How Much KYC Is Enough? A KYC Checklist for Prepaid and Payment Service Providers

As digital payment services continue to evolve, KYC is becoming more than a one-time identity check. It is increasingly connected to how payment service providers manage user identity, fraud risks, and day-to-day operations throughout the customer lifecycle.

Today, providers need to consider a much broader range of questions: How should identity documents be verified? How can identity theft and fraudulent transactions be prevented? How should international users be verified? And how can the performance and operational cost of an existing KYC process be evaluated?

To explore these challenges, ARGOS is launching a new eight-part series: The Practical eKYC Guide for Payment Service Providers.

Over the next month, we will cover key topics including KYC checkpoints for payment services, identity document OCR and fraud detection, identity theft prevention, KYC for international customers, evaluating existing eKYC solutions, KYC operational costs, and identity verification considerations for emerging financial services such as stablecoins and digital assets.

Rather than focusing solely on individual technologies, this series will look at KYC from the perspective of real-world payment services and operations. In the final article, we will bring these topics together to outline the overall framework businesses should consider when building or upgrading their eKYC infrastructure.

We begin with a fundamental question:

How much KYC does a payment service actually need, and what should businesses check in their existing identity verification process?

Why Payment Service Providers Should Revisit Their KYC Process

Identity verification is already a familiar part of digital financial services.

However, as prepaid payment services, payment gateways, digital wallets, and other payment services expand, the more important question is no longer simply:

“Do we verify our users?”

Instead, businesses need to ask:

“When should we verify them, and what level of verification is appropriate at each point?”

In a remote environment, an account created with legitimate information may later be used by someone else. Even when an identity document has been submitted, businesses may still need to determine whether the document itself is legitimate and whether the person presenting it is actually its owner.

So, what should payment service providers examine in their current KYC processes?

A customer journey does not end at account creation.

Depending on the service, users may register a payment method or bank account, add funds to a prepaid balance, withdraw funds, increase transaction limits, or change personal and settlement information.

At each of these points, one question becomes increasingly important:

How confident are you that the person using the service is the same person who was originally verified?

For example, even if an account was created using legitimate information, initial onboarding verification alone may not be enough to identify cases where the account is later transferred, shared, or compromised.

This is why KYC should not be viewed as a single verification step. Instead, payment providers should consider identity risks across the entire customer journey.

When Should Payment Services Verify Their Users?

Requiring every user to complete the same level of verification at every stage is not necessarily the best approach.

The more friction added to the verification process, the greater the potential impact on legitimate user conversion and experience.

A better starting point is to identify where identity-related risks increase throughout the customer journey.

Here are several common checkpoints.

Account Registration and Initial Onboarding

This is the first stage where a business establishes who the user is.

Depending on the service and its risk profile, basic personal information may be sufficient in some cases, while others may require identity document-based verification.

Prepaid Top-Ups and Transaction Limit Increases

When transaction amounts or account capabilities increase, businesses may need to determine whether the identity information collected during initial onboarding remains sufficient.

Additional identity verification may also be appropriate when moving a user from a limited or lower-verification account to a fully verified account with higher transaction limits.

Withdrawals and Bank Account Registration or Changes

When funds are withdrawn or transferred to a bank account, accurately establishing the relationship between the account user and the transaction becomes increasingly important.

These moments can warrant stronger verification depending on the service structure and associated risk.

Changes to Personal or Critical Account Information

When users change important personal information, authentication methods, or other sensitive account details, businesses may need to confirm that the person making the request is the same legitimate user who previously completed verification.

The goal is not to create as many verification steps as possible.

Instead, businesses should identify where identity risk increases and apply the appropriate level of verification at those moments.

Is Collecting an Identity Document Enough?

If a payment provider uses document-based KYC, the next question is how those documents are actually being verified.

OCR can extract information such as a user's name, date of birth, and document number from a captured identity document.

But OCR is fundamentally designed to read information from a document.

For a more reliable remote identity verification process, businesses should consider additional layers of verification:

Data Extraction → Document Authenticity and Fraud Detection → Face Match → Liveness Detection

This distinction matters.

