Verify & Pay: Auditability without Checkout Drop-Offs

Concordium

October 2, 2025

Identity checks are slowing down online commerce. Concordium Verify & Pay is being developed to combine verification and payment into one step to reduce friction while keeping transactions auditable, and users onboard.

‍

Payment service providers (PSPs) and merchant platforms of age-restricted goods–alcohol, tobacco, chemical substances, adult content and the like–face a growing challenge: regulators demand strict identity checks, while consumers expect instant, hassle-free checkouts. Payment flows are already a hurdle, so adding verification to the mix, where ID checks and billing are split across screens, only increases the friction. And friction kills sales conversion.

The consequences are stark. As per the data collected by Bayard Institute, the average online shopping cart abandonment rate is around 70.22%, meaning roughly 7 out of 10 customers leave before completing a purchase. On mobile, the figures are even higher. Some reports peg mobile abandonment as high as 85.65%. While the reasons for drop-offs vary, complex checkouts are the major culprits.

In regulated verticals, ID checks and KYC screens are added obstacles. No one enjoys extra screens, document uploads or validation delays. And many users won’t wait. For PSPs and merchants, the result is leakage at every step, invisible but costly.

Concordium’s Verify & Pay is being developed to solve this. It aims to bring together two functions—identity verification and payment—into one simple action.

Two Functions, One Flow

Typically, identity checks sit in one window, payment in another, which often leads to confusion and drop-offs. With Verify & Pay, identity validation and payment are condensed into a single, unified flow. No switching screens. No redundant steps.

Here’s how it will work in practice:

At checkout, users click the Concordium Pay button
A wallet interface opens, shows what needs to be verified, and requests approval
Once approved, both user eligibility (i.e. age or jurisdiction) and payment settle instantly in one atomic transaction.

For PSPs and merchant platforms, this architecture means you no longer have to manage separate KYC modules or complex identity handoffs. Verify & Pay is built on Concordium’s protocol-level zero-knowledge proof identity and token infrastructure, making compliance non-optional, but also seamless and privacy-preserving.

How Merchants Benefit

For merchants operating in regulated sectors, Verify & Pay removes one of the biggest sources of checkout friction: bolted-on identity checks. Wine and alcohol retailers will be able to replace pop-up disclaimers and manual checks with cryptographic proof-of-age, allowing only eligible customers to complete their purchases quickly and privately. Adult content platforms could use ZKP technology to verify user eligibility without ever storing passports or personal data, eliminating the risk of breaches or misuse. Meanwhile gaming and gambling sites could instantly confirm both age and jurisdiction, ensuring every transaction is compliant and audit-ready without aggravating the user experience.

Essentially, Verify & Pay turns compliance from a conversion blocker into a built-in advantage that’s faster, safer and seamlessly auditable. More importantly, it builds trust between merchants and consumers: merchants know every transaction is verified and valid, and consumers can feel confident that their privacy is protected.

PSPs: Turning Auditability Into A Competitive Edge

For PSPs, value and success is not measured by security or compliance, but rather how much revenue is retained by their merchants. Every failed ID check, every abandoned cart, and every added click or screen chips away at conversion. Verify & Pay has the potential to change that equation. By merging identity verification and payment into one flow, it recovers revenue lost to verification drop-offs and streamlines compliance flows across regulated sectors. It also reduces infrastructure complexity, cutting costs and time spent managing KYC and payment modules. This unified, on-chain flow also gives PSPs a technical advantage, enabling them to provide a frictionless system that preserves user privacy, ensures immutable audibility, and keeps merchants compliant-ready without compromising user experience.

The Bigger Picture

Verify & Pay not only simplifies regulated e-commerce for consumers, merchants and PSPs alike, it also opens the door for everyday use of stablecoins. Charged by Concordium Protocol-Level Tokens (PLTs), it enables instant, trusted payments in stablecoins pegged to major global currencies. By combining verification and seamless settlement, Verify & Pay makes stable, digital payments practical for daily purchases–accessible to everyone, everywhere. That’s the essence of PayFi!
