- Both may be required together when verifying business owners or directors
The distinction matters because each process involves different data, documentation, and regulatory requirements.
What KYC Involves in Payment Systems
KYC is not a one-time check. It is part of an ongoing compliance framework.
The process typically includes:
- Initial verification: confirming identity before account access is granted
- Risk profiling: assigning a risk level based on geography, activity, and profile
- Ongoing monitoring: tracking transactions for suspicious behaviour
- Periodic updates: refreshing identity data when required
For payment providers, KYC ensures that every individual interacting with the system is identifiable and accountable.
Why KYC Matters For Fintech And Marketplaces
For fintech platforms and marketplaces, KYC is a critical requirement when onboarding users, sellers, or participants.
Without proper KYC:
- Platforms cannot legally process payments
- Fraud and financial crime risk increases
- Regulatory exposure extends to the platform operator
With KYC in place:
- Users are verified before transactions occur
- Payment flows operate within compliance frameworks
- Platforms can scale without compromising regulatory obligations
KYC becomes part of the product experience, not just a compliance step.
How Merge Covers KYC And KYB Together
Merge provides a unified compliance layer that includes both KYC and KYB as part of its infrastructure.
In practice:
- Individual users are verified through KYC processes
- Businesses are verified through KYB checks
- Ownership structures are linked across both layers
- AML and sanctions screening apply continuously
This means fintechs and marketplaces building on Merge do not need to assemble separate compliance systems for individuals and businesses.
Instead, identity verification, business verification, and transaction monitoring are handled within a single framework.
Why This Matters For Platform Builders
Managing KYC and KYB independently can create fragmentation:
- Multiple providers for identity checks
- Separate workflows for individuals and businesses
- Inconsistent compliance standards across regions
By combining both within one system, platforms can:
- Simplify onboarding flows
- Maintain consistent compliance standards
- Reduce operational overhead
- Scale across markets more efficiently
This becomes increasingly important as platforms expand into new jurisdictions with different regulatory expectations.
FAQ
What is KYC?
KYC stands for Know Your Customer, the process of verifying a person's identity before granting access to financial services, covering document collection, sanctions screening, and ongoing transaction monitoring.
What is KYB?
KYB stands for Know Your Business, the equivalent of KYC applied to companies. It verifies a business is legitimately registered and identifies the individuals who ultimately own or control it, who then go through KYC themselves.
What is a PEP check?
A PEP check screens whether an individual is a Politically Exposed Person, someone in a prominent public role carrying a higher risk of financial crime. It is a standard part of any KYC sanctions and watchlist screening process.
What is enhanced due diligence?
Enhanced due diligence is a deeper level of KYC applied to higher-risk customers or transactions. It requires more documentation, additional background checks, and closer ongoing monitoring beyond what a standard KYC process would involve.
What is ongoing monitoring in KYC?
Ongoing monitoring is the continuous review of a customer's transactions after onboarding. Platforms must flag activity inconsistent with what the customer originally stated, it is a standing regulatory obligation, not a one-time check.
