The identity verification industry has historically sold monolithic bundles: document check plus biometric match plus sanctions screening plus address verification, packaged together at a flat per-verification price. For a decade, this was the only option. It is no longer the best one.

The Problem with Bundles

Monolithic verification bundles create three problems for growing businesses:

You pay for checks you do not need. A peer-to-peer marketplace that needs document verification and biometric matching does not need address verification — but the bundle includes it, and the price reflects it.

You cannot customize the workflow. Every user goes through the same verification process regardless of risk level. A returning customer re-verifying after a password reset gets the same treatment as a first-time registrant from a high-risk jurisdiction.

You are locked into one provider's capabilities. If the provider's sanctions screening is excellent but their biometric matching is average, you are stuck with both.

What Modular Means in Practice

A modular identity verification platform exposes individual verification capabilities as discrete, composable building blocks:

• Document verification — authenticate and extract data from government-issued IDs
• Biometric matching — compare a selfie to the document photo
• Liveness detection — confirm a real person is present
• Sanctions screening — check against configurable watchlists
• Address verification — confirm a physical address
• Age verification — confirm the user meets a minimum age threshold
• Document storage — securely store and manage verified documents

Each check operates independently. You compose them into workflows that match your specific requirements.

Composing Workflows

Different use cases require different verification compositions:

FinTech onboarding: Document verification + Biometric matching + Liveness detection + Sanctions screening

Online gaming registration: Document verification + Biometric matching + Age verification

Real estate document signing: Biometric matching + Liveness detection (identity already verified at transaction start)

Employee verification: Document verification + Biometric matching

High-risk transaction: All available checks + Enhanced due diligence

The workflow is configured through the API. No code changes are required to add or remove checks — just update the request payload.

The Cost Advantage

Modular pricing means you pay only for the checks you use. The math is compelling:

Monolithic bundle: $4.00 per verification (document + biometric + liveness + sanctions + address)

Modular equivalent (FinTech): $0.40 (document) + $0.30 (biometric) + $0.15 (liveness) + $0.20 (sanctions) = $1.05 per verification

Modular equivalent (Gaming): $0.40 (document) + $0.30 (biometric) + $0.10 (age) = $0.80 per verification

At 100,000 verifications per month, the difference between $4.00 and $1.05 per verification is $295,000 per month — $3.54 million annually. That is not optimization. It is a fundamentally different cost structure.

Progressive Verification

Modularity also enables progressive verification — starting with basic checks and adding more as the user's risk profile evolves:

At registration: Document verification + Biometric matching → user is onboarded

At first transaction: Sanctions screening is added → user is cleared for financial activity

At threshold crossing: Enhanced due diligence checks → user is cleared for high-value transactions

Each step adds assurance without requiring the user to repeat earlier steps. The verification builds progressively, matching the relationship's evolution.

How deepidv Implements Modularity

deepidv was built from day one as a modular platform. Every verification capability is:

• Independently callable through a single, consistent API
• Independently priced with no bundling requirements
• Composable into workflows through simple API configuration
• Consistent in response format regardless of which checks are included

The platform also provides workflow templates for common use cases — FinTech onboarding, gaming registration, real estate closing — that can be used as-is or customized.

The Bigger Picture

The shift from monolithic to modular is not just about cost savings. It is about building identity verification infrastructure that adapts to your business rather than forcing your business to adapt to it.

Requirements change. Regulations evolve. Markets expand. A modular architecture ensures that your verification infrastructure evolves with you — without rip-and-replace migrations, without vendor lock-in, and without paying for capabilities you do not use.

The future of identity verification is not one-size-fits-all. It is build-what-you-need, when you need it.
