Marketplaces
Online marketplaces are only as strong as the trust between the people on them. Fake accounts, synthetic identities, fraudulent sellers, and stolen payment information erode that trust faster than any competition can. Microblink helps ecommerce platforms, rideshare and delivery apps, peer-to-peer sharing platforms, and social commerce networks verify who is actually on their platform.
Two-sided platforms face a fraud problem that’s structurally harder than most. Fraudsters don’t just attack buyers, they attack sellers, drivers, and service providers too. They create fake accounts to abuse promotions. They use stolen payment information to place orders they know will be disputed. They exploit peer-to-peer trust to commit crimes that damage real users and platform reputation alike. And as AI-generated identities become more accessible, the sophistication of these attacks is rising faster than manual review can keep up with.
Regulatory complexity compounds the pressure. Marketplace operators expanding across jurisdictions face age verification requirements, KYC obligations for high-value transactions, and trust and safety standards that vary by market. Microblink’s Identity Intelligence OS helps marketplace teams build a continuous identity layer that adapts to all of it — protecting every side of the transaction without creating the friction that drives real users away.
SECURING THE CUSTOMER JOURNEY
Microblink helps marketplaces verify the real buyers and sellers on both sides of every transaction so they can stop fraud and protect their community without slowing legitimate onboarding. Microblink’s identity decisioning layer covers the moments that define trust and fraud exposure on two-sided platforms:
Fake accounts and bot-driven signups are the entry point for most marketplace fraud.
Microblink verifies government-issued IDs, matches faces to documents, and applies adaptive risk checks at account creation — stopping synthetic identities and fraudulent buyers before they enter the ecosystem.
Legitimate users move through quickly. Suspicious signups get the scrutiny they warrant.
The seller side of a marketplace carries its own identity risk.
Fraudulent sellers, impersonating drivers, and unverified service providers create liability for platforms and harm for buyers.
Microblink verifies the real person behind a seller account, a driver profile, or a freelancer listing — combining document verification with biometric matching to confirm the person is who they claim to be.
The transaction moment is where stolen payment information, first-time card additions, and account takeover attempts concentrate.
Microblink adds trust to high-risk purchases and unusual transaction patterns by linking the real account holder to the real payment instrument — reducing chargebacks and manual review volume without disrupting checkout for legitimate buyers.
Friendly fraud, refund abuse, and social engineering increasingly hit post-purchase workflows.
Microblink strengthens identity controls on refund claims, account changes, and dispute flows so trust and safety teams can resolve legitimate issues quickly while blocking abuse patterns that are expensive to fight at scale.

The Microblink Difference
Why Microblink
Trust and safety teams need stronger defenses. Growth teams need fewer drop-offs at signup and checkout. Microblink takes a risk-based approach — applying stronger checks only when signals warrant them. Low-risk users move through quickly. Suspicious signups, new payment methods, and high-value transactions trigger the right level of verification at the right moment.
In March 2026, Microblink became the only identity verification vendor to meet all performance thresholds in the U.S. Department of Homeland Security's RIVR evaluation. 0.00% System Error Rate. 3.15% Document False Reject Rate. 0.88% Document False Accept Rate. Every other participating vendor failed at least one threshold. For marketplace platforms running high-volume identity checks across millions of accounts, that accuracy advantage reduces false declines on legitimate users.
Marketplace fraud doesn't stop after onboarding. Microblink helps teams move beyond one-time checks by continuously evaluating identity, behavior, and context across the account lifecycle — catching account takeover, seller fraud escalation, and abuse pattern changes that a static signup check can never see.
Fraudsters attacking marketplace platforms rarely rely on a single signal. Microblink combines document verification, facial biometrics with liveness detection, and payment card intelligence into a single decisioning framework — the only identity platform with cross-modal liveness across docs, biometrics, and payment cards. AI-generated identities and deepfakes that defeat single-signal systems are stopped by the intersection of all three.
Expanding into new markets means dealing with different document types, fraud patterns, and regulatory requirements without rebuilding verification workflows from scratch. Microblink supports 2,500+ ID document types across 195+ countries and territories, giving marketplace teams one consistent trust layer wherever their platform operates.
Fraudulent seller and service provider accounts damage both platform reputation and individual buyers before a single transaction takes place. Microblink verifies the real identity behind every new account.
Loyal buyers with stored payment information and purchase history are the most attractive fraud targets. Microblink adds step-up verification to login, password reset, and payment method change events so that confirmed account holders complete those actions, not fraudsters.
Chargebacks on marketplace transactions are costly not just as direct losses but as operational drag on trust and safety teams. Microblink helps marketplace operators confirm the real identity behind risky transactions and unusual account behavior before fraud turns into a dispute.
Microblink provides fast, reliable age and identity verification at the point of purchase or account creation, meeting regulatory standards across jurisdictions without adding meaningful friction for users who qualify.
Fraud and trust and safety teams need defenses that scale with the platform. Growth teams need onboarding flows that convert in every market. Compliance teams need verification that holds up across jurisdictions. Microblink serves all three by turning identity into a continuous layer of platform intelligence rather than a one-time friction gate at signup.

Microblink verifies government-issued IDs, matches faces to documents, and applies adaptive risk checks at signup — stopping synthetic identities, bot-driven account creation, and fraudulent seller profiles before they enter the platform. For seller and driver onboarding specifically, document verification and biometric matching confirm the real person behind the account. The same checks apply to buyer signups where risk signals warrant them, without blanket friction for the majority of legitimate users.
Linking the real account holder to the real payment instrument at the moment of high-risk transaction is the primary lever. Microblink adds a verification layer to first-time card additions, unusual purchase patterns, and large transactions — confirming the person initiating the payment is who they claim to be. The result is a stronger fraud signal that reduces chargeback rates without forcing approval rates down by over-blocking legitimate buyers.
Microblink supports 2,500+ ID document types across 195+ countries and territories, covering national IDs, passports, driver’s licenses, and residence permits from virtually every market. Marketplace operators expanding across borders can run consistent identity workflows across all regions without building separate verification stacks or fallback flows for unfamiliar documents.
The Microblink Platform integrates via API and SDK for web and mobile, with a no-code hosted UI option for faster deployment. SDKs are as small as 2.5MB — up to 6× smaller than alternatives — so they don’t add meaningful weight to mobile signup flows. Adaptive workflows allow teams to configure risk thresholds without engineering involvement, applying stronger checks when needed and lighter checks for low-risk returning users.
Designed for modern digital onboarding, Microblink helps businesses prevent fraud, reduce friction, and maintain compliance without slowing down the customer experience.