Reading information from an identity document is not the same as verifying that the document and the person presenting it can be trusted.

This is also why comparing eKYC solutions based solely on whether they support OCR may not provide enough information to evaluate the strength of the overall verification process.

Is the Person Presenting the ID Its Actual Owner?

Even when a legitimate identity document is submitted, another question remains:

Is the person currently using the service actually the owner of that document?

In cases involving stolen identities or account misuse, there may be nothing inherently wrong with the identity document itself.

This is where Face Match and Liveness Detection become important.

Face Match compares the facial image on the identity document with the face of the person completing verification to determine whether they are likely to be the same person.

Liveness Detection helps determine whether a real person is present during verification and can help identify attempts involving photos, replayed videos, or other presentation attacks.

Remote KYC therefore needs to go beyond checking a document.

A stronger verification flow connects:

Identity Document → Document Integrity → Document Owner → Actual User

International Users Make KYC More Complex

When payment services expand to international customers, identity verification becomes even more complex.

Supporting only domestically issued identity documents is very different from processing passports and identity documents issued across multiple countries.

Services such as prepaid cards for international travelers, cross-border remittance, currency exchange, and global payments may need to process a wide range of passports, driver's licenses, and national identity cards.

In this environment, simply checking whether a solution supports passport OCR is not enough.

Businesses should also consider:

• Does the solution support identity documents from the countries where our customers are located?

• Can it accurately extract data from different passports and identity document formats?

• Can it detect potential document fraud or manipulation?

• Can it compare the portrait on the identity document with the actual user?

• Can failed verification attempts and retries be effectively managed?

For businesses planning international expansion, scalability is another important consideration.

A KYC infrastructure should be able to support new countries and identity document types as the service expands without requiring extensive redevelopment every time a new market is added.

Already Using eKYC? You Still Need to Measure Its Performance

For payment providers that already use identity document OCR or an eKYC solution, adding another solution should not necessarily be the first step.

Start by measuring the performance of the current verification environment.

Ask questions such as:

What is our current verification completion rate?

At which stage do the most users abandon verification?

How frequently are users required to recapture their identity documents?

What percentage of cases require manual review?

How does the verification success rate of international customers compare with domestic customers?

How effectively are manipulated documents and abnormal verification attempts being detected?

The fact that a business has already implemented KYC is less important than whether its current process can allow legitimate users to complete verification efficiently while identifying higher-risk users and attempts.

KYC Checklist for Payment Service Providers

Use the following questions to review your current identity verification process.

KYC Coverage

• Which users are required to complete KYC?

• At which points in the customer journey is identity verified?

• Do higher-risk transactions trigger additional verification?

Identity Document Verification

• Are you relying on OCR alone?

• Do you verify document authenticity or detect potential manipulation?

• Do you compare the identity document photo with the actual user?

• Is Liveness Detection included in the process?

KYC for International Customers

• Can you support international identity documents beyond passports?

• Can new markets be supported without extensive additional development?

• Do you separately monitor verification failure rates for international customers?

Operational Efficiency

• Do you measure verification completion rates?

• Do you track the percentage of cases requiring manual review?

• Do you measure customer support requests caused by verification failures?

• Are multiple identity verification solutions being operated separately?

If some of these questions are difficult to answer clearly, there may be areas in your current KYC process that require further review.

Effective KYC Is About the Verification Framework, Not More Verification Steps

Improving KYC does not mean adding more verification steps for every user.

What matters is designing a framework that answers four questions:

Who should be verified?
When should they be verified?
Which risks need to be identified?
How much of the process can be automated?

ARGOS ID check enables businesses to build an end-to-end remote KYC flow that brings together identity document OCR, document verification, Face Match, Liveness Detection, and global identity document verification.

If you are reviewing your existing payment service verification process or considering additional capabilities such as international KYC, document fraud detection, or facial verification, the first step is to evaluate which level of KYC is appropriate for your current service and risk environment.

Next in the series: We will take a closer look at the criteria payment service providers should consider when comparing eKYC solutions, including identity document OCR, document authenticity and fraud detection, Face Match, Liveness Detection, and global identity document coverage.
